Although he desires to be a good hero, Superboy has anger issues. Having spent his first 16 weeks of existence as a science project and mind-controlled puppet, Superboy is defiant and does not like being told what to do or being dismissed. He often behaves with an air of extreme confidence, due in large part to the fact that he is Superman's genetic clone, and was created in order to replace him. This makes him exceedingly overconfident in his abilities to the point that he ignores the help of others and impulsively throws himself into situations that he cannot handle on his own. Despite this confidence he worries about living up to his namesake, Superman. Due to the fact he never really had the opportunity to interact with anyone until recently, Superboy is somewhat anti-social and has a hard time getting along with others or showing his emotions. As such he constantly behaves in a confrontational manner to all people, even those who are attempting to be kind towards him. Even simple things like making amends with people who he has wronged is a tough concept for him to understand. However, he has learned quickly and has become not quite so silent, to the point of even carrying on a conversation without getting angry.
By 2016, Superboy seems to have become more mellow and in touch with his emotions, but he is still angered whenever Miss Martian uses her powers invasively. He has also become more experienced and uses his intelligence more, planning attacks instead of going in with physical strength.
Superboy is a partial genetic clone of Superman, and as such shares many of Superman's physical traits. At the time of his liberation, Superboy was physiologically 16 years old, however, chronologically he was only 16 weeks old. As a side effect of the cloning process, Superboy will never visibly age, thus looks identical in the five years since his awakening. Superboy is a Caucasian male with short black hair and blue eyes. He is noticeably taller than most people of his physiological age and is quite muscular, likely due to his partial Kryptonian genes. He is considered very handsome by most girls in his physiological age group and is typically seen with a frown on his face, rarely with a smile.
Superboy used to wear a black T-shirt (though he has worn a long sleeved shirt on occasion) with the classic S-shield in red and at times wore a brown leather jacket. He also donned dark blue fatigue pants tucked into dark-brown combat boots with a large buckled-belt. In 2016, he wears a long sleeved variation on his traditional black with red S-shield shirt and fingerless gloves.
On March 21, 2010, Project Cadmus initiated Project Kr. It was based on Project Match, an earlier attempt to clone Superman. Because of the incomplete DNA sequences, "Match" was deemed a failure, a mistake they did not repeat on Project Kr. For this new project, gaps in the sequences were filled with human DNA, with Lex Luthor as the donor. He was kept in a containment pod along with three G-Gnomes, who telepathically controlled him and educated him with the knowledge of a boy of his physiological age.

Aqualad, Robin and Kid Flash discovered the Genomorph project and Superboy, whom they liberated. The four youths stood up to their mentors and declared they were ready to prove themselves as heroes. While Batman considered their argument, Kid Flash had Superboy stay with him. Together they faced the Terror Twins at Central City Mall. They formed a covert ops team and were given their own headquarters in Mount Justice, and were introduced to Miss Martian.
Left alone in the Cave briefly, Superboy experienced a telepathic reconstruction of Joker's attack on the Cave years prior, when it still served as Justice League headquarters. It was caused by a G-gnome that had missed Superboy and followed him from Cadmus.
The Team grew restless from the lack of missions, but tried to get to know each other better. They fought Mister Twister, eventually defeating him, which renewed their faith in the Team. The Team later went on a campout where they shared the stories of how they became heroes.
The Team's first official mission was to investigate the stoppage of Venom production in Santa Prisca. Superboy and the rest of the Team eventually agreed Aqualad was their natural leader. The Team was then sent to stop a plutonium robbery. They defeated Psycho-Pirate and Atomic Skull, capturing the former.
- Main article: Superboy in August 2010
Superboy, along with the rest of the Team, began taking training sessions with Black Canary. The Team were assigned to guard shipments of the disassembled Amazo. Professor Ivo was able to retrieve and reassemble the robot, but the Team defeated Amazo and captured Ivo.
