Ashrah is a repentant demon hunter in the Mortal Kombat series, introduced in Mortal Kombat: Deception. Despite her demonic origin, she possesses a holy kriss that grants her angelic powers while allowing her to purify her soul by slaying more of her brethren. Her name is likely a reference to the word "asura".
Prior to her Mortal Kombat 1 redesign, she sports a purely human appearance with an elegant white outfit. In the original timeline's games, she fights with not only her kriss, but also with the martial art of Chuō Jiǎo ("Poking Foot"). In Mortal Kombat: Deception, she also fights with Bāguà Zhǎng ("Eight Trigram Palm").
Although she fights for the forces of good, Mortal Kombat: Armageddon plays on the "holy warrior" aspect by turning the kriss into a cursed blade that corrupts its wielder to commit genocide against vampiric and demonic species in the belief of a greater good. This puts her at odds with the vampire Nitara.
Although she does not appear in the series' alternate timeline, she later appears as a playable combatant in Mortal Kombat 1 with a slightly more demonic appearance (likely due to the game being earlier in the timeline) and reworked abilities (focusing more on her swordplay and powers both holy and demonic).
Ashrah was once a member of sorcerer Quan Chi's Sisterhood of Shadow, defecting after being sent outside of the Netherrealm and witnessing the tranquility of other realms. In response, Quan Chi sends some of the other Sisters (later revealed to be Kia and Jataaka) to hunt her down and kill her. While escaping, Ashrah finds a mysterious kriss and uses it to kill her pursuers, discovering that destroying demonic beings with the weapon was cleansing the evil from her soul. She then makes it her mission to purify herself, believing that with enough soul-cleansing, she would be freed from the Netherrealm.
She spent an untold amount of time slaying demons, eventually encountering a young Shujinko, who she trains on demon-slaying techniques. She eventually transcends, emerging in an unfamiliar celestial realm whose beings of light has made her into their chosen warrior.
She emerges in the forgotten realm of Vaeternus and begins exterminating the realm's vampire race, where it is revealed that the kriss is actually the cursed vampire-slaying blade Datusha, which corrupts its user to carry out genocide against vampiric and demonic races in the belief of a greater purpose. She encounters the realm's heroine Nitara, who lures her out of the realm into Edenia, believing that an ancient power there can stop her.
Although it is unknown whether the conflict with Nitara is resolved, Ashrah eventually joins the Battle of Armageddon under the forces of Light. Like countless others, she was slain in battle.
New Era Timeline
In the timeline brought by Liu Kang's ascension to godhood, Ashrah appears earlier in the story in Outworld, seeking revenge against Quan Chi.
She encounters the spectre Noob Saibot and defeats him, purifying herself enough to earn her ascension from the Netherrealm. The kriss, however, remains in the Netherrealm for the next denizen.
Upon defeating Blaze, Ashrah is completely purified into a being of divine light, whose radiance soothed even the darkest of souls. She travels throughout the realms to pacify the wicked, ending up purifying the sorcerer who targeted her in the first place: Quan Chi.
