Gary's Arcanine (Japanese: シゲルのウインディ Shigeru's Windie) is one of Gary's strongest Pokémon. It is voiced by 三木眞一郎 Shin'ichirō Miki in both English and Japanese.
Its first appearance was in the Viridian City Gym, in the episode The Battle of the Badge. Gary sent it out to battle Giovanni's Kingler. Despite a type disadvantage, Arcanine came out on top and defeated the Template:Type2. However, both his Arcanine and Nidoking were defeated by Mewtwo, leaving Gary confused as to both why he lost and what Pokémon he had just battled.
Arcanine next appeared in Extreme Pokémon!, where he used it to compete in the Extreme Pokémon Race. Ash initially thought Gary was mistreating the Pokémon, but after learning that it wasn't hurt, he competed as well, subsequently defeating his rival.
It made another appearance during the Silver Conference against Ash's Snorlax. Despite Gary's efforts, Arcanine was no match for Snorlax, and was defeated by the large Pokémon.
