Joltik first appeared in BW041: Reunion Battles In Nimbasa! where it went up against Georgia's Beartic. Due to its small size, Joltik was very nimble and was able to outspeed Beartic's attempts to hit it with Rock Smash before attaching itself to the Freezing Pokémon and hitting it with a direct Thunderbolt. However this move backfired as Beartic collapsed backwards onto Joltik, knocking it out.
