Finally. My brother done it and gave Riolu some Facial Expressions. Same rules applies like the regular rigged riolu model. Except you have to credit Valforwing, CherrySan94 & Me. And you aren't allowed to edit the facial textures unless you are going to recolor all of them.
If it doesn't hurt, will you fav or let me know if you downloaded
Edit: The facial expressions will be constantly updated faster then you can say. "Hey look at that Riolu beating up a lucario."
