10/10 Iron Man Stole A Lock Of Thor’s Hair In The Early Days Of The Avengers
Iron Man is an engineer, first and foremost. He’s all about solving problems in the most efficient manner, which isn’t always the best for the people around him. Iron Man’s been known to keep secrets and one of those eventually leads to Bill Foster’s death.
In the Avengers’ early days, Iron Man stole some of Thor’s hair and kept it for cloning purposes. This secret wouldn’t come back into play for years until Iron Man, Reed Richards, and Hank Pym created a cybernetic Thor clone. Unfortunately, the clone didn’t have the mind of the actual Thor and struck Bill Foster with lethal force, killing him.
9/10 Xavier And Moira Sent A Secret Team To Krakoa To Save The Original X-Men
The story of the All-New, All Different X-Men became legendary. After losing the first X-Men team to the vampiric mutant island Krakoa, Xavier recruited a new team to save his old students. What people didn’t know for years was that this was the second team Xavier had recruited. When Cyclops came back to warn Xavier about Krakoa, the two first went to Moira MacTaggert for help.
Moira was training young mutants Darwin, Petra, Sway, and Vulcan, who no one knew was Cyclops’s brother. Cyclops led this team to Krakoa, but the island seemingly killed the four of them. Xavier erased Cyclops’ memory of this mission, then sent him to try again with the team fans recognized. Having survived by merging with Darwin, Vulcan returned years later, attacking the X-Men to get his revenge for being left behind.
8/10 Moira MacTaggert Revealed Her Secret Mutation To Xavier Years Before He Formed The X-Men
Moira MacTaggert had a huge secret herself, one she revealed to Charles Xavier the first time they met at Oxford. Moira was a mutant with a unique power: every time she died, she reincarnated as herself with all the knowledge of her past lives. In her nine previous lives the same thing had always happened: humans had destroyed mutantkind.
Moira and Xavier let Magneto in on their new secret and together, the three of them worked in the shadows to create a nation for mutants. Using Krakoa as a base, the three turned the living island into a powerful nation, one where Moira’s very existence was a secret. However, she had her own purpose on Krakoa, as she was working to recreate a mutant cure she had made many lives ago.

6/10 Namor Was A Mutant All Along
Namor is the most powerful aquatic hero in the Marvel Universe and first made himself known to the surface world in 1939. Namor was an enemy of humanity during this time, constantly fighting the Human Torch and trying to destroy New York City. Once WWII started, he joined the fight against the Nazis, and he acted as both a hero and villain in the ensuing decades.
For years, everyone thought Namor’s powers came from his half-human/half-Atlantean heritage, but this was only half correct. Namor’s parentage caused him to become a mutant, which then granted him his powers and made him one of the oldest mutants on the planet.

Wolverine was once James Howlett, born to a wealthy 19th century Canadian family. His family was attacked by the groundskeeper the night his powers manifested and James killed the attacker.
From there, James’ travels took him to the Canadian outback, ending when he accidentally killed his friend Rose and went feral.

However, the demons of Amenth attacked the ancient mutant nation. The fighting was fierce, but Genesis and her children figured out a way to stem the tide.
Okkara was broken, with its armies embarking to battle the Amenthi on their home turf in Otherworld. Apocalypse was left behind to create a powerful army to battle the demons upon their return, which fueled his survival of the fittest beliefs.
3/10 The Inhumans Hid Themselves From Humanity For Millennia
The Inhumans’ lore stretches far back into Earth’s history. The Kree came to Earth in the distant path and experimented on humans, making them susceptible to mutation by the Terrigen Mists, a mutagenic catalyst produced by crystals the Kree left behind. The resulting Inhumans built a civilization, one they eventually moved far away from the humans.
