A Hara-Kiri is a finisher introduced in Mortal Kombat: Deception.
A Hara-Kiri is an alternate finisher where the losing player would cause their own death by using an input combination similar to performing a fatality. While the player who's victorious will still win, the Hara-Kiri serves as a method of the losing player to be able to end the match on their terms instead of allowing the winning player the opportunity to finish them off.
- Kenshi is the only character in Mortal Kombat: Deception who performs the tradtional Hara-Kiri which involves self-disembowelment, while a Hara-Kiri is typically performed with a Tanto, Kenshi will use Sento to perform the Hara-Kiri.
- While the Hara-Kiri was introduced in Mortal Kombat: Deception, there has been suicide based finishers in other games in the Mortal Kombat series. A few examples of suicide based finishers include; Cyrax's "Self Destruct" fatality in Mortal Kombat 3 (and all ports) has Cyrax enter a code into his arm panel and subsequently explode, killing both fighters. One of Raiden's fatalities in Deception has him releasing a ball of energy and throwing it at his opponent resulting in both of them exploding from the energy burst. Cyber Sub Zero has a fatality where he enter a code into his arm panel and jump onto his opponent and grab them, the two freeze and quickly burst into shards of ice.
