Peter Parker has joined the Fantastic four a few times in alternate Universes, like in Amazing Fantasy #1000 and an issue of What if. In the main 616 Universe, Spidey is an occasional member of the FF and sometimes helps the team fight big threats. At the beginning of his career, he tried to join the group for money, but the work wasn’t paid, so he left. Still, Spidey would have another chance to join the Fantastic Four years later. After Johnny Storm’s death in Fantastic Four #587, Spiderman became an official group member. The team’s new version was rebranded as Future Foundation and escalated to include more initiatives toward scientific endeavors and new members. Plus, they got new black-and-white versions of the uniform that look sleek as hell.
