Onyx

Onyx is a planet where all lost things in the Power Rangers Universe end up.

The Data Cards that the Space Rangers trapped the Psycho Rangers in ended up here where Deviot hustled them from a seedy merchant.

The Quasar Saber of Kendrix Morgan ended up on the planet on auction after the Pink Ranger died, but was kept from the hands of evil by Karone.

The Dino Gems of the Dino Thunder Power Rangers ended up on this planet 20 years after the team's final battle and was bought by Troobian mercenary, Broodwing who used them to bring Dino Rangers, Connor McKnight, Kira Ford and Ethan James to the future.
