Take Heed of the Snake in the Grass. Episode 12

Barnaby attempts to confront Jake, but he manages to escape when Kotetsu charges in, causing Barnaby to lose trust in him. Ivan, who had been forced to act as a decoy in the form of Jake, is recovered and sent to the hospital. Jake challenges the heroes in a series of one-on-one fights, promising to surrender if he loses, but blow up the city's support columns if he wins. The first two heroes, Keith "Sky High" Goodman and Antonio "Rock Bison" Lopez, are easily defeated by Jake's ability to produce barriers. As Ivan reveals to the higher ups that Ouroboros' Kriem is controlling the Mad Bears piloting the mechs, Kotetsu fights a one-sided battle against Jake and ends up seriously injured. Agnes manages to delay the next match until morning to give the higher ups time to set up a jamming signal for the mechs. As Barnaby prepares for his match, Jake announces he'll destroy half the city if Barnaby loses.
