Synopsis

Following their victory against Screaming Mimi, Abomination, and M.O.D.O.K., the Super Hero Squad welcomed Black Widow into their ranks. Unbeknownst to them, however, the woman before them was not who she seemed. In truth, she was Mystique, a spy dispatched by Dr. Doom with a singular objective: to pilfer the Infinity Fractals from the Vault.
