Today's Fact
Marvel's First Family was a closed shop — until Ben Grimm personally handed his place to a lawyer from Los Angeles.
When the heroes came home from the Beyonder's Battleworld at the end of the original Secret Wars, one seat on the Fantasti-Car was empty. Ben Grimm had chosen to stay behind on Battleworld, the one place where he could shift back into his human form at will, and before leaving he asked Jennifer Walters to take his place. In Fantastic Four #265 (1984), by John Byrne, the team returned to Earth with She-Hulk as its official fourth member — the first outsider ever admitted to a team that had always been one family.
This was no weekend guest spot. Jen moved into the Baxter Building, fought the team's rogues, and held the roster spot through roughly thirty-five issues, until Ben's return reshuffled the line-up around Fantastic Four #300. Reed introduced her on that first cover with a question — was the world ready for her? — while Johnny Storm answered that he certainly was.
She worked two jobs the whole time. Jen kept her Avengers membership as a reservist while serving with the Four, which made her one of the very few heroes of the era carrying full duties on two flagship teams at once. The replacement was meant to be temporary; the stay stretched across three years of publication and permanently changed what the Fantastic Four could be — proof the family had room for someone who chose it.
Why It's Obscure
Everyone remembers the courtroom years. The Baxter Building years came first, and they lasted longer than most Avengers line-ups.
