The legendary X-Men were founded by Professor Charles Xavier, a mutant telepath who had spent many of his adult years studying mutation. Following an encounter, Xavier became determined to protect the world from the threat of evil mutants as well as foster a world that would enshrine peaceful coexistence between humans and mutants. He eventually decided to start a school for mutants and train them to be what would eventually become the X-Men.
Charles turned his father’s estate into Professor Xavier’s School for Gifted Youngsters. He constructed the Danger Room to test mutants, and developed Cyberno, a prototype mutant detector that was later replaced by a more powerful machine called Cerebro.
