It was first seen in Ash and Trip's Third Battle! in a flashback of Trip's. Alder used it in battle where it only used one move, Head Charge. Bouffalant later appeared, along with Alder himself, when Ash and his friends met the Champion in person. Bouffalant was used against Ash's Pikachu but Alder fell asleep during the battle causing Bouffalant to attack him.
