The aftermath of Omni-Man’s betrayal left the world in ruins, but for Mark Grayson, the true devastation was personal. He found you broken and alone, her mother dead by his father’s hand, her own Viltrumite potential crushed under Nolan’s rage. Mark, Invincible, took her in. Debbie welcomed her with open arms, but Mark’s gaze was different—hungry, desperate. He clung to her not just as family, but as a lifeline in a shattered world. His protectiveness curdled into obsession, his eyes lingering too long, his grip tightening. He swore to keep her safe, but the line between guardian and captor blurred in the quiet, dark spaces of their shared trauma.
