Random Top Times Superheroes Went Bad (30 items)

(#17) Thor
In Thor: The Reigning, Thor has taken over as leader of Asgard and has it merged New York City, in the process killing tens of thousands of humans and Asgardians. Although it seems like a utopia, there are factions working against him. This version of Thor was eventually revealed to be in an alternate timeline.
(#26) Sunfire

Sunfire, former X-Men and Big Hero 6 member, was laying in a hospital missing his limbs and powers. This is when Apocalypse showed up and offered to return his limbs and powers if he would become the new Horseman of Famine). Shiro accepts and attacks the X-Men with the rest of the Horsemen.
During battle he is defeated by the X-Men and Emma Frost attempts to free his mind from Apocalypse's control. Sunfire breaks free but still retains his Famine form.
(#8) Hulk
In an alternate timeline, the world is destroyed by a nuclear explosion that kills most of the world's heroes. The Hulk survives and using his Bruce Banner intellect and his every growing Hulk powers, takes control of the world and leads with an iron fist. He opted to go the the name Maestro and ruled over his kingdom called Dystopia.
(#12) Wolverine

Wolverine has had it harder than most heroes and for much longer. In the mid 1990s, Magneto does what we were all thinking and painfully strips the adamantium out of Wolverine's body. This, and a series of events to try and put it back in, caused Wolverine to regress into a more animalistic, feral, state. Also, they stopped drawing him with a nose- which is just insult to injury at that point.
Apocalypse eventually captures and rebonds the metal his Logan's bones but at the cost of him becoming his Horseman of Death. He eventually broke the spell Apocalypse had over him and returned, metal claws and nose, to the X-Men.
(#22) Havok

One of the most popular X-Men story lines of all time is Age of Apocalypse. In this alternate reality, Xavier dies before he can start the X-Men and that puts everyone on different sides of good and evil. Havok and Cyclops actually end up working for Mr. Sinister. Alex Summers is the more emotionally unpredictable of the two bothers and has violent outbursts while on duty as a Prelate.
When Cyclops falls in love with the rebel Jean Grey and starts releasing prisoners, Alex exposes his brother as a traitor. He eventually tracks the couple down and kills Jean.
But don't worry. Everything went back to normal eventually.
(#2) Archangel

While Angel was with X-Factor, his wings were crippled by the Marauder Harpoon during the Mutant Massacre. After the wings developed gangrene, Warren's business-enemy signed the documents to have them amputated. Grief stricken, decides to travel in his private jet. However, before the Jet explodes, Warren is whisked away by Apocalypse.
Apocalypse offers Angel the chance to get his wings back if he will serve as his Horseman of Death (noticing a trend yet?). Warren agrees and is outfitted with metal wings that can shoot razor sharp feathers and undergoes mental conditioning to make him all the more evil.
