Gulpin (ゴクリン, Gokurin, Gokulin in original Japanese language versions) is a Pokémon that appears as a Poké Ball Pokémon in Super Smash Bros. Brawl. It eats a close opponent and inflicts major damage before spitting them out. If no opponents are around, it will remain sitting until one comes within its range. While someone is inside Gulpin, other players can attack them, thus increasing the damage greatly.
Gulpin appears in "Super Smash Bros. Brawl" as a Poké BallPokémon and when summoned, Gulpin stays where summoned. If an opponent should come within range of Gulpin, it will open its mouth wide and swallow them. They will receive damage according to the amount they are contained in it. You can also inflict damage to the opponent inside by hitting the Pokémon. They will be abruptly spat out in a few seconds.
The attack cannot harm the user. If playing as the Ice Climbers, if Popo is swallowed, the Ice Climbers will desynch and the player will be able to directly control Nana until Gulpin releases Popo.
If a character is swallowed by Gulpin while Captain Falcon uses his Final Smash, Blue Falcon, on another character besides the one swallowed by Gulpin, Gulpin will disappear and the character that was swallowed by Gulpin will be seen in their T-Stance during the duration of Blue Falcon.
