Poliwrath

Poliwrath might look like just an average fighter with mediocre stats, but in reality, it is quite a formidable threat. A well-balanced stat distribution gives Poliwrath a few options in offensive and defensive sets, and a unique Water / Fighting typing grants it many useful resistances, while Water Absorb gives it a full immunity to Water-type attacks. These traits allow it to take on many of the most dangerous threats in RU, including Crawdaunt, Kabutops, Aggron, and Feraligatr. In addition, BW brought Poliwrath Circle Throw, a STAB phazing move which works extremely well on a bulky set. Even though Poliwrath is unable to excel in one specific role due to its all-around mediocre stats, it is certainly a Pokemon that has a solid niche in RU.
