This article is about a/an planet in the Power Rangers franchise.


Onyx is a planet where the evil elements of the universe hang out.



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; Andros wore a simple cloak to hide his face, while Karone disguised herself as her former identity Astronema).

Onyx is also a running theme throughout the entire Power Rangers series as a planet where lost things usually end up;

  • 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.

Onyx Tavern


A town on Onyx

The Onyx Tavern is a monster bar on Onyx where monsters usually hang out. It was also where the auction of the Pink Quasar Saber was. Familiar monsters are seen in its episodes appearances alongside some generic patrons.


  • It seems Onyx is a place where minions of villain groups go to get away from their bosses, due to how much they fear being around them. When Karone pretended to be Astronema, she managed to scare the auction crowd into letting her have the Quasar Saber.
  • Onyx appears in more Power Rangers seasons then any other planet except Earth.[Citation needed]
