[[caption-width-right:350:Our... hero.]]
I-Ninja is a quirky action video game made for the GameCube, {{Xbox}}, {{Playstation 2}} and PC. In it, our hero [[ExactlyWhatItSaysOnTheTin (named]] [[EveryoneCallsHimBarkeep Ninja)]] is exposed to a gem named a Rage Stone and accidentally kills his Sensei in a fit of rage. He then goes off in search of the other Rage Stones, fighting and commanding giant robots along the way, meeting mermaids, mystics and eventually going off to the moon in search of these artifacts.
!! The ''I-Ninja'' video game provides examples of:

* ActionGirl: A few of the ninja masters are women.
* BattleAura: Whenever Ninja uses one of his abilities, he gains an aura. Taken to the extreme with his final ability, [[TitleDrop I-Ninja]], which is essentially his aura turned into a ''death zone.''
* BigOlEyebrows: Just check out his picture up there.
* BlackSwordsAreBetter: The swords get the same color upgrades as the belt, so the best sword in the game is black.
* BloodKnight: Oh yeah, Ninja.
* CallingYourAttacks: Oh, yeah.
* CharacterLevel: A dual example. After finishing missions, you gain a token which goes towards your belt's colour. Once you have enough, you gain access to new areas. Your sword, after killing enough enemies, will become more powerful as well.
* ColourCodedForYourConvenience: The different abilities give Ninja a different BattleAura.
* ExactlyWhatItSaysOnTheTin: Ninja and Sensei.
* EveryoneCallsHimBarkeep: Again, Ninja and Sensei.
* EveryJapaneseSwordIsAKatana: Played with; Ninja's sword goes through a variety of forms, but it's initial one is a katana.
* EvilLaugh: Ninja's not evil, [[BloodKnight but he does let out nasty chuckles when he's tearing through many enemies.]]
* EvolvingWeapon: Ninja's swords.
* HeyItsThatVoice: Creator/BillyWest voices the titular hero.
* HumongousMecha: The first boss battle has you engage in a fistfight with one of these after repairing your own mecha over the course of the first level.
* KatanasAreJustBetter: Ninja's sword upgrades many times over the course of his adventure, but its basic form stays that of a katana for the entire game.
* LargeHam: Ninja himself.
* LovableCoward: Twiggy, the ninja master of camouflage.
* MacGuffin: The Rage Stones.
* MechaMooks: Pretty much the entire Ranx army.
* [[SeanConneryIsAboutToShootYou Ninja Just Threw A Bunch Of Shuriken In Your Face]]: See page image.
* NinjaPirateRobotZombie: One uncommon enemy is basically a robotic dragon/wolf hybrid.
* SpiritAdvisor: Sensei, despite being quite dead, stays with Ninja and acts as his mentor.
* TheBerserker: Ninja, to the point that the ''first'' ability he gains is called 'Ninja Beserker'.
* TitleDrop: Ninja's final special ability that allows him to kill enemies without even touching them!
* HubLevel: After a boss fight, you gain access to a new area and a new set of levels.
* UnexpectedShmupLevel: Several.
* UnexpectedGameplayChange: To the point that you actually begin to expect them.
* UnstoppableRage: Pretty much all of his special moves are fueled by rage and allow him to cut through entire groups of enemies like they were made of tissue paper.
* WhatMeasureIsANonHuman: If Ninja was fighting human enemies this game would have easily gotten an M rating for violence.
