Bio: Weasel was a small time mobster. One of his associates, Jake Fox, was double crossed and almost murdered by the much more powerful mobster Nick Trask (and early enemy of The She-Hulk) over a stolen shipment from Stark International.
Fox reached out to Weasel to ask him for help as he knew Trask wouldn't rest until he found and killed him. Weasel at first said no, saying it was too dangerous to cross Trask. After Fox promised a hefty take from every single future job he pulled, Weasel agreed, not realizing Trask had entered the room and was hearing everything. The two set a meeting for later that night and as Weasel hung up the phone, Trask killed him. He sent Weasel's body to the meeting spot that he had set up with Fox, luring Fox in and killing him as well.
