Get it?
About what you said though, i do agree that there should be a time delay when the CPU wants to do a HARA-KIRI, or else it would not be fair.

Well i think they should do it as often as they do fatalities. I mean in MKDA they only did fatalities on me only some times. So thats how i think it should be. I mean what reason is it to do it according to difficulty level. Difficulty is how hard the character is and how much coins you get, not seeing if you can kill him first or not. The whole object of the fight is to win whether you finish them or not. Besides if they give you only certain amounts of time to do it, does that mean you would want them to kill themselves all the time. That would get a little boring to watch time after time.

His question wasn't how do you spell Hari-Kiri, his question was what do you think about the computer doing Hari-Kari's against you. Don't waste space.

I think it's an excellent question that I had never thought of before. I personally think they should be able to do it, but no more often than they would do a regular fatality (like once in every 10 losses) I mean how often did the computer on DA or older MK games do fatality? not very. I don't think it will be a problem it will happen just very very scarcely.

Great question, though!

Theres hasnt been a lot of information released about Hari Karis, except for the fact they are in the game. I bet Hari Karis will follow a set of rules...

For example.

1) can only do a Hari Kari in the third round.
2) computer can only do them on medium or higher difficulty settings
3) etc...
