Sanpei's Greninja first appeared as a Frogadier in A Rush of Ninja Wisdom! on the tree along with his trainer. When Ash challenged Sanpei to the battle, Sanpei decided to choose Frogadier as Ash's Froakie's opponent. Frogadier using its speed and attack dodged many of Froakie's attack. On its turn, it managed to defeated Froakie with only a few hits. Later it helped Froakie to try and learn Quick Attack, but Froakie ended up learning Double Team instead. He also defeated Team Rocket in the process.
