Ninja Nexus Prism

The Ninja Nexus Prism is an acient artifact that contained six legendary stars known as the Ninja Power Stars, originally from the legendary and powerful Ninja Nexus Star. It was covered in Ninja Steel before crashing onto Earth. It came to Earth seeking those who can defeat evil. It crash landed in the back yard of the Romero Farm, probably seeking Dane Romero, a Ninja Master.

It was being pursued by the evil champion known as Galvanax, who sought the Ninja Nexus Star to absorb its power and use it to take over the Universe. Dane used his sword to split the star into six fragments, forming the six Ninja Power Stars used by the Ranger team. As a result, an explosion occured, suriously injuring Dane. The Prism captured his spirit and healed him, but to Galvanax and his followers, as well as his own sons, they believed Dane was dead.

The metallic crust encasing the Prism, Ninja Steel, can be used to create new Power Stars, as used by Mick and the Rangers to add to their arsenal of powers and Zords. The Prism joined the Rangers in the final attack against Galvanax. As a result of using all of its energy to destroy Galvanax, the Prism dies, causing the Ninja Power Stars to reduce to dust, as they cannot exist without the Prism's power (this might not apply for Ninja Super Steel).

Madame Odius would later revive the Prism in an attempt to turn it evil and forge Dark Power Stars, but Brody thwarted this, and the Power Stars were restored and more powerful than ever as they were made of Ninja Super Steel. After Madame Odius was destroyed, the Rangers returned their Power Stars, and the Prism reconstituted them back into the Ninja Nexus Star. The Prism encased itself in Ninja Super Steel and set out for space, in hopes of saving another planet.
