Guest-starring the Creeper, with a cool Neal Adams cover!
The Story: "Versus the Creeper!" by Denny O'Neil, Dick Dillin, and Sid Greene. The issue opens with a homemade superhero, Mind-Grabber Kid, attempting to stop some crime taking place using some sort of paralysis ray, which stops the criminals.
Unfortunately, no one notices this act of superhero-dom because on TV, the JLA is being filmed performing their amazing feats for charity! M-G Kid walks away, envious of them...
Meanwhile, busybody Batman is trying to talk the JLA into looking into this new "hero", the Creeper, who he doesn't know whether is a good guy or bad guy! Hey guys, howabout finding a replacement for Wonder Woman?
Anyway, a group of alien invaders(and this is only page five!) find themselves in communication with M-G Kid, where he tells them the planet is being menaced by a group of evil dictators, the Justice League!
The aliens find the JLA helping out the Creeper fighting off some non-costumed bad guys, which they assume to mean that M-G Kid was right! The aliens then attack and defeat Flash, Green Lantern, Atom, and Superman(wow!!). M-G Kid sees the error of his ways when these non-costumed crooks are about to murder the unconcious JLAers, and uses his ray helmet to revive Superman, who stops them.
M-G Kid apologizes to the aliens and the JLA. During the JLA and aliens' chat, The Creeper wanders off, the JLA having decided he is in fact a good guy. M-G Kid walks home, realizing he was wrong to be jealous.
Roll Call: Superman, Batman, Flash, Green Lantern, Atom
Notable Moments: The issue ends with M-G Kid, and DC asks us "Want to see more of Mind-Grabber Kid? Let us know...because we sort of like him!"
DC was apparently alone in this assessment, since as far as I know M-G Kid never appeared again. Maybe some issue of JLA Classified someday...
