Raccrupt (Japanese: Neshoku) is a genetically enhanced Combat type Pokémon created by Team Rocket. Its gene bases are Raticate and Machoke.

Raccrupt's top-heavy physique causes the pokémon to travel on all fours, though it has the capability to move about using its two back legs. Despite its formidable appearance, it is fiercely loyal to its assigned work partners and exhibits a youthful energy and enthusiasm while not in battle.