Artemis joined the Team, just before they were assigned a mission by Red Arrow: to protect Serling Roquette from the League of Shadows while she worked on a counter-weapon to the Fog she developed.
The Team took a class in espionage from Captain Atom. When the lecture proved boring, Captain Atom assigned them a cold case mission–to determine whether or not Air Force captain Nathaniel Adams was framed for the murder of his superior during the Vietnam War. The Team was ultimately successful in determining Adams' innocence.
The Team was later sent by Red Tornado to protect the Helmet of Fate following Kent Nelson's disappearance. While the Helmet was kept safe, Kent died defending it. Two days later, Superboy and the others attended Kent's funeral.
Later, Batman ordered the Team to track Clayface through Gotham City while he worked on a way to defeat him. The Team engaged Clayface against Batman's orders–the Team was soundly defeated, but saved by Batman at the last moment. That evening, Superboy reluctantly attempted to help M'gann cook.
- Main article: Superboy in September 2010
Batman sent the Team to Bialya, where they encountered Psimon, who blocked their memories of the prior six months. Superboy was left with no memories at all, and was captured and tortured. Miss Martian rescued him and restored his memories, and he took Sphere as a pet.
Aqualad invited Superboy and Miss Martian to visit Atlantis with him. They met Kaldur's parents, then went to the capital, where they helped thwart Ocean-Master's plot to steal Queen Mera's powers.
Superboy, Aqualad, Kid Flash and Miss Martian were captured when the Cave was invaded by Red Torpedo and Red Inferno. They were eventually rescued by Robin and Artemis. Like the rest of the Team, he was rendered unconscious by Red Tornado, who fled with his "siblings". Superboy, like the rest of the Team, was furious to discover Aqualad had withheld information about a possible mole on the Team. Batman assigned the Team to investigate reports of gorilla attacks in India. After defeating the Brain and freeing his Kobra-Venom-enhanced animal slaves, Superboy was satisfied with Aqualad's reasons for keeping the secret and picked up a new pet: Wolf.
The Team was then sent to investigate reports of another Kobra-Venom operation in Bwunda. The Team were ambushed and captured by the Brain's gorillas, but eventually freed themselves and helped the gorillas stage a rebellion against their captors.
- Main article: Superboy in October 2010
The Team was sent to destroy the central control system being used by the Injustice League to attack a number of cities worldwide with giant plants. They successfully destroyed the control plant, and the subsequent arrival of the Justice League was enough to force their enemies to surrender.
The Team was introduced to Zatanna. They went on an unauthorized mission to find Red Tornado. They discovered the robot had not betrayed them and, together with Red Inferno and Red Torpedo, they were able to destroy Red Volcano and prevent the Yellowstone supervolcano from devastating the planet.
Superboy and the rest of the Team took part in a telepathic training simulation run by Martian Manhunter. It went wrong when Artemis's "death" caused Miss Martian to take control, causing them to forget it was not real. Superboy "died" heroically, sacrificing himself to allow the others to infiltrate the alien mothership. When the simulation was ended, Conner, like the others, was left devastated.
The Team was given therapy by Black Canary. Superboy stormed out of his session, and took a joyride on the newly transformed Sphere with Wolf. They encountered the Forever People and helped them retrieve stolen technology from Intergang. Seeing that she was in good hands, the New Gods allowed Sphere to stay with Conner. After returning to the Cave, Superboy admitted he was guilty that he wasn't devastated by the simulation; he had finally gotten to feel what it was like to be Superman.
- Main article: Superboy in November 2010
After all the adults in the world disappeared, Superboy and the Team worked with Zatanna to find the cause. With help from Captain Marvel they were able to communicate with the adults in their own separate dimension and coordinate an attack on Klarion and his group of sorcerers, merging the dimensions back into one.
