Part of Magneto's mutant army, Madison and his brother Lionel were seen as too insane to remain in plain sight, and were sent to the small Central American country of Santo Rico to keep them out of sight. There, the brothers ruled the human populace with iron fists, conducting extreme experiments on them.
Eventually, their rule came to an end when the Hood, a human criminal, and his army of super-powered humans sought to retake Santo Rico for their own gains. Madison was killed shortly after his brother Lionel's death.
