The character
Greninja is the final evolution of the Froakie line from the Pokémon Kalos region, known for its ninja-like appearance and the Water/Dark typing. It is famous for its unique Battle Bond ability and its Ash-Greninja transformation in the animated series. Mega Greninja is a non-canon-to-games Mega Evolution concept used in the trading card game, depicted here as a sleeker, more aggressive-looking ninja form.