Superboy joined a mission to Qurac to discover why the nation's leader decided allow Bialya to absorb Qurac. They saved Marie Logan and her son from Bialyan tanks, though Gar was injured during a reprisal attack. The Team went on to the capital, where they successfully defeated Psimon, who was controlling Harjavti.
On Thanksgiving, Superboy received an ultra-sonic message from Lex Luthor, who encouraged him to investigate Cadmus. Superboy found another Superman clone and attempted to free him. The clone was enraged and mindless, and Superboy was reluctantly forced to put him back in stasis. His mission allowed Luthor to discover the location of Genomorph City. Connor also received a number of Shields to enhance his powers, and discovered that he had some human DNA—from Luthor, who had some level of control over Superboy.
- Main article: Superboy in December 2010
M'gann and Conner visited the Logans before going to Dhabar to protect Harjavti from a suspected attack by Queen Bee. They and Superman intervened as Deadshot apparently attempted to kill Harjavti. Superboy became enraged by using a Shield and savagely beat Deadshot.
Superboy and the rest of the Team, now including Rocket, responded to an alert that Cheshire had been spotted. They found they had been lured into a trap, but were nonetheless successful in defeating their enemies and capturing the case that had eluded them previously. Realizing the trap meant there must really be a mole, Superboy, Artemis and Miss Martian revealed their secret links to their enemies to the rest of the Team, and found acceptance. The Team ambushed Lex Luthor, Queen Bee and their allies on Santa Prisca and captured several villains, though Luthor and Bee escaped.
They returned to the Cave triumphant, but were shocked to find Batman waiting to tell them the mole was Red Arrow. Aqualad, Superboy, M'gann and Artemis went to find Roy, while the others investigated Red Tornado's mysterious shutdown. They found Red Arrow, who explained he had unwittingly been under the Light's control. The Team infiltrated the Watchtower and freed the League from the Light's control.
As the clock struck New Year, Miss Martian and Superboy kissed. Later, they were locked in a passionate hug when Superman arrived to talk to him. The Man of Steel congratulated him, and tried, uncomfortably, to create another conversation. He inquired about Superboy's civilian name, Conner Kent, and revealed his own secret identity, Clark Kent, to him. Conner was surprised and apologized for the similarity, but Superman was proud of the connection. Superboy was happy with the acceptance.
Superboy and Miss Martian joined Nightwing and Aqualad in the mission room to debrief Artemis's mission to Olympia. She had not succeeded in finding missing scientist Helena Sandsmark, but stuck a tracer on Sportsmaster. This lead them to Siberia.
Superboy lead a squad to Siberia. As soon as they arrived, they noticed earthquakes, as was the case in Greece. However, as something interfered with their comm device, their first objective was to knock out whatever jammed the signal. After a series of fights with Shadows and hitching a ride across the river on a cargo ship, they found the jammer in a LexCorp camp.
In the camp, they also found captured villagers being wired up to ice machines. They were guarded by Shadows and LexCorp robots. They proved little opposition. They eventually came to an ornate ice garden, where they found Killer Frost. Though she had back-up from more LexCorp Spider Bots, she too was defeated.
They continued to trace the signal of Sportsmaster's tracer. They had to travel through ice caves and fight their way through more Shadows and LexCorp bots, but eventually found Sportsmaster and Icicle Jr. in a room with a laser drill. Superboy confronted them just as they were planning to leave. Alpha Squad defeated them both, and took an ancient artifact from him. However, the villains escaped, and the drilling and the fight made the mountain unstable.
Superman linked up with the squad, and together, they had to fight their way through a series of locks and tunnels while staying ahead of the avalanche. With Superman's help, they managed to escape and save the surrounding villages from the avalanche.
Back in the mission room, Batman congratulated Superboy on his successful recovery of the artifacts and saving the villages. Superboy, however, was somewhat displeased as they couldn't find doctor Sandsmark.
Further missions to Santa Prisca and Gotham City yielded more artifacts, and they found doctor Sandsmark. The Team discussed what to do next; they discovered the artifacts were tied to the legends of Marduk and Tiamat. As disasters intensified, Superboy stressed the need for urgency.
