Not paying attention to them kills a lot of monsters. I'm hoping, anyway.

I've enjoyed a number of the kid-friendly, low-continuity Marvel Adventures books, and mistakenly thought this was in the same vein: close! From 2005, Marvel Age: Fantastic Four #11, "Here Is: the Impossible Man!" Plot by Stan Lee and Jack Kirby, written by Marc Sumerak, pencils by Joseph Dodd, inks by Justin Holman.

Instead of brand-new stories, I think this whole series was adaptations/modernizations of classic Fantastic Four issues, in this case Fantastic Four #11. The Impossible Man arrives on earth near a hobo camp, who won't share their chili without a little donation, which of course leads to Impy robbing a bank. Later confronted by the FF, who are called in by the befuddled cops, Impy explains how Poppupians "evolutionary processes are so swift (they) can spontaneously change into anything," which an off-puttingly young-looking Reed seems to find, well, impossible.

After largely walking all over the team, Impy realizes regular earthlings maybe don't have powers, so he might be "the most powerful man on earth!" Cue reign of terror, or at least reign of annoyance, until Reed realizes attention is what Impy really wants, and getting ignored is his Kryptonite. News reports advise the general populace to do the same, until the Impossible Man gets so bored he leaves earth. The final page montage of regular people not giving him the time of day was kind of the best of the book! Marvel does these every so often; I wonder how many times they've put a new coat of paint on this one...
