Greninja, like its previous evolution, has the body style of a frog. In this form, it now resembles Toxicroak and has gained the appearance of a ninja. It is dark blue in color and has its tongue wrapped around its neck like a scarf.
It creates throwing stars out of compressed water. When it spins them and throws them at high speed, these stars can split metal in two.
Greninja is the final evolution of the starter Pokémon Froakie, and evolves from Frogadier at level 36.
