I'm not quite sure what you mean by animated ones. I'd scale the sprite up to 125% each step, then repeat the tutorial's process until you've got the sprite at a size you like.
If you're looking for Bianca from Pokemon Heroes, I'm sure a fanmade sprite exists, but you could also just find a similar Lass sprite, splice on the 'points' from Latias's head, and recolor them to match the hair color.
I will try that for the sprites as for Bianca i tried looking for one but can't find one i need this for another game im working on idk what to do for the other one.
