Forever Ninja

The Red Knight or Forever Knight Ninja is a robot member of the Forever Knights and was a member of the Negative 10.

Ben 10
He was defeated by Perk Upchuck, who spat his own shurikens right back at him. According to the Pop-Up version of Ben 10, the knight is a robot personally created by the Forever King, Driscoll, to be his bodyguard. He first appeared in the end of Perfect Day, and made another appearance in Ben 10 vs. the Negative 10 (Part 1) and Ben 10 vs. the Negative 10 (Part 2).

He battles by using ninja gadgets, like shurikens, twin swords, lightsabers, and machetes, and has enhanced speed. In the Ben 10: Alien Force video game, he appeared as the Forever Ninja, a fighter in several stages.

Omniverse
The Forever Ninja returned in Return to Forever. He is part of Joseph Chadwick's Forever Knight remnants. He fought Ben and Rook, but was defeated.

In Bengeance is Mine, he, along with Sir Morton and the Twin Knights, fought Ben and Rook in Pakmar's store, Loofah Emporium. After the store got destroyed, they disappeared.

He is also seen in An American Benwolf in London, but later heavily damages itself with the Proto-Tool but was salvaged by a now mutated Chadwick.

Powers and Abilities
The Forever Ninja has enhanced strength, speed, agility, stealth and battle tactics. He has an assortment of weapons, including energy swords and various shuriken and throwing projectiles. It also has a limited self-repair system to mend minor damage.

Weaknesses
Though formidable, the Forever Ninja is not invincible. Loud noises such as sonic booms or the large bell of the Big Ben Clock Tower can disrupt its systems. If the robot takes enough damage, it will shut down.

Its Artificial Intelligence (AI) is not as advanced as some of the other alien robots in the Ben 10 Universe. When holding the Proto-Tool, it accidentally shot itself in the chest due to holding it backwards.
