History: Unlike the rest of the core members, Chamber did not join Generation X as a result of the Phalanx attack on mutants. He was sought out by Professor Xavier and invited to the Academy.
When his mutant powers surfaced it was in the form of a psionc blast which blew away half his face and upper body, and crippled his grilfriend Lady Gayle Edgarton.
Upon arrival in the U.S. he was attacked by Emplate who wished to feed on Chamber's bone marrow. With the help of Generation X he was able to fight of Emplate. Later Chamber was captured, along with the rest of Generation X, when Emplate attacked with his group of enthralls.
Chamber had a semi-relationship with fellow GenXer Husk. She tried to kiss him once but he panicked and blew a hole in the girl's dormitories, she used her husking power at the last minute and was unharmed. After they decided to break up there was some awkwardness between the two but that is no longer the case and they are close friends now.
Chamber joined the X-Men along with his former teacher Emma Frost, aka the White Queen. He became the subject of intense media scrutiny when he embarked on a relationship with a popstar named 'Sugar Kane'. This ended within a short period of time. Jonothan left the X-Men and his current whereabouts are unknown.
