Origin: The Maestro comes from an alternate reality where nuclear wars destroyed the world's heroes and most of it's population, leaving a barren, barely livable planet. While the few humans were trying to survive miles beneath the surface, the Hulk, driven insane by the radiation and power, built a city which protected people from the radiation. The Hulk renamed himself the Maestro and allowed you to live in the city as long as you did what you were told and gave him whatever he wanted. In Exiles, Maestro is defeated and his power is taken by Morph. This happens in 2099.
