SparkMan appears randomly in the Den Battle/City Battle Tournament. His operator cheats to win by changing Lan's Folder in his PET to one with weak Battle Chips. But Lan fixes the problem with the help of JoMon's grandfather, the chief of JomonElec, who needs a 7 digit code (the code is 1563546). Later, SparkMan battles MegaMan in the Tournament, but loses. Afterwards, he and Terry get into a fight, blaming each other for the loss.
SparkMan appears as a Darkloid in Axess. His first appearance is when Lan, Chaud, Dr. Hikari, and Dr. Regal are studying one of Nebula's Dimensional Area Generators. Dr. Regal sends him to destroy the Dimensional Area generator, so that SciLab wouldn't uncover its secrets. Lan and Chaud Cross Fuse and try to stop him, but the generator drains their energy, leading to their defeat. SparkMan destroys the generator and escapes.
He later attacks a train network, but is deleted by MegaMan in Wood Soul.
He is later revived by Dr. Regal to distract the NetPolice, but is deleted by MegaMan in Roll Soul.
