With a little help from Akira, Hawkeye manages to leave Diamondback distracted long enough for Hikaru to stop the disguised Riley from stealing more DISKs from within a bank. Unfortunately, Riley sends out King Cobra to send Hikaru flying. After being caught by Spider-Man and handed Thor's DISK, Hikaru releases Thor, who interrupts King Cobra's offer to finish the kids off in exchange for permanent freedom with a hammer toss.

Riley is forced to withdraw King Cobra and escape with Tim and M.O.D.O.K., as Hikaru and Thor introduce each other formally. Later, Pepper and Iron Man give Akira and Hikaru a place to stay in New York while the crisis continues.
