Fan Casting Mister Terrific in Waller: Checkmate

A brilliant inventor and former member of the Justice Gang, Michael Holt steps away from public heroics after growing uncomfortable with how metahumans are being weaponized by governments and intelligence agencies. Now operating independently as a technological consultant, Terrific becomes a reluctant ally to Checkmate, providing advanced surveillance and counter-intelligence tools as they investigate Peacemaker’s disappearance — while insisting that any operation he supports must expose the truth rather than deepen the cycle of secrecy Waller helped create.
