This Galvantula is a Bug/Electric-type Pokémon owned by Teaque.
Biography
Teaque, during the theft, used Galvantula to fight against Ash's Pikachu. As a precaution, Teaque's Galvantula redirected one of Pikachu's attacks to an antenna, disabling the security system, allowing Vanillite to take the gem. However, Pikachu used Iron Tail and defeated Galvantula, allowing Ash a victory for the tournament.
