Bandanadee (I think) would be the only likely Kirby newcomer. Galacta Knight would be awesome, but he just doesn't have enough relevance to the series. King DeDeDe and Meta Knight aren't really villains anymore, but the only truly repeated villain I can think of is Nightmare, and he's pretty old now. Maybe Drawcia's sister?I forgot her name, but a sequel to Drawcia's game, Canvas Curse, is being made, so the sister may be in it. Bowser Jr. and the sister would both use artsy attacks, so I doubt they would both make it.
