Honestly, X-Men #111 is one of the best Claremont issues so far.
I don’t know why it’s so good, it just is. It’s basically a done-in-one (although technically it’s part one of a Magneto story), where the Xers have been hypnotized by Mesmero into circus freaks and the biggest X-freak, blue hairy Beast, has to save them.
In the end, the team shakes off Mesmero’s influence.
Complete with big Magneto cliffhanger.
