He authorizes the Salvation prison initiative as a decisive measure to prevent further metahuman crises, believing firm control is necessary to maintain order. While not the central antagonist, his leadership decisions — and refusal to revisit them — quietly fuel the conflict between A.R.G.U.S. and Checkmate.
