The X-Men have been around for sixty years, growing from the least popular Marvel franchise of the Silver Age to the bestselling comics ever. There are numerous reasons for this, but a big one is all the great lore created for the comics. Amazing writers and artists have worked on X-Men comics, and created concepts and characters that have blown readers' minds. The X-Men's history can get pretty convoluted, but fans of the team look past that because of how much they love everything about the team.
