Sanpei is a character appearing in Pokémon the Series: XY.
Sanpei first appeared in A Rush of Ninja Wisdom! where it criticized Ash and Froakie at their training. He disappeared after that and when Ash found him again, Ash challenged him to a battle which he accepted. Ash used his Froakie against Sanpei's Frogadier. Frogadier managed to dodge many of Froakie's attack and at last defeated it.
After that Ash requested Sanpei to train Froakie for Quick Attack and Sanpei agreed. Using different techniques, he managed to teach Froakie Quick attack. He also defeated Team Rocket in the process.
Sanpei returned in XY052 with his newly-evolved Greninja.
