- —Hannibal and Winn Schott[src]
Hannibal took position outside Kara Danvers's apartment building and used his power to take control of Mon-El's body and had him fight against Kara and later Guardian. He was discovered by Winn Schott and bluffed into stopping his control of him and then locked in the D.E.O. There, J'onn J'onzz used his telepathic ability to look into Hannibal's mind where he painfully revealed that the bounty of 300 Quartz Crowns was issued by Queen Rhea.
