Alright since we dont have much to speculate on, what is the one pokemon from each of ash's regional team that you think should come back for more development this series. An underrated or under written one, unlike charizard infernape etc
Kingler : Now it has a perfect excuse. It has a G-Max form.
Bayleef : I wanted to say Totodile so it can evolve but I can't have this full of his Water-Types. Meganium can add some much needed muscle to his Johto team.
Glalie : Glalie got benched after the Hoenn League and only teased in the Sinnoh League. It was the AG Kingler. Plus it is his only Ice type at the moment. Maybe Mega-Evolution???
Gible : Captured too late, didn't even get a gym match. Ash has experience with Garchomp. It would be a nice partner for Dragonite.
Oshawott : Marketability killed him. He should have evolved to at least a Dewott in BW. Burgundy and Cameron killed the rest of the line. If it wasn't for Dawn and Piplup coming and them wanting to make some rivalry going on, I believe Oshawott would have evolved by then.
Greninja : While I want Noivern to come back and actually win something, Greninja needs to come back to his team. I get the feeling like that is going to happen eventually. In a series that is so focused on giving Ash popular Pokémon, they can't pass up giving him the most popular Pokémon in the world again. Hey, maybe they can finally give him a Dark-type move. Farfetch'd already has 2.
Melmetal : It needs more than 2 moves. Plus it has a G-Max form.
