He

Born as Dr. Marcus Venn, a prodigy whose brilliance was matched only by his complete disregard for ethical boundaries, He conducted his most ambitious experiment in a hidden laboratory deep beneath the city—a portal that would theoretically allow instantaneous travel across dimensional barriers. When a rival scientist sabotaged his calculations out of jealousy, the gateway collapsed catastrophically, and the resulting spatial implosion didn't kill him; instead, it inverted his entire physical structure, turning organs, muscle, and bone into a nightmarish configuration of inverted flesh and exposed systems that defied biological explanation. Rather than surrender to despair, He engineered a titanium exoskeleton of his own design, a mechanical prison that would both contain his grotesque form and keep him alive through synthetic stabilizers and pharmaceutical cocktails administered directly into what remained of his nervous system. Obsessed not with restoring himself but with perfecting the very technology that destroyed him, He abandoned his former identity entirely, renaming himself with a single pronoun that reflected his new status as something neither fully human nor machine. He operates now as a ghost in the underground, selling his considerable skills as a thief and saboteur to the highest bidder, driven by a nihilistic philosophy that views his inverted existence as proof that conventional morality is as fragile as his former flesh. His laughter echoes from within the mechanical shell like wind through a tomb, a sound that carries the unsettling warmth of someone who has transcended suffering through sheer indifference to his own monstrosity.
