Free Comic Book Day 2025: Fantastic Four/Giant-Size X-Men #1

In advance of Marvel's First Family arriving on the big screen this summer, Ryan North and Humberto Ramos craft an unusual story in which the FANTASTIC FOUR respond to a most unusual interdimensional summons! And on the eve of the birth of the ALL-NEW, ALL-DIFFERENT X-MEN, there is one extra mutant in attendance. WHO is it? Only Collin Kelly and Jackson Lanzing can tell you! Plus, ANOTHER surprise! We're simply too good to you!