- Main article: Superboy in December 2015
On the first day of the month, Superboy was assigned to help guard Noor Harjavti at a political rally in Metropolis. He was one of a number of powerful superheroes and villains teleported from Earth to a crystalline prison on the Moon by Kylstar. He and the Leaguers captured with him escaped their cells, but were soon brought before Kylstar. The heroes fought him, and eventually managed to convince him of their right to freedom. Kylstar released all the prisoners who did not wish to join his army. Superboy and the others were teleported to the Collector of Worlds's vessel. There they helped fight the alien android and convince him to spare Metropolis.
Superboy's relationship with M'gann ended after he broke it off because of his disapproval of how M'gann used her abilities to extract information from villains, and she tried to make him forget that he was angry with her. He did not like to see her kissing her new boyfriend, Lagoon Boy, and thought he was a jerk.
At some point, Superboy, Nightwing and Miss Martian were invited to join the Justice League, but turned it down, stating that they were happier with the Team for now.
- Main article: Superboy in January 2016
On New Year's Day, Superboy joined a squad assigned to capture Clayface. Following the revelation of the Krolotean invasion, he was assigned to Zeta-squad and sent to Rann. Zeta was able to force the Krolotean force on Rann to retreat, retrieve Zeta-Shield plans to prevent further incursions and discovered why the League were wanted criminals on Rimbor. He then took part in the attack on the Kroloteans's last outpost on Earth. Towards the end of the month, he bade farewell to Superman, who left with the other accused Leaguers to face trial on Rimbor.
After the destruction of Malina Island, Superboy suspected the bomb was smuggled to Earth via boom tube. He suspected Intergang's involvement, and discovered Bruno Mannheim had come out of hiding. He took Blue Beetle and Wolf with him to follow them.
The heroes encountered Mannheim and Whisper A'Daire at the Hall of Justice. Mannheim activated an Apokoliptan device, which revived the residual energy in the Appellaxian husks inside the Hall's trophy room.
Superboy and Wolf attacked the merged golem, but were no match. After Blue Beetle unwisely attacked it with a sonic blast, which was bounced back, all three of them were knocked out. Intergang and the golem escaped.
Giving chase, Superboy berated Blue Beetle for not doing his homework on the Appellaxians, the League's first case, and explained their origins to him.
They caught up with the villains, and Sphere destroyed the control device. With Mannheim no longer in control, the golem made his way to the Arlington Nuclear Power Plant. Blue Beetle and Superboy restrained Mannheim and A'Daire before heading to the power plant.
The golem repelled all of Superboy's and Wolf's attacks. Blue Beetle's armor figured out a way to talk to it, and they learned that it wanted to end its mechanical life to stop the pain it was in. Superboy offered help, but at that moment, a sonic blast from the forest destroyed the golem.
When they returned to the clearing where they left Mannheim and A'Daire, they found them alive, but unresponsive, which angered Superboy.
- Main article: Superboy in March 2016
Superboy took part in the mission to guard the Earth-Mars communication satellite launch. He posed as Superman for the benefit of a press conference, then piloted the Bio-Ship when Black Manta's troopers attacked. The mission ended in disaster, with the satellite destroyed and Artemis apparently killed by Aqualad.
Superboy mourned Artemis's death. His birthday went by largely unmarked. Superboy was in the Cave when it was infiltrated by Kaldur's squad. He was captured, but left behind. He was able to escape with the others before Kaldur destroyed the mountain.
Superboy then went undercover as a Manta trooper as part of the Team's plan to rescue their captured comrades. They found them on an alien vessel in the Pacific Ocean. The Team and a number of kidnapped teenagers were successfully rescued, but the Team had to fight their way past Black Beetle to escape. Beetle took down many of the Team, including Superboy, with embarrassing ease, but Blue Beetle was able to hold him off for long enough for everyone to make their escape.
