Kuroninja was an extra ranger for Super Sentai. He was very mysterious and tried to avoid Shironinger for some reason. He earned his place in the Super Sentai Rangers after completing the Ninja Trials and saving the Hanarangers. Kuroninja also had the ability to create shadows using his Kage Shuriken.
One day, Kuroninja was looking for something to do, when suddenly a dragon-like mecha attacked the city. It was very menacing, with a red orb at its centre and a single gold horn on its head. The name of this dragon mecha was Dragon Brutus, and it came from a dimension where the Zyurangers, one of the old Sentai teams, had lot, and Dragon Caesar was destroyed. Dragon Brutus shrunk down to Kuroninja's size so that it could fight Kuroninja fairly.
Meanwhile, Anti-Kuroninja was in the headquarters of one of his greatest allies, the Cyberninja Tech Company. Cyberninjas were robotic ninjas, however, they needed the soul of a ninja to work. Most Cyberninjas were made from dead ninjas, such as Swordblade X, made using the soul of Raizo Gabi of the Kibaoni Army Corps. The only way Cyberninjas could regain consciousness and not rebel orders is if the soul had the mind of a fighter, like Swordblade X. Anti-Kuroninja saw the attack from Dragon Brutus, and asked the head of Cyberninja Tech if he could go up close to research Dragon Brutus. The head said yes, and sent a Cyberninja to accompany Anti-Kuroninja in finding Dragon Brutus. The Cyberninja's ninja soul was found in the underground. Its last memory was protecting its master from a cave in while fighting alongside a Sentai team known as Maskman.
In an unknown area, a mysterious warrior was observing Kuroninja fighting Dragon Brutus, from the eyes of Dragon Brutus. He looked like KibaRanger, yet at the same time, had elements of DragonRanger. This new warrior was KibaDragon.
