This weapon is used by Ashrah in Mortal Kombat: Deception, Unchained and Armageddon.
Ashrah believes that the Kris is blessed and by slaying demons, Ashrah would become more humane and would be able to leave the Netherrealm. Though Nitara and her vampire race consider this to be a curse where it corrupts the wielder into thinking they were using it for a greater meaning.
It has been revealed that the blade Ashrah wields is a sinister creation known to the vampires as Datusha. It had slain many vampires in the past.
In Armageddon, Kreate a Fighters can select Kriss as a weapon if the Swords weapon type is selected.
In Wonder Woman's ending in Mortal Kombat vs. DC Universe, she's seen wielding a Kris, possibly Ashrah's.
In Deception's Konquest mode, Shujinko can find Ashrah in Edenia and she will tell him she has lost her Kris and asks Shujinko to find it. The sword is located in the Netherrealm.
The Kris bears a resemblance to the Dragon Sword used by Liu Kang in Mortal Kombat 4 and Mortal Kombat Gold.
