As recounted in "Fantastic Four" (2018) #24, Iceman's induction into the FF did not feature Namor, but occurred during the early days of the FF and the original X-Men. One morning years ago, the youthful Torch 'quit' the FF in an immature fit of pique. That same day, the sensitive teen-aged Iceman left the X-Men after being laughed at by his peers for his poor showing in a Danger Room exercise. Iceman encountered the remaining FF members and assisted them with a day-long series of crises, being casually admitted to the team as a result. When the Torch discovered that he had been replaced, he attacked Iceman during the FF's current battle and forcefully declared that Iceman was "not" an FF member. The Invisible Girl forced the pair to work together to help defeat the FF's final opponent of the day. Iceman was then telepathically summoned back to the X-Men by Professor X, who praised his student's performance. Mr. Fantastic told the departing Iceman that he could return to the FF whenever he wanted. The Torch was also 'readmitted', with a penance of a week's laundry detail.
