Sparky was one of four comics fans approached at a convention by the Silver Ghost and recruited to be a part of his super team, the Crusaders. Sparky was given powers approximating those of an old comic character (and his name) and he and his partners, on the orders of their leader the Americommando, attacked the Freedom Fighters. They ceased their attacks when they found out the Americommando's true identity, and their powers seemingly faded quickly thereafter.
Sparky could control and generate flame.
- This version of Sparky (Earth-One), including all history and corresponding appearances, was initially erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths limited series. However the ending of Convergence retroactively prevented that collapse, saving all the alternate realities, though in an "evolved" form. Even though versions of the character may have since appeared, this information does not apply to those versions.
- Like his fellow Crusaders, Sparky was analogous to one of Marvel Comics' super team The Invaders, in this case Toro, partner of the original Human Torch.
