Saint Michael

Saint Michael is an archangel, the son of God and the brother of Satan. At some point over the past few centuries he was subdued and captured by Zinyak and forced to endure an advanced simulation in which he was stuck in an apocalyptic setting and fighting Satan over and over again. Zinyak hoped that bending an archangel to his will would help with his other plans to dominate the universe, but Michael managed to resist.

When Satan and his forces escaped Hell, the 3rd Street Saints busted out Michael from his prison and he fought against Satan in Downtown Steelport, eventually bringing down his brother and banishing him back to Hell.
