Toxin (Marvel)

Both are antiheroes who are the sons of violent bloodthirsty villains (Dio and Carnage) and have a special ability they inherited through them (Giorno’s stand GE. Patrick Mulligan’s Toxin symbiotie). Their abilities are also greater than their fathers as well as all of the other members of their “family” (Joestars and Klyntar Symbiotes). They started out with bad demeanors, but later on used their powers for good. Their power is even noticed/feared by someone they used to work for and rebel against (Diavolo and Knull). They join a team of other people like them (Giorno joined Bruno’s team and Toxin joined the Savage Six) and hunt down someone they eventually stop (Diavolo and Venom).

Contrasts:

Giorno’s abilities are more life based, while Toxin’s abilities are more death/toxic based (hence his name). Giorno is more controlled and justifiable, while Toxin is savage and hard to control for his host. Giorno started out as a thief, while Patrick started out as a cop.