Superboy was with Nightwing, M'gann, Mal Duncan and Wolf at a warehouse, which Nightwing said he set up for those who had lived at Mount Justice as a new place to stay. Superboy said the accommodations were fine, but Mal indicated he wanted to make other arrangements. Nightwing suggested everyone head to the Hall of Justice to gather belongings that were salvaged from Mount Justice.
Superboy joined Mal and M'gann at the Hall of Justice, where Bumblebee, Zatanna and Captain Marvel were also present. They heard a voice announcing a challenge to Earth's champions and Zatanna and Marvel went to investigate. L-Ron arrived, generated a force field around the Hall and Despero appeared, attacking Captain Marvel. Superboy left with Bumblebee to assist.
Despero mentally subdued Zatanna and neither Marvel nor Superboy was able to take down Despero. Marvel, who had changed into Billy Batson in an attempt to stop Despero, was mentally subdued as well, leaving Superboy to fight Despero. He was no match for Despero and, as Despero was about to finish him off, Bumblebee intervened, but she was mentally subdued as well. Mal Duncan appeared, dressed in Guardian's armor, and told M'gann telepathically he was going to buy some time, so M'gann escaped with Superboy and Bumblebee.
As the trio rode down an elevator, Superboy recovered, asking what happened, and Mal told him telepathically of his plan. Superboy asked why M'gann hadn't attacked Despero mentally and M'gann said she couldn't do it. Superboy told M'gann she needed to come up with an idea before something happened to Mal.
Superboy went to assist Mal, but Despero took both of them down. M'gann then reached the others telepathically, allowing Zatanna to cast a spell that left Despero stunned and allowed Superboy to take him down. Billy then arrived and transformed back into Captain Marvel to take out L-Ron. After L-Ron activated an explosion, Marvel rushed to protect Superboy and the others as the Hall crumbled down.
Superboy was with Nightwing, Lagoon Boy and Beast Boy at the warehouse, watching the broadcast of G. Gordon Godfrey's show. They are surprised to see Mal Duncan there, who tells them his other arrangements fell through. He inquires about M'gann's whereabouts and Nightwing said she was staying somewhere else. Superboy looked concerned.
M'gann, posing as John Jones, was staying at her uncle's apartment. Superboy knocked on the door, saying he needed to talk to her, and M'gann let him in.
Superboy was present at the warehouse as Nightwing assigned a squad to investigate LexCorp Farms.
After the squad completed its mission, Superboy was present with the squad members, Nightwing and Green Beetle at the farm owned by Jonathan Kent. Jonathan allowed Green Beetle to stay in his barn, saying he had seen stranger things before and that he was happy to have any reason to see one of his boys, referring to Conner.
Superboy was at STAR Labs with other Team members and Adam Strange as Green Beetle explained an additive that the Reach added to a beverage being marketed to the public. After the briefing was completed, Lagoon Boy asked to speak with Miss Martian. She looked at Superboy, who simply shrugged.
Lagoon Boy and Miss Martian were ambushed by Deathstroke and Tigress, prompting Lagoon Boy to request backup. Superboy and Nightwing Zetaed to Chicago, but were too late as Deathstroke and Tigress had kidnapped Miss Martian and Lagoon Boy was injured.
Superboy and Nightwing were with Lagoon Boy at a hospital, trying to calm him down as La'gaan was insistent on going to help Miss Martian. He accused Superboy of no longer caring about her, to which Superboy told him he had no idea how he felt. Nightwing then revealed to the two that Kaldur was working in deep cover, that they faked Artemis's death and that she was working undercover as Tigress. La'gaan was upset about this but Superboy told him Nightwing must have had a good reason for keeping the information a secret.
