8. Mystique
Hey folks, it's everyone's mom!! And that's only a little bit of a joke.
Interestingly enough, Mystique didn’t start out as an X-Men villain. Back when she called herself Ms. Marvel, she was a Captain Marvel villain. However, when Chris Claremont was writing both Ms. Marvel and X-Men, he decided to bring her and her adopted daughter Rogue over to fight against the Avengers and the X-Men.
Rogue eventually defects to join Nightcrawler, who was abandoned by his mother – Mystique – as a young child. Mystique’s other son, Graydon Creed, is a politician with anti-mutant leanings.
An unknown assassin eventually eliminates Creed, and it’s revealed years later that the assassin is Mystique. But it’s not the Mystique from that time; it’s a future Mystique who’s traveling through time to solve a paradox and…aaaaaaggggghhhhh, this is why people hate the X-Men. It's all just far too confusing.

7. Mastermind
Ah, Mastermind. He's not the most threatening X-Men villain, but he's definitely the easiest to hate.
Jason Wyngarde is a top-tier, mega-level d*****bag. Like, he’s The Worst. And because he’s a disgusting creep, he typically uses his illusion and mind control powers to manipulate women. As an early member of the Brotherhood of Evil Mutants, he creeps on all the women members until they actually disband.
After that, he heads over to the Hellfire Club, because that's where you go if you’re a supervillain who happens to be very kinky. While he’s with them, Jean Grey stops by, and Jason just can’t resist messing with her head. She freaks the eff out, becomes the Dark Phoenix, and eats a star.
Lotta deaths on your hands, Jace.

6. The Brood
The X-Men go to space a lot. Like, a lot, a lot. And of all of their alien enemies, I have to pick The Brood as my favorite.
They are terrifying. Clearly inspired by a little film called Alien, the Brood are insect-like monsters that lay eggs inside their victims. But, while the Xenomorphs just let people run around with those eggs, the Brood poison their minds and pacify them with hallucinations and visions in order to slowly conquer their minds and then rip their bodies apart. Yeah, they’re terrifying.
If you feel the need to read an incredibly scary X-Men comic, go pick up the Brood saga. That s**t will turn your hair white. The Brood stick around after their initial appearance, popping up in Captain Marvel stories from when the main character is Binary or Ms. Marvel. Also, one Brood member is a minor player in Planet Hulk.
Plus, in one story, they attack New Orleans, and the X-Men have to team up with Ghost Rider to kill them. That's a fun one.
