Second born of the Pyro siblings, but the only failure in the process
to make them super powered, Mace has something of a failure complex.
That, and he's been stuffed into a suit that keeps him alive (Star Wars
is NOT one of his favorite series, any longer).
But, some stolen technology from the Lockharts (stolen as the Pyros ran
out of the hero side of things to the villain side), a few flame
emitters (hey, with a last name of "Pyro," what do you think you'd go
with?), he's doin' just fine.
