Gary is a member of Project Mew and heavily involved in Go's goal. We see him battle Moltres, Articuno and the new Regi's.
Iris became Unova Champion, Axew finally fully evolved to Haxorus and she made it to the Masters 8.
Serena struck out on her own becoming a star coordinator, will be involved with an idol duo with Lisia and she takes all of Ash's encouragement with her to heart. She now feels fully independent.
Lillie and her family finally found Mohn. Kiawe and Sophocles also got some nice spotlight. We see Kukui's baby born from the end of SM.
Brock is now a full fledged Pokémon Doctor, something we didn't quite get to see in his SM cameos. He also has Blissey and a Mega Steelix.
Misty has Mega Gyarados and is now portrayed as a stronger Gym leader than she ever was before.
Bonnie/Clemont didn't quite get any major advancement but he's still shown to he a strong Gym leader and Bunnelby evolved.
Dawn unfortunately didn't get any advancement here but we know she did 3 contest circuits off-screen and had major roles in villains and legendary plots. We saw her meet Cynthia, Brock and Ash again and her role in the Arceus specials was well done. She also had the first bond with Koharu. But she kinda got screwed over with no new pokemon or goal advancement.
Aside from MIA characters like May, Max, Tracey and Cilan, Dawn is the only one not to get a major advancement to her story so far.
I hope whatever they plan to do with Paul is handled well.
