10 Oldest Mutants In X-Men History

2. Apocalypse (Estimated Age 5000)

Namor might be listed as Marvel's "First Mutant", but En Sabah Nur is the character most often noted as being the first mutant in the fictional comic book universe. His name even means "The First One", to belabour the point a little.

Also known as Apocalypse, he's been one of the main antagonists not only for the X-Men but the whole of mutantkind since, like, forever, appearing as a bad guy in comics, video games and the awesome nineties animated series.

True to his name, Apocalypse's whole bag is that he wants to bring about the end of the world, with the help of his Four Horseman which usually involves at least one tragic, fallen X-Man who's been brainwashed by the grey-faced goon.

He's apparently not all that good at bringing about death and destruction, however, given he's been at it since the 30th Century BC. Dude's literally Biblically old, born 5000 years ago in ancient Jordan. He was supposedly the first person on Earth to possess the mutant gene, causing his lips to turn blue, his skin grey, and his people to abandon him.

Thankfully a nice bunch of folks called the Sandstormers take him in, instilling the whole Darwinian "survival of the fittest" philosophy and effectively raising history's greatest monster. X-Men history's, anyway. When his powers - basically every basic superpower you can think of - turned up, and he further augmented himself with Celestial technology from beyond space, he found he was essentially immortal and never aged. Which is probably why he still looks so fresh-faced.
