Uncanny X-Men Annual #12 (1988)
In which The X-Men had recently been eliminated, and Mojo, living in a universe that centers around TV ratings (who profited off of broadcasting their exploits), is incredibly distressed and auditioning new X-Men to replace them. (Special appearance by Vanna White, apparently.)
We see genderbent X-Men, animal X-Men, mech X-Men, etc., and of course, the X-Babies. It’s so friggin’ glorious.
THIS is what made me love comics in the first place.
PLUS. ART ADAMS and his flawless art.
