I-Ninja is an action video game developed by Argonaut Games and published by Namco. It was released for the PC, PlayStation 2, Xbox and GameCube (in Europe, the game was available only for the PlayStation 2 and PC). A Game Boy Advance version of the game was announced, then later cancelled.

The game starts with a Ninja in training (simply named Ninja), who comes to rescue his Sensei (simply named Sensei) from the Ranx sent by Ninja's arch-nemesis, Emperor O-Dor. Ninja saves Sensei by defeating the Ranx. Then, a creature comes to attack Ninja which he deals with easily. The creature then spits out a Rage Stone which Ninja touches and goes into a fit of rage and accidentally kills Sensei. Sensei comes back as a ghost and tells Ninja that there are more Rage Stones and with their power, he can defeat O-Dor. Sensei then sends Ninja to find the second Rage Stone in Robot Beach.

Ninja arrives in Robot Beach and is told to rebuild Tekeyama, a giant robot that guarded Robot Beach before Kyza came. Ninja rebuilds Tekeyama and starts to fight Kyza in which he defeats him. Inside Kyza, a Rage Stone is found and Ninja retrieves it. Like before, he is unable to control the stone at first, and dashes around the area before heading for the next level. The guardian of Robot Beach and creator of Tekeyama, Yang, thanks Ninja by opening the gate to Bomb Bay, the location of the next Rage Stone.

Ninja arrives at Bomb Bay and saves it from many of the dangers the Ranx have set up. Ninja then finds a submarine inside a giant bomb and fights the mechanical fish, Ventis for the next Rage Stone. Ninja then meets the guardian of Bomb Bay, Aria. If anybody saves Aria from something, she always rewards the hero with hugs and kisses, with Ninja being no exception. She then tries to hug and kiss him, while he struggles not to harm her with the rage stone's power. Ninja opens the gate and gets away from Aria, not before calling her a "fish lady" and walking off.

Ninja (I-Ninja) has not been a contender in any CBUB matches.
