I have a version of Hatsune Miku for Mugen Mortal Kombat Project that I made (The one with the battle plan and towers).
It's on an archive site that this forum has blacklisted. If you're interested in it, I'll make a mediafire link to it.
It haves 2 special moves, some combos, 2 fatalities, 1 friendship, 1 animality, 1 brutality, and a Hara Kiri.
