Fantastic Four vs the New Fantastic Four

With the real Fantastic Four seemingly murdered and monsters on the prowl, the alien skrull outlaw responsible for the mayhem used her low-level telepathy and shape-shifting talents to dupe four of the Earth's toughest heroes into action! Though this makeshift FF only lasted for one mission- just long enough to defeat the warring Skrulls, hold off the malevolent Mole Manand a million subterraneans, and defuse a multimegaton alien bomb - they certainly made an impression! And who knows - they might someday decide to add to their success and team up again! Fantastic Four #347 1990
