History
Before V-Day, Pyro was part of the Brotherhood of Evil Mutants. Afterwards, he joined Blob's Brotherhood Traveling Circus and Carnival, where he used his mutant fire powers as part of his circus performance.[1]
Personality
Pyro is friendly and easygoing.[1] He also seems to be quite trusting, as unlike the other circus members, he never suspected that Clint was planning on going off-script or that anything else untoward was happening in the circus.[2]
