Pyro is a member of the Brotherhood of Mutants.

Biography
Pyro brought Avalanche to Muir Island as Mystique had a job for them. The duo decided to kidnap Dr Adler for ransom, but when Pyro found Adler was Mystique in disguise, he deduced the doctor's cure was just a ruse to turn mutants into Apocalypse's slaves.

Pyro would re-appear as a member of the Brotherhood during their assassination attempt on Robert Kelly.
