X-Men: Professor X
Charles Xavier is the man that brings it all together. Without his vision, then there wouldn't be any drama or action as it sought out to live happily among humans. His vision attracted many others as did his natural ability to help others. This talent of his brought in many others like himself that would become the iconic X-Men. He gave his X-Men guidance, education, and most importantly he made them all feel accepted in a land that forsake them all for being different. It was that trait of his that made him a popular character in the X-Men universe. He was an incredibly smart man with a great drive and an even better heart but the shiny attribute of his may just be his great telepathic ability. He often uses a machine called Cerebro to enhance his telepathic gifts to search for his fellow mutants in hope of letting them know that they are not alone and don't have to be.
Charles Francis Xavier was the son of a nuclear researcher by the name of Brian and Sharon Xavier. Brian died in a horrible accident and Sharon went on to marry his friend Kurt Marko, and Kurt's son Cain followed him the Xavier's Westchester mansion shortly thereafter the marriage. Cain was a spiteful boy as he was bullied by his father, which Charles felt as his mutation began to emerge. Sharon died when the two were young as did Kurt in a fire at the mansion leaving the two stepbrothers alone. The money went to Charles, and even more anger went to Cain that turned to his hatred of Charles. By the time that Charles graduated from high school he had become bald from an unfortunate side effect of his mutation. Charles went to Bard University at the young age of sixteen and would later go to Oxford to continue his education. At Oxford he fell in love with a woman named Moira Kinross as the two had passionate discussions on genetic mutations and they planned to one day marry. The only obstacle in their eventual marriage was Moira's ex-boyfriend Joe McTaggert who disapproved of Charles and thought very little of him. Charles enlisted in the military to validate himself to Joe who was a corporal. Charles quickly became a legend of sorts as he was incredibly skilled in search and rescue missions in large part due to his mutant ability. However, Moira called off the engagement effectively devastating Charles. She had no explanation as to why she called off the engagement which led to Charles leaving the Marines and traveling the world. On his travels he came across a man named Amahl Farouk who was a mutant who had the power to summon forth the darkness in the souls of others. When confronted with this monster, Charles dedicated his life to to protecting humanity from evil mutants while also saving innocent mutants from human oppression.
Charles traveled to Israel later in his life where he met a man named Erik Lehnsherr, who was also a fellow mutant who would become Magneto. The two were friends at first who would constantly talk about mutants. Due to their different backgrounds and upbringings the two had conflicting ideas of how mutants could be in the future. Charles believed that mutants and humans could coexist but Erik did not agree as he believed humans would fear mutants and when they fear something they automatically jump to violence. The two teamed up in Israel against the villain Baron Von Strucker who was willing to set the terrorist group HYDRA against the world. After dealing with him Erik ran away with gold that Baron had sealed away in a cave and parted ways with Charles. The two had a tremendous amount of respect for each other but ultimately, they did not see eye to eye on the future of mutant-kind. Charles headed to the United States but en route he encountered the alien scout named Lucifer in the Himalayans. Lucifer's race had prepared an invasion on Earth, but with Charles knowledge of this he had to make sure Charles would not intervene. Thus Lucifer dropped a massive stone block on Charles and crippled his legs. Following this he went through some personal issues and did not know if life was worth it anymore. After finding his way once again, Charles went back to school at Columbia University to get his Ph.D. in anthropology and then went to London for his M.D in psychiatry. In London came across Moira once again who had married Joe McTaggert and became a renowned geneticist. The two even began to have talks upon the idea of founding a school for mutants.
Charles returned to the States where he would study mutation once again and during this time a friend of Charles, John Grey, asked for his help with his daughter Jean. Jean who had emerging telepathic abilities suffered a traumatic experience when she telepathically experienced the death of a friend. Charles aided her in her recovery, and also trained her in controlling her abilities. Charles later met an F.B.I. agent named Fred Duncan who was investigating the growing number of mutants. He told Duncan of his plan of finding mutants and locating them into his mansion as a base for them to hone their abilities for humanity's benefit. Charles at this time was with a woman named Amelia but left him when he had found a young mutant by the name of Scott Summers. She left in fear of the impending battles between Charles' group of mutants and Erik's group of mutants. Over the following months, Charles had used a machine called Cerebro that helped him find mutants to the likes of Scott Summers, Bobby Drake, Hank McCoy, Warren Worthington and Jean Grey. The group of mutants that he first found came to be dubbed as the X-Men. The X-Men would fight off fellow mutants who wished to do harm to humans and keep the peace between human and mutants.
