Ishmael donning the crown of SABBAC, only to get fried by Black Adam upon doing so. Atom Smasher finds his corpse still holding the crown to his chest and he's put in a bodybag. You'd assume this was it for him, but then Adrianna discovers that the inscription on the crown alludes to the wearer resurrecting as The Antichrist. Cut to Ishmael in the bowels of Hell, greeted by six titanic devils who deem him their Evil Counterpart to the Champions empowered by the Wizards. Ishmael's charred corpse glows with hellfire, then explodes and reforms as a Big Red Devil.
