Onyx
Onyx is a planet where the evil elements of the universe hang out. It is also where Joe and Lola Carter were born.
History[]
Conflict is not uncommon, but Onyx is mostly desired as a peaceful place where monsters can get together in a semi-neutral setting. The 'good guys' such as the Power Rangers are still unwelcome there, but many frequently show up in disguise in order to gather information (Andros and Karone have both done this in the past).
Onyx is also a running theme throughout the entire Power Rangers series as a planet where lost things usually end up;
- The key cards which contained the Psycho Rangers were found there.
- After Kendrix Morgan, the first Pink Lost Galaxy Ranger died, her Quasar Saber also ended up in the wrong hands on Onyx, until Karone got it back.
- Sometime after 2004, the Dino Gems of the Dino Thunder Rangers mysteriously ended up in Onyx, presumably by some criminal who knew a person on Onyx who could recharge them, only to be acquired by Broodwing in Power Rangers: S.P.D.
In Power Rangers: Operation Overdrive, Onyx was used as the base for Thrax and the 4 Corona Jewel-seeking factions.
