History
The past history of Michael Redstone of Earth-1121 remains unrevealed, but it is presumably similar to that of the Michael Redstone of Earth-712. As much of their histories coincide with one another.
At some point in Michael Redstone's history one of his world's governments decreed that super-powered beings were a threat to the status quo and to be destroyed. Inventing a bomb to destroy them all, all the members of the Squadron Supreme (and presumably every other super-being on Michael Redstone's Earth) were destroyed by its explosion, with the exception of Hyperion.[1]
