Bouffalant later appeared, along with Alder himself, when Ash and his friends met the Champion in person. Bouffalant was used to battle against Ash's Pikachu, who started off with Thunderbolt. However, Alder seemingly waited patiently and did not order a move. Pikachu used Iron Tail and Quick Attack, making Cilan think Bouffalant's fur absorbed attacks. Bouffalant was also hit by Electro Ball and everyone saw Alder was actually having a nap. Alder woke up and ordered Head Charge, but Bouffalant turned around and hit Alder himself. Bouffalant was angry, but Alder apologized and gave an apple to Bouffalant, who happily ate it. Later on, Alder sent Bouffalant to battle a rampaging Gigalith, but soon decided to get Bouffalant out of the battle, since Alder saw Gigalith had a nail stuck in its foot.
During the cosplay event, Ash picked a card. Ash saw Alder and remembered him having a Bouffalant. Ash managed to dress Alder and Pikachu as Bouffalant and succeeded.
As the winner of the Junior Cup Tournament, Trip faced Alder in the battle. Trip sent Serperior, who launched a Solar Beam on Bouffalant. Bouffalant took the attack, but Trip saw Bouffalant's ability was Sap Sipper. Alder just anticipated what Trip was offering, so Trip had Serperior use Dragon Tail on Bouffalant's belly. However, Alder reminded Trip he was the Champion and had Bouffalant use Head Charge, which defeated Serperior.
