There's so many more moments they could capture in the Pokemon series. Here's what I'm thinking:

Kanto:
>Team Rocket raiding Silph Co
>Leaf exploring the Pokemon Mansion, exposition about Mewtwo's existence
>focus on Bill and fusing with Pokemon, then he gets a visitor: Lillie

Johto:
>Red Gyarados
>summoning Lugia or Ho-Oh
>Red scaling Mt. Silver, then suddenly a challenger approaches him

Hoenn:
>an episode focused on the Latis
>player character fighting Norman, their father
>Anabel noticing a disturbance outside of the Battle Tower and sees an Ultra Wormhole

Sinnoh:
>focus on another of those stat trainers? Like Marley
>a Darkrai episode
>an Arceus centric episode possibly tying in Silvally and Type: Null too

Unova:
>Hilda rides the ferris wheel with N
>a PWT episode
>old Plasma vs. new Plasma?

Kalos:
>a Korrina episode featuring Mega Evolution
>the player character discovers a hidden cave that features Mewtwo
>a Sina and Dexio episode where they decide to go on vacation, but they soon notice that their destination is full of Zygarde Cores. They also notice a strange wormhole in the sky

And they could top it off with Alola episodes.
>Gladion and Type: Null escaping Aether
>Hala and Tapu Koko fighting an Ultra Beast
>Lillie confronting Lusamine in Ultra Space

Thoughts? What do you think they could focus on next?
