Marowak

When people think of cavemen, the trademark weapon that comes to mind is the club. This powerful weapon was taken to a whole new level in the realm of Pokemon, where it can turn an average Pokemon with an average base 80 Attack stat into a monster with 568 Attack; the beast it creates is so powerful that it makes even Deoxys-A tremble in its wake. Yes, a small creature with a fossil on its head is transformed into a destructive force that is capable of shattering the very world as we know it; its name is Marowak. When equipped with a Thick Club, Marowak can deal massive damage. Its Defense isn't shabby either, maxing out at 350. But sadly for this demon from the past, its other stats are terrible, with the exception of its average Special Defense stat. However, this monster should not be underestimated; under Trick Room, it can truly thrive. Its pitiful Speed can be turned into an advantage under the twisted dimensions, thus making Marowak an exceptional candidate for a Trick Room team. It also has access to the EdgeQuake combination, gaining STAB on Earthquake thanks to its Ground typing. All in all, with Thick Club equipped, Marowak can be force to be reckoned with in the RU environment, even with its decidedly average stats.
