Ruby was notorious for being a traitor as well as Tanya is in the games, betraying all her allies for the likes of Shao Kahn. It is assumed that Ruby may have been the killer of Jax's grandfather, as she states that she "took care" of him before he died.

In the series Defenders of the Realm, Jax meets Ruby who is secretly working as one of Kahn's agents. She tries to find out the location of the Earth warriors base, Jax then finds himself captured Ermac's forces and is held captive by the Emperor were he received numerous torture by Kahn's Shadow Priest. Jax's allies came to his rescue but were shortly outnumbered by the Emperor's troops and they too were captured. It seemed that their destruction was inevitable, but at this moment Ruby decides to help the Earthrealm warriors escape by leading them through an hidden exit.