When the two left La'gaan's room, Nightwing thanked Superboy for backing him up, but Superboy sharply responded that Nightwing had no idea what his secrets had caused. He told Nightwing that, because M'gann thought that Kaldur had really killed Artemis, she fried his brain when she found him aboard the Reach research ship. He then deduces that Tigress must have kidnapped M'gaan to help Kaldur but states that M'gann may not be able to help him, meaning that Nightwing's secrets have put M'gann, Artemis and Kaldur in great danger.
Superboy was among those present for a briefing from Captain Atom about an object the Watchtower detected, about to pass in front of Rhea, but Nightwing realized it would pass behind Rhea. The large object is later identified by Green Beetle as the Warworld.
Superboy was among the Team members who snuck on board the Warworld after Justice League members occupied Mongul, the despot who controlled the large satellite and was attacking Earth. Superboy reported that Alpha Squad—himself, Wonder Girl, Arsenal and Wolf—were headed to the command center to stop Mongul.
Alpha Squad had to fight off drones that were protecting Warworld and Superboy was not happy that Arsenal fired a rocket launcher at some drones without warning him. Alpha Squad ultimately reached the command center but Mongul easily swatted away Superboy, Wonder Girl and Wolf and Arsenal's attacks were equally ineffective. When Superboy charged Mongul again, Mongul grabbed him, noted the symbol on his shirt and asked the Kryptonian if he thought he was the only one to come from a world with a red sun.
After Bumblebee created a power surge to overload Mongul's control device and leave him dazed, Superboy called for an all-out assault on Mongul. Alpha Squad's efforts took him down and Wonder Girl was able to subdue Mongul with her lasso. As Superboy notified the others that Mongul was down, Batgirl congratulated Alpha Squad, but Superboy said somebody else was responsible for shutting down Warworld.
Alpha Squad was the last of the squads to return to the entry point, given how heavy Mongul was. As Superboy and Wonder Girl carried Mongul, Blue Beetle—who had secured the crystal key that activated Warworld—suddenly hit Impulse with the crystal, then attacked the rest of the Team. Beetle charged Superboy and took him down, leaving Wonder Girl trapped underneath Mongul, with Beetle pinning her arms down with staples. Arsenal, terrified at the thought of being captured again, opened the entry hatch, causing Sphere to be sucked into space. Blue Beetle was able to close the hatch and take other Team members down, and as he fired a staple at a fleeing Arsenal, Superboy took the blow and Arsenal got away. Superboy asked what Blue Beetle was doing and Beetle told him that resistance would be foolish given the lack of oxygen in the entry point, and then used his staple gun to knock Superboy out.
Superboy was trapped in a stasis cell under the Reach's control along with the rest of the Team.
The Team returned to their warehouse base.
When Miss Martian returned to the warehouse with Lagoon Boy, she asked Nightwing where Superboy was. Nightwing replied that he had gone out with Wendy Harris.
Along with Guardian and Bumblebee, Superboy shadowed the Light-Reach summit held in an underground cavern. After Aqualad's betrayal was discovered, the Team sprung their trap, and Superboy's squad sealed off the entrance used by the Reach. During the ensuing melee, Superboy fought off Reach soldiers and League of Shadows agents with his brute strength. He engaged Black Beetle, but was easily outclassed in their physical confrontation. Despite this, the battle ended with the heroes victorious, with the capture of the Reach ambassador, Black Manta, the Brain, and Monsieur Mallah.
Superboy, Miss Martian and Adam Strange arrived at the court at which the six Justice League members were standing trial. M'gann told Icon they had evidence to clear the Leaguers but Icon told her it was too late. Miss Martian and Superboy appealed to the Tribunal, who admitted the evidence was compelling but the court had already ruled. When Icon objected, the Tribunal asked for something "more". Miss Martian and Superboy improvised, saying that the case was a chance for the court to demonstrate justice prevailed on Rimbor, that more cases would thus be brought to the court and thus the more "mores" the tribunal would receive.
