 Pier 4 was eventually destroyed during a battle with the longtime Fantastic Four supervillain Diablo, after which the team received a new Baxter Building, courtesy of one of team leader Reed Richards' former professors, Noah Baxter.This second Baxter Building was constructed in Earth's orbit and teleported into the vacant lot formerly occupied by the original.A number of characters are closely affiliated with the team, share complex personal histories with one or more of its members but have never actually held an official membership.
