Poliwrath looks superficially similar to Poliwhirl. However, it has gained more muscle, especially around its arms, which are now quite thick. In addition, it is much larger, standing a foot taller than its pre-evolution. Its eyes have changed from having wide pupils to small ones and it appears to sport a permanent scowl. Its belly also now resembles a gaping mouth rather than being completely circular, but retains the white coloration and spiral it had as a Poliwhirl.