As the Tribune privately discussed the matter, Miss Martian admitted to Superboy that their deteriorated relationship was her fault and that she knew he was dating Wendy Harris, but Superboy replied he was acting as a sounding board between Wendy and her real boyfriend, Marvin White. The Tribunal then exited their chambers and announced all charges against the Leaguers had been dropped. Superboy, Miss Martian and Adam Strange then teleported back to Earth.
When magnetic field disruptors planted by the Reach threatened the Earth, Superboy joined 39 other heroes of Earth in a briefing in Metropolis. The heroes would use a computer virus provided by Lex Luthor to safely disable the devices. The heroes were paired off with another into twenty squads: one member would run interference against Beetle-tech Drones guarding the disruptors, allowing the other to get close enough to plant the virus. . Within thirty minutes, all squads had succeeded in their mission.
Superboy and Miss Martian were in the memorial garden, observing Robin and Wonder Girl. Superboy asked how long they had been a couple and Miss Martian replied that Cassie got the courage to kiss Robin after realizing how short life was when Wally passed away. The two agreed that that kind of courage could be hard to come by, but they were then summoned by Aqualad to the mission room. There, Batman informed the Team that the Watchtower would serve as their headquarters because the Team earned the right to fight alongside the Justice League. Aqualad then assigned Superboy, Miss Martian and Beast Boy to Alpha Squad to go to Mars to assist B'arzz O'oomm.
Powers and abilities
- Kryptonian physiology: As a partial genetic clone of Superman, he has most of the physical abilities of a Kryptonian who has absorbed the solar energy of a yellow sun. However, due to the human DNA supplied by Lex Luthor, he lacks the more advanced powers of flight and heat vision and presumably is incapable of ever acquiring them. In addition, his existing powers are considerably inferior to Superman's.
- Super strength: This is one of Superboy's main abilities, allowing him to easily pick up or carry heavy objects.
- Invulnerability: Like Superman, Superboy is nearly indestructible. This invulnerability allows him to rush into dangerous scenes with little care for what might actually happen. Out of all his teammates, Superboy has taken the most punishment from their missions but has displayed no lasting injuries. He has been tackled through walls, shot with guns and explosives, had his feet dipped in lava, and has come out with no obvious physical damage. He has yet to be permanently injured, but he does experience pain.
- Super hearing: Superboy can pick up the faintest of sounds over long distances, as well as high frequencies not audible to regular humans.
- Infrared vision: This ability allows Superboy to visually detect heat signatures, allowing him to easily see in the dark.
- Hand-to-hand combatant: While normally relying on his sheer strength, Superboy has developed highly proficient combat skills from his training under Black Canary. He is especially good at grappling and takedowns. 
- Genomorph programming: While Superboy was being force grown, G-Gnomes telepathically fed him information in lieu of a traditional education:
- Motorcycle: Superboy has his own personal mode of transportation: a customized motorcycle. He used this on his mission to guard the Amazo parts. He left it behind to go after the MONQIs. He liked working on it in his spare time.
- Sphere (Super-Cycle): This piece of New Genesis technology is actually a "she" that bonded with Superboy. Some months later, Sphere's abilities were brought to light.
- Shields: The shields given to him by Lex Luthor allow Superboy to suppress his human DNA, permitting his full Kryptonian abilities to surface for an hour, including:
- Solar suit: Upon being released from his cryogenic suspension in Cadmus Labs, Superboy wore a white solar suit with a red Superman S-symbol on the chest. The suit allowed him to absorb Yellow Sun radiation to fuel his powers even underground. The suit was damaged during the fight with Blockbuster. While staying with Wally West, he continued to wear the tattered solar suit until he bought new clothes from Forever Sixteen in the Central City Mall three days later.
- Code words: When Lex Luthor said the words "Red Sun" to Superboy, he blacked out for several hours, remaining completely still until he snapped out of the hypnotic trance. Miss Martian psychically excised this programming from his mind, and confirmed that no other code words were implanted.
