what is hara kiri in mortal kombat

In Mortal Kombat, a Hara-Kiri is an alternate finisher where the defeated player would cause their own death by using an input combination similar to performing a Fatality. Essentially, it is a self-fatality that a player can perform after being defeated in a match. Hara-Kiri finishers were first introduced in Mortal Kombat: Deception and have since appeared in other games in the series, including Mortal Kombat 11. The Hara-Kiri mechanic allows losing players to have the last word in a match and can be seen as a way to add more depth to the games finishing moves.
