“Astonishing X‑Men” #36
Mentallo is back. The long-time psychic-for-hire (he dates back to the early days of Nick Fury and S.H.I.E.L.D. and his working relationship with the Fixer) is now working for Roxon, one of the major (and malevolent) corporate players in the Marvel Universe. He’s on a ship bound for one of those places you don’t want to go, the appropriately named Monster Island. Roxon paid big bucks to Japan for the drilling rights to the island and apparently Mentallo is their key to pacifying the natives. Natives that stand over a hundred feet tall and breathe fire, or resemble prehistoric dinosaurs with radioactive shells.
Except he doesn’t see it that way and he doesn’t care anything about the others. (He seems a little off his game, possibly even depressed. Not a good thing for one of the most powerful psychics on the planet.) With the monsters under his mental control, he can do about anything, and that includes sending a couple to stomp Tokyo, and no one can stop him.
Well, except maybe the X‑Men, several of whom just happen to be in Tokyo at the time.
Note: Gotta check the last page: the real monster is pictured next to a billboard advertising a Godzilla movie.
