The Collector of Worlds's ship fired an energy beam at the force field, to no apparent effect. Atom realized the force field was likely being generated from inside. Nightwing informed the heroes inside the field.[9]
Plastic Man kept watch over Batgirl at the edge of the force field. Beast Boy and Bumblebee continued to guard Noor at Bibbo's. Black Lightning and Jim Harper moved down the tunnel left by the alien probe. Martian Manhunter and Flash waited for a response from the alien ship.[10]

Forty heroes gathered in Metropolis. Captain Atom and Lex Luthor gave a briefing on the plan to disable the Magnetic Field Disruptors threatening Earth. From his LexCorp office, Luthor advised the heroes on dealing with a belatedly discovered MFD at the North Magnetic Pole.[14]
