Actually, Misty getting her own spinoff would be nice to see. Misty is a very different character from Ash, so conflicts, story beats, and other such things would be more fitting for someone like her to get involved in.
Serena because I would like to see her continued on her during as a Pokemon Coordinator but this time in the Sinnoh Region as she wears different outfits just like Dawn and catching more Pokemon in her twam since she only got three Pokemon.
