The Kris or Keris (misspelled as Kriss in the games) is a type of Southeast Asian dagger, often featuring a wavy blade. They range in size from the length of a small knife to that of a short sword. They were said to be magically infused during their forging, which was believed to grant some Kris supernatural powers. Communities such as the Javanese, Malays, and Balinese traditionally wore the weapon on a daily basis either as a status symbol or for self-defense purposes. It was the weapon of last resort for warriors who lost their primary weapon in battle.
Ashrah believes that the Kris is blessed and by slaying demons, Ashrah would become more humane and would be able to leave the Netherrealm. Although, 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 purpose.
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.
