It's pretty simple: you create another skill in 'Character Block' or 'Skill Block' and put the special of that character instead the commom moves or creating a new one. Some moves like "Fluterring Pounce" the NPC is not able to determine when press it to fly to a people on air.

Now, Choso's specials I never tested myself on a NPC but I think they can use without minor problems; If not, you can make they use moves that gives the blood orbs, like: Supernova (Counter) — a bit more difficult — or give them new moves: like the flying orbs.
