Many years ago, a team of astronauts found a mysterious space dumpster. They opened it, releasing the evil sorceress Rita Repulsa. Because of this, Zordon, the entity who sealed her away, had to find five teenagers to combat the evil sorceress and her minions. Thus the Power Rangers were born.
However, before that happened, a team of astronauts found a strange container the exact same shape as the dumpster. They opened it, freeing the evil Witch Bandora and her evil minions. Five people from the prehistoric times were revived to combat Bandora as Kyoryu Sentai Zyuranger.
These two teams looked exactly the same, and as the years passed, other teams of Power Rangers and Sentai Rangers appeared, such as Shuriken Sentai Ninninger and Power Rangers Ninja Steel. However, Super Sentai was very advanced, having more teams than the Power Rangers. Fortunately, the two forces existed in separate universes...
In the Super Sentai Universe, a large portal opened. Out came a large army of soldiers. Kyoryu Sentai Zyuranger was somehow the team that found the portal, and they saw two villains they recognized. One of them was wearing gold armour. The other had a skeletal body, half of it had a camouflage pattern. They were Grifforzer and Gashadokuro. However, there was one leading the two villains and the other soldiers, who looked new to the Zyurangers. He looked like DragonRanger, except that his armour was more white. The shield he had was green, and his visor was red. TyrannoRanger, the red ranger of the Zyurangers, asked the mysterious villain "Who are you?" "My name..." the evil ranger said, "is KibaDragon, and this universe will be mine."
Meanwhile, on an artificial island patrolled by several armoured robotic ninja, an evil Sentai Ranger in grey noticed portals everywhere. Villains had arrived from the portals, including: Azald, an enemy of the Zyuohgers who was known for his blue cube-like design, Kibaoni Gengetsu, the arch-enemy of the Ninningers, and Chaos, an enemy of the Kyoryugers. The evil ranger, known as Anti-Kuroninja, was not expecting villains to appear out of nowhere, so he grabbed his katana and prepared to attack.
In another dimension, an evil mysterious villain was watching the entire thing. As he observed, he said "Everything is going according to plan. First, I revive the defeated villains of each world. Once I revive enough villains, it will be time for the second phase." The mysterious villain then opened a dimensional portal into the Power Rangers Universe.
