In the anime, HeatMan first appears in season 2 of the first series. When FreezeMan's robotic penguins freeze all of DenTech City, Meijin, who create HeatMan, happens to be dining at WWW's curry restaurant.Later, a penguin freezes the group, but the heat from HeatMan's PET defrosts them. Meanwhile, Mr. Match's NetNavi, TorchMan, is severely injured by FreezeMan, and is rapidly being erased. Meijin then offers to save TorchMan by merging him with HeatMan. Match violently refuses at first, but later agrees to save his Navi. Later, MegaMan is about to be deleted by FreezeMan, but TorchMan, having been reborn as HeatMan and free of his chains, arrives and defeats FreezeMan with ease.
Later, towards the end of the series, while FreezeMan is attempting to capture Bass, HeatMan reappears and attacks FreezeMan for vengeance. HeatMan is overpowered, but Meijin calls and offers him to use his special code. Even though it's risky, Match agrees for the sake of revenge, and defeats FreezeMan again. FreezeMan is later deleted from his wounds.
HeatMan reappears in Axess, when VineMan spreads his plants throughout the Cyberworld. His plants attack the WWW Navis, and HeatMan is the only one who escapes. Mr. Match then tracks VineMan down to defeat him and free his friends, meeting Lan and MegaMan along the way. However, VineMan injures HeatMan, so he's taken to Mr. Famous to be healed. However, Mr. Famous realizes that TorchMan has been living inside HeatMan. TorchMan is revived, and with his help, MegaMan acquires Torch Soul. He and TorchMan then proceed and defeat VineMan.
