Secret Masters of Villainy...

The whole thing was a scam.

Uatu's Final Onslaught framed Iron Lantern and Dr. Strangefate--two of Earth's most powerful champions--for horrible atrocities (particularly poor Hal during the much-reviled Emerald Crossing) and then assaulted time and space itself during the Zero Heroes storyline, though Uatu himself was discovered to be a pawn of the Extant Celestial. This didn't save the heroes from being erased from existence at the beginning of Zero Heroes.

Then, with only the various X-heroes and outsiders defending the main Amalgam universe, a world cried out for heroes. And it thought it got them.

The Thunder Squad appeared seemingly overnight, bringing the rising tide of villainy to heel and a cheering, relieved public into their hands.
