From Bulbapedia, the community-driven Pokémon encyclopedia.
Tucker's Arcanine (Japanese: ヒースウインディ Heath's Windie) was one of the two Pokémon Tucker used to battle Ash in Tactics Theatrics. It battled against Ash's Corphish and Swellow, and gave Ash a run for his money. Tucker's Swampert and Arcanine seemed like a perfect combination, taking advantage of its speed and Swampert's defense as stated by Brock in the episode. It is voiced by Chie Satō in both Japanese and English.
When it looks bad for Ash, Corphish and Swellow gain their fighting spirit and come back to win the match for Ash. It was defeated by a devestating Crabhammer from Ash's Corphish.
In the double battle, Arcanine's main target was Ash's Swellow.