- Kryptonite: Due to his Kryptonian DNA, Superboy is vulnerable to the unique radioactive properties of this green mineral.
- Main article: Superman
Superboy is Superman's partial clone. During incubation at Cadmus Labs, Superboy was programmed to both take over for Superman if he ever died and to defeat Superman if he ever went bad. He respected Superman, to the extent that Aqualad was able to convince him to resist the G-Gnome's telepathic control by asking "What would Superman do?".
Originally, Superboy longed to meet Superman, but when they finally met, Superboy was angered by Superman's initial reaction of surprise and near disgust at having a clone. After the matter was explained, Superman tried to show some support for him, but failed and quickly excused himself. Over the next several days, while staying with Wally West, Superboy repeatedly wondered if Superman knew where he was, and when they'd meet again.
For the first six months after that, Superman had actively avoided Superboy and tried to push responsibility of him onto Batman and Red Tornado. Even when Superboy directly asked Superman to help him figure out the extent of his powers, Superman merely brushed it off and quickly left. This apparent rejection made Superboy angry and led him to make several reckless errors of judgment, such as attempting to take down the powerful Amazo by himself.
Following being saved from Vandal Savage's mind control of the Justice League, Superman has come to accept Superboy. He revealed his secret identity, and approved of Superboy taking on his last name "Kent". Since 2011, Clark has given Conner a Kryptonian name, Kon-El. He now views Superboy as his little brother as opposed to his son.
- Main article: Lex Luthor
Lex Luthor provided his genetic material to Superboy, and has tauntingly referred to him as his "son". Knowing him as a villain, Superboy disapproved of his connection to Lex Luthor, but Lex exploited it in the hopes of bringing Superboy to the Light.
- Main article: Aqualad
Miss Martian and Superboy liked each other from the moment they met, and throughout their missions came closer and closer together. They eventually became a couple but did not tell their friends. Nonetheless, Aqualad and Robin found out easily, as did Zatanna, who informed Artemis, who told Wally and the latter was very sad to hear the news.
Five years later, they are no longer a couple. Though it was his decision, Superboy is still uncomfortable seeing her with Lagoon Boy. Superboy broke up with her when he caught her trying to wipe his mind of his anger at her abuse of her telepathy.
- Main article: Artemis
Artemis had a crush on Superboy from the moment she first saw him—before she came on the Team. During her first mission, she did not shy away of openly flirting with him, which made Superboy uncomfortable. She was distraught when Zatanna pointed out to her that he was in a relationship with Miss Martian.
Background in other media
- In the comics, when Superboy was first introduced, he lacked all the powers he currently demonstrates in the cartoon series. Due to the fact he escaped his growth tube before reaching maturity and due to issues regarding cloning a Kryptonian (a Kryptonian is completely indestructible thus collecting a DNA sample is nearly impossible), Superboy was instead given tactile telekinesis, which allowed him to simulate Superman's primary powers (flight, strength, invulnerability). As time passed and Superboy matured, he began to manifest all the normal Kryptonian powers, causing him to use his tactile telekinesis less and less. In the cartoon however, Superboy has not developed tactile telekinetic abilities. Instead, his powers are mostly the same as Superman's, although he lacks some abilities such as flight and heat vision.
- Superboy's personality is distinctly different in Young Justice from how it was in the pre-New 52 comics. There, Superboy was immature, talkative, flirtatious and comically rude, which slowly was replaced with a more mature attitude. Here, his personality is more brooding and somber, with bouts of uncontrollable anger and with a lack of understanding basic human interactions at times.
- Superboy's romantic relationship with Miss Martian is something introduced specifically for the series. In the comics, Superboy had a long-term relationship with Wonder Woman's second sidekick Wonder Girl (Cassandra Sandsmark), that ended recently. Before that, he had multiple love interests, including Tana Moon, Roxy Leech and Serling Roquette.
- This is his first animated appearance.
