Fan Casting Derek Powers in Adil El Arbi and Bilall Fallah's Batman Beyond

Terry’s adoptive brother and a slick, insecure yuppie, Derek Powers craves his father’s approval and resents Terry’s every success. When his deal with Hugo Strange is threatened, Derek crushes his own father’s skull with a paperweight and fully embraces villainy. He is not a physical threat—he is a coward who uses wealth and betrayal. His final confrontation with Terry leaves him dangling from a grappling hook, exposed as the gutless traitor he always was.
