8. Professor X
Professor Charles Francis Xavier does put the X in X-Men and is the founder of the mutant group. Without him, there wouldn’t have been a place for mutants to turn to when they needed support, guidance, protection, and help.
He first appeared in the very first X-Men comic with Angel as a powerful telepath with the ability to read and control minds. In the wrong hands, this power could have been extremely dangerous. Fortunately, Professor X was on the side of good; a man who wanted the best in the world and equality for all. This is a character who has never fully faltered on the idea that humans and mutants can live side-by-side together.
While being a character for equality, he also pushed forward the idea that a disability doesn’t hinder. He’s a paraplegic in most of the comics, except when focusing on the timeline before his accident. Despite his disadvantages, he also has the intelligence to create technology. His greatest work is Cerebro, which tracks and detects other mutants, helping to locate more and bring them into the fold.
While Magneto is the Malcolm X of the X-Men world, Professor X has been viewed as the Martin Luther King Jr. He fights for equal rights and for mutants of all kinds (especially those who have physical differences) to live free and in harmony with others.
Despite his kind nature, he is also strict and just wants the best in people. Mutants know they can turn to him for advice and guidance, but he has rules that must be abided by, making him the perfect leader for the group.
