Speeda Demon's known history begins with Breakout. He is one of the villians who escaped from Hero Factory Lockup. At some point earlier in his history, he stole the design for the Furno Bike, allowing him to build his Nitro Rocket Bike.
After escaping from lockup, Speeda Demon went to Kollix IV. Preston Stormer was assigned to catch Speeda Demon. A bike race ensued, with Stormer on his Ultra Mark Speed Cycle and Speeda on his Nitro. Stormer launched some of his Jet Drones after Speeda, who goes under a overpass and causes the Drones to crash.
Stormer used the Drones as a distraction and uses it to get ahead of Speeda, turning him away from his origanal goal. Speeda then shots down an icicle, which lands on Stormer. While Speeda Demon is monologing, Stormer frees himself and the chase resumes.
Stormer threw his cuffs at Speeda and one end caught his arm. The other cuff atempted to catch the othe hand, but it got the bike's handle. Speeda spun out of control and was returned to lockup.
Speeda got his bail paid by and anonymous donor, and he was released. As soon as he was out of site from Hero Factory, he was jumped by a small group of cloaked figures. He then disapeared without a trace.
Speeda Demon wields twin swords. His helmet is identical to Black Phantom's. He rides a Nitro Rocket Bike.
