Dragon King uses a hood with eye holes that completely covers his face. In the center, it has a snake-like symbol that runs from his forehead down to the neck. He also wears a skintight spandex uniform with briefs over his tights and matching gloves and boots. Around his shoulders, he dons a matching cape with a long collar rising slightly over his temples. Around his waist, he wears a satchel.
This is Dragon King's first animated appearance. He was an agent of the Japanese during the war, who created a force field around Axis-controlled Europe and Asia, barring superpowered heroes from the fight, with mystical objects like the Spear of Destiny and the Holy Grail. He was featured in Geoff Johns's Stars & S.T.R.I.P.E. series, as the father of Stargirl villain Shiv. There, he was revealed to be responsible for the death of Firebrand.
