Ultimate Spider-Man is a video game based on the comic book of the same name written by Brian Michael Bendis and illustrated by Mark Bagley. The game begins with a summary of Spider-Man (Peter Parker) explaining that his father and Eddie Brock worked together for Trask Industries to find a way to cure cancer; however, they died in a plane crash before completing his “Venom” suit, which would cure the carrier.
Spidey bursts into the vault containing the Venom substance and is covered by a portion of it, creating his black suit. It improved his normal superhuman abilities to new levels, but the suit tried to consume it and eventually drained him by the experience. Eddie later discovers what Peter did and takes the rest of the suit for himself, thus being born Venom.
