Sentry/The Void
The Sentry, aka Robert Reynolds, is one of the most powerful characters to ever join the Avengers. Although he is a hero, he is unpredictable and mentally unstable, which makes him very dangerous when you consider the amount of power he wields (he is described as possessing the power of “one million exploding suns”). In addition to super-strength, speed, and durability, he can fly, manipulate energy, and alter matter. He also has mental powers.
He has previously fought the Hulk in the comic books – most notably in the World War Hulk story arc – when the two fought to a draw, only after exhausting each other, and it would be fantastic to see them fight in live action (even though, in theory, the Sentry should annihilate the Hulk).
What makes the potential bout so intriguing, though, is the evil alter-ego of the Sentry known as the Void – a dark and powerful presence just waiting to be unleashed. In the comic books, the Void casually broke every bone in the Hulk’s body – wouldn’t that be a shocking thing to see as part of the Marvel Cinematic Universe?
And now we move on to the first monstrously powerful evil character on this list.
