Gary's Electivire is a Pokémon Gary caught in the Sinnoh region.
Electivire first appeared when Ash returned to Pallet Town after becoming the master of the Battle Frontier. Electivire battled Ash's Pikachu and easily won. It then travelled with Gary back to Sinnoh and was used to help in Gary's studies with Professor Rowan.
Electivire also appeared to help Gary and Ash sabotage Pokemon Hunter J's ship. It's final appearance was when it battled Saturn's Toxicroak alongside Gary's Umbreon. Toxicroak superior speed and power allowed it to defeat both Electivire and Umbreon, a remarkable feat considering they were among Gary's most powerful Pokemon.
