The first Pokemon we see Red use, Poliwhirl is a powerful water-type Pokemon that his notorious for obeying Red at every turn in their adventure. It has a multitude of attacks from belly-swirl, a kind of hypnosis that can put his opponents to sleep to water-gun, hydro-pump, and mud bomb. I'd like his voice to be slightly on the lower side in terms of pitch. He says only a few words, but each one has different meaning.
