Coolidge became known as Central City's most notorious arsonist, ever since Mick Rory "went off the grid." At some point, he was defeated by The Flash and arrested by the Central City Police Department.
At Coolidge's trial, he glared at Cisco Ramon and Julian Albert when they made fun of his codename. Cecille Horton was the prosecution in his case. Barry went up to testify, but unknown to the judge and Coolidge, Barry had lost all of his memories. As such, he botched the testimony, and the judge allowed Coolidge to walk.
Upon his release, Coolidge was back to his old tricks, setting fire to a large office building. However, he was defeated by Barry, who had recently regained his memories, and Kid Flash, and was arrested again.
- Flamethrower: Coolidge used a flame throwing gun to commit his acts of arson. The gun was attached to a large backpack, which also held tanks of fuel to power the gun.
