Houndoom (Japanese: ヘルガー Hellgar) is a Darkness-type Stage 1 Pokémon card. It is part of the Plasma Blast expansion.
Dark Clamp's Japanese name is that of Jaw Lock, a move later introduced in the Generation VIII Pokémon games that Houndoom cannot learn. This card's Pokédex entry comes from Pokémon Black 2 and White 2. Grimsley's room in the Pokémon League of Unova is featured in the illustration.
