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. It 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.

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.
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.
