Ashe's Greninja

Barry's Greninja (Japanese: ジュンのゲッコウガ Jun's Gekkouga) is the first Pokémon Barry obtained on his journey with Ashe in the Kalos region.

Personality and Characteristics
Like Barry's Emboar, he is shown to be more serious than his trainer but is fiercely loyal to him.

Greninja seems to appreciate and respect those who show bravery and selflessness. As Barry is his trainer, he respects him even more so as Barry has shown these traits time and time again.

True to it's nature, Greninja moves with the speed and grace of a ninja, swiftly and silently without being detected.

Trivia
