Guests are always welcome. Scorpion is a guest in Injustice. Red Sonja would probably be the best guest MK have ever seen. She wasn't voted sexiest female in comics for no reason. I'm just saying there are a lot of ninja women in MK. Keep some of them dead. Red Sonja is a barbarian. She would play completely different to other females. She's very original and well established. She will be a welcome addition, she may even take top spot for females.
Just make this character like Red Sonja. Zara is a non-canon character that makes an appearance in the animated series Mortal Kombat: Defenders of the Realm and was voiced by Nancy Linari. She was a female human-looking Amazonian warrior who served as the ruler of her own realm.
History
At some point, her home dimension was conquered by the armies of Shao Kahn and incorporated into Outworld. She would form an alliance with Princess Kitana and Ramath, the Keeper of the Crystal Realm, in order to bring about an armed rebellion against Shao Kahn's forces. However, she would betray her comrades in order to gain the Swords of Ilkan during the fighting which resulted in the death of Ramath and Zara's banishment.
She would spend many years and lose many of her warriors in finding one of the Swords of Ilkan. She would later fight against Princess Kitana once again and her Earthrealm comrades. After capturing Jax in a life draining sphere made by her Sword of Ilkan, she demanded that Kitana find the remaining sword so that she could be the undisputed ruler of the realms.
After Kitana recovered the second sword, Zara and her would engage in personal combat, but when she started to lose, Zara attempted to make use of one of the Swords of Ilkan but was defeated. Kitana opened a rift into the Void and banished Zara into that realm.
Background
Zara was a skilled warrior and military commander but one that was obsessed with the acquisition of complete power. After she was banished and defeated by Kitana, she developed a great deal of enmity for the Princess of Edenia
This could e her arena. Northern lights. Seeing as she's a sorcerer kind of. So a different coloured sky would go well
