Marowak

Marowak is an offensive juggernaut, thanks to its signature item, Thick Club, which doubles its average Attack, increasing it to amazing levels. In combination with its signature move, Bonemerang, which hits twice, Marowak can prevent several common Stealth Rock users from setting up by bypassing their Sturdy ability. Its Ground typing is also an important attribute because it gives it an immunity to Electric-type moves and a resistance to Stealth Rock. Sadly, its weaknesses to common Water-, Ice-, and Grass-type moves and its low Speed hinder it. Marowak is also easily worn down due to its lack of recovery and mediocre special bulk. Additionally, it's only viable with its Thick Club, further limiting its options in the metagame.
