The Top 10 Hulk Villains
Grew up reading comic books in the 90's. Marvel fan at heart. Hulk, the Midnight Sons, and Marvel's cosmic universe are my favorites.
No. 4: The Maestro

First Appearing in The Incredible Hulk: Future Imperfect #1 in December 1992, the Maestro is the Hulk from one possible future-timeline. Still possessing Banner's intellect and the merged green Hulk/gray Hulk body, this future version of himself is a Hulk completely corrupt with power. The heroes have been defeated and the world has been reduced to a wasteland. Only one city remains, Dystopia, and the Maestro rules it with an iron fist.
Bruce has long feared what would happen if the Hulk's rage ever went out of control. Ironically it wouldn't be the rage but the power combined with Banner's intelligence that would turn the Hulk into that which he always feared. Freedom fighters from the Maestro's dark future traveled back in time to retrieve the only one capable of defeating the tyrant, the Hulk from the present. Facing the Maestro shook Banner to his core and the possibility of the Maestro surfacing in the future helps keep Banner and Hulk on the straight and narrow path of the hero.
The Maestro is one of the Hulk's greatest enemies.
