Hmm. If we were to get a rival, it would probably be an actual character rather than a trainer class, and it would likely be Blue, Silver, or the newest main rival (let's just say Hop for now).
- Blue's team hasn't changed much, but assuming no starters since Red already has that covered, he'd have Alakazam, Aerodactyl, Arcanine, Gyrados, Machamp, and Exeggutor to choose from.
- I feel like Silver wouldn't get picked because Crobat is kind of a must, and it would be extremely difficult to implement him since he's always flying and has pretty rigid limbs. They might could make him an assist of some sort though. His other Pokémon would likely be Sneasel, Megneton, Gengar, Alakazam, and the three starters.
- I feel like Hop would just have Zacian and Zamazenta, with Wooloo as a taunt character.
There are some interesting choices here, but I feel like they would be better as Pokémon Trainer alternate costumes.
