This Marowak is a ground-type Pokémon owned by Jeffrey.
Marowak first appeared battling against Jessie's Dustox in the fake gym Team Rocket made up in order to steal Pokémon. After using its club to reflect the Poison Moth Pokemon's Stun Spore, it used Bonemerang to hit it from behind (after it dodged it the first time). That gave the Bone Keeper Pokemon the opening it needed to KO the moth with a Bone Club.
