"Cpl. Miles "Blaze" Lewis has always been drawn to the flame, but it wasn't until he joined up with Raynor's Raiders that he put his pyromania to good use. He's seen his fair share of battles since then, and has never failed to bring the heat."
A pyromaniac, Lewis has seen his fair share of battles against both the zerg and protoss. Unlike many firebats, Lewis isn't a resocialized criminal, doesn't smoke, and dislikes the smell of napalm in the morning. He has had training for covert missions.
Lewis's infatuation with fire began in his childhood. Later in life, he had the opportunity to join Raynor's Raiders and fight for the future of the Terran Dominion. He hesitated, but when he learned he could become a firebat, that sealed the deal. His tendency for pyromania earned him the nickname "Blaze." After the fall of Arcturus Mengsk, Lewis joined the Dominion Armed Forces. He heard of the disappearance of Jim Raynor after the End War, and wondered what happened to his former commander.

In early builds of Tychus's Outlaws in Co-op Missions, Blaze's role was initially supposed to be filled by a hellbat/hellion outlaw, which would have been designed around the Druid class from World of Warcraft. In hellion form, it could heal allies, whereas in hellbat form it dealt damage. However when the number of abilities per Outlaw were scaled down to one, it was found that the hellion had too many abilities.
