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.
Gulpin first became available in Pokémon Ruby and Sapphire. It is No#316 on the National Pokedex and is Poison-type. It is a green gas bag with pursed lips, slitted eyes and puffy hands. It also mounts a yellow 'feather' on its crest. Virtually, its whole body is its stomach. It can easily swallow anything its size, and more. It's stomach contains a special fluid and enzyme that dissolves anything, even scrap iron. Whilst digesting, vile, overpowering gases are expelled. It can evolve into Swalot, a bigger purple version of Gulpin, at level 26.
As a Poké Ball Pokémon
When summoned, Gulpin will stay 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 Pokemon. 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.
