The Ultimate version of this character was origina
The Ultimate version of this character was originally meant to be a cure for cancer, while further experimentation with its cells in that universe produced a creature that killed and resurrected a person living with this creature's greatest enemy. For reasons of insanity, this character was exiled to battleworld by its own kind where it was picked up by its greatest enemy during the Secret Wars storyline and briefly worn before its sentient nature was discovered by Reed Richards, leading this villain to be forced off through the resonance of church bells. Although Mac Gargan, the Scorpion, has been one of its hosts, its best-known host is a disgraced journalist who failed to find the identity of the Sin-Eater, Eddie Brock. For 10 points, name this black and white symbiotic enemy of Spiderman.
