While Ruby did not exist in the games, aspects of her character (most notably her red ninja outfit) bear similarity to and makes her resemble Skarlet, a glitch character who would later become a full-fledged fighter in the 2011 reboot of Mortal Kombat. She is also a traitor to her home realm of Edenia, much like Tanya, who would be introduced in Mortal Kombat 4.
