Marowak

Marowak has, by far, the highest Attack stat in the game with a Thick Club equipped. Furthermore, it gets access to Swords Dance to instantly hit the 999 Attack cap and a STAB Earthquake to run off that impressive Attack stat. However, Marowak is very frail and very slow, and despite its impressive attacking strength, it still fails to guarantee OHKOs against several prominent threats even after a Swords Dance boost. Therefore, a lot of prediction and team support is required to get Marowak to perform well on a team. However, when everything does come together for Marowak to work properly, it can single-handedly demolish the opposing team.
