Hitmontop debuted in The Mystory Is History. Butch gave a headband invented by Professor Namba to him, which made Hitmontop angry. This allowed him to hone his skills and made him unstoppable until the headband stopped working. Hitmontop used this headband again in A Parent Trapped! and A Promise is a Promise, where he was used by Butch to battle Ash and Sparky as well as Jessie and James in order to stop them from taking back the captured Lugia.
