Politoed is a green, bipedal, frog-like Pokémon with yellow hands, belly, throat, and toes. It has a long, curled hair on top of its head and pink cheek spots that are smaller on the female than on the male. There is a green swirl on its belly. Its legs are well developed and it has bulbous toes and fingers.
Politoed acts as a leader to Poliwag and Poliwhirl, which gather from afar upon hearing its cry. Politoed likes to expand its throat and sing. When three or more assemble, they sing in a chorus with a loud, bellowing voice. The curled hair on Politoed's head is considered proof of its status as a king. The longer and curlier Politoed's hair is, the more Poliwag and Poliwhirl will obey it, and the more it is respected by other Politoed. Politoed lives by the water's edge.
Misty's Poliwhirl evolved into a Politoed in Outrageous Fortunes. This Politoed is very cheerful up to the point where it would occasionally lose focus in a battle and start clapping.
A Politoed, nicknamed Bean, appeared in I Politoed Ya So, under the ownership of Tammy, a young girl who uses Pokémon for cheerleading. It is distinctive from other Politoed by the red band it wears around its head. It had a falling out with Tammy, prompting her to ask Misty to lend her own Politoed to her for a while. Later, she and her Politoed made amends, and Tammy returned Misty's Politoed to her.
In Ampharos Amore, Silver borrowed Gold's Polibo in exchange for his Seadra. Due to the effects of the King's Rock Polibo was holding along with the trade between Silver and Gold, Polibo evolved into a Politoed. Later, he was returned to his original Trainer.
Politoed is a combination of polliwog and a corruption of toad. It may also be a play on 'poly-toed', meaning "having many toes", since, as Poliwhirl, its feet were digitless.
Nyorotono may be a combination of ニョロニョロ nyoronyoro (the sound of slithering) and 殿 tono (lord). This is possibly inspired by the トノサマガエル tonosamagaeru (dark-spotted frog), whose name literally means lord-frog in Japanese.
