This is Ember (Thanks partially to a suggestion from Urban Vanguard, his civilian name is now Aiden Ignatius. Now does anyone have a better idea for a superhero name besides “Ember?”) He was a college student when got his powers in some kind of scientific accident at a lab where he was an intern. He can fly, and can summon and manipulate fire. He is self-trained, and was recruited by the Warrior after the Warrior grew suspicious of him (the lab happened to provide materials to the Warrior.)
Ember is, outwardly, the most laid-back member of the All-Stars, and frequently quips to hide his deeply rooted insecurities and anxieties.
