Most of us can agree that seeing a ton of old faces from the previous games was cool, but which characters that didn't show up would you have loved to see? And what returning faces were you happy to see return. Personally, I wished that N had showed up, but I still love that Colress was there.
I was hoping that all the past main characters would show up, Red, Ethan, Brendan, Lucas, Hilbert, Nate, Calem, Sun, Kris, May, Leaf, Dawn, Lyra, Hilda, Rosa, Serena, and Moon. I would have not minded at all if they had just turned everyone at the battle tree into all the playable characters or one from each gen and a rival from each gen.
I wish that some of the lesser known characters returned such as, Anthea, Concordia, The 7 sages etc. Also old rivals such as Barry, Bianca, Cherren, XY rivals etc. also Ash and Serena together.
Would have liked to see Jasmine. No particular reason really besides I just like her, she was my favorite gym leader, cute design, uses some Pokémon I like, also nostalgia because such good memories from the Johto days. Could have given her some story excuse like she wanted to check out the weird steel Diglett and Dugtrio variants and bring them back to Olivine, something like that.
I would have really enjoyed seeing some of the trainers referenced in the game. For example I remember Giovanni being mentioned on the Ula' Ula Nugget Bridge. I also would have liked to see Zinnia, after all I feel as though she could have brought something upon the whole 'Dragon Trial' which I felt was kinda lack-luster and shoved in there because "ITS A Pokémon GAME WE NEED A DRAGON BOSS SOMEWHERE!" and i swear to Arceus if there's another Looker mission
Well, I would have liked to see more of the previous gen characters in the overworld. Like Red and Green (Blue in the games, but somehow just Green to me due to the manga) were hanging around the Battle tree.
i wanted Caitlin to come back in sun and moon. i already envision her with more tropical clothing and sandals xD
I love them all! I'd love more cameos. Like they don't even need to be part of the story or have a fanfare. Just have them standing around with a line of text maybe. Especially those that would make sense that they travel from region to region. (Champions, player characters etc)
I really want to see some of the manga characters get acknowledged. Other than that, I want to see previous rivals after all their character development show up and give a quick battle. And of course, a champion who ISN'T Cynthia. Don't get me wrong, she's awesome, but so is Steven!
