Under a cloud of increasing anti-mutant sentiment, Professor Xavier created a safe haven at his Westchester mansion where he could train young mutants to use their powers for the betterment of mankind. Xavier spent months recruiting his early students (code-named Cyclops, Iceman, Angel, and Marvel Girl), dubbing them "X-Men" because each possessed an "extra" ability normal humans lacked.
Cyclops: Reserved in demeanor, Scott Summers hid his emotions from others, just as his ruby quartz visor hid his destructive eye beams from the world. Unable to express his love for his teammate Jean Grey, he was nevertheless a skilled tactician, and was made deputy leader of the X-Men.
Jean Grey: Jean Grey was 10 years old when her mutant telepathic powers first manifested, allowing her to experience the emotions of a dying friend. Taken to Charles Xavier for treatment, she helped the professor fine-tune his Cerebro machine, allowing him to locate and assemble a team of mutants, with Jean at its heart.
Angel: Born into a wealthy family, young Warren Worthington's life changed forever the day he sprouted wings. While he hid them under his clothes at first, he soon realized the could help save lives, and he rescued his classmate form a fire while disguised as an angel. He was quickly recruited by Professor X.
Ice Man: Bobby Drake did not have an easy time coming out as a mutant. Persued by a lynch mob, he was only spared by the intervention of Professor X, who stoppped the mob and erased their memories of Bobby's ice-generating powers. At first, he coated himself with a layer of snow, but he later protected himself with solid ice.
