Ninja (Arcade)

Ninja is one of the two playable characters from The Ninja Warriors.

Details
The Ninja is a android with a ninja motif, wearing a blue uniform. He is tied to player two and his gameplay is pretty much identical to the player one Kunoichi, attacking with a pair of kunais in close range and throwing shuriken to hit far away enemies.

Though the Ninja never appears in The Ninja Warriors Again, he was replaced with another Ninja-themed robot who's bulkier and stronger.
