Reed is helping cure Willie Evans Jr. of a cosmic radiation coma- but is it the boy's father who's the real problem? Can the team defeat Evan Sr.'s FF doppelgängers and cure his mutant son?

And a Child Shall Slay Them!

Nightmarish doubles of the Fantastic Four appear, and it is up to their real-life counterparts to stop them! The creatures have been created by a boy named Willie Evans Jr., whose father had been exposed to the same cosmic rays that the FF did, and have subsequently given his child the awesome abilities!

Notes

• Willie Evans Jr. was considered being included by John Byrne in a new teen X-group with Kitty Pryde, which of course eventually became the New Mutants. In an early stat sheet of Kitty, Byrne writes: "The concept here is that Ariel should be not so much a new member of the X-Men per se, but rather the first member of a SECOND team, a kind of 'X-Men in Training' team, which could possibly also include that black kid from FF #203. They'd all (However many there are-say 5?) wear this modernized version of the original x-costume, and each would occasionally go on missions with the first team".
