Patchwork is one of the many enemies of the Hulk and like a few of them has obtained a gamma-mutated form not dissimiliar to that of the original Hulk - however while Hulk is fuelled by rage Patchwork is fuelled by a far more disturbing force: namely sexual suppression.

In his past Patchwork was caught reading "girlie magazines" by his grandmother - who threatened to cut off his fingers as punishment and this seems to have caused severe problems later in life.

Patchwork now exists as a killer who takes apart his female victims in order to stitch the bodies together in an attempt to create a "perfect" woman - making him in many ways a gamma-mutated version of a severely unstable serial-killer.
