3 rivals with main one being a snob/tsundere girl. Also a nerdy boy and the counterpart of the protagonist.

There is gonna be a lot of sidequests, one of the biggest being a treasure hunting subplot. Kinda similar thing like the koroks of breath of the wild.

Professor looks very much like an anime old man.

First gym leader is a female scientist and uses bug type.
Gyms now have more than one area, gotta get through them to reach the leader. First one was a forest maze.

Early new pokemon:

Dark Red and black striped bug pokemon with burning wings when attacking.

Small Bunny with oversized gloves on fists and one ear hanging over his right eye.

a yellow/black striped hoopoe with high up static hair.

Legendaries are a leviathan and a fairy horse.

Water starter stays pure water.
Looks like an admiral in last evolution with a weapon in his right hand, pretty much what many would expect.

Grass starter goes fairy at last stage. Looks like big tiger with fangs and blooming flowers on its body. Has a special attack that’s tied to the flowers.

Fire starter goes ghost at final stage and looks like dinosaur. Long flamey hair going down his back.

That’s all for now, will return when i had some more visits.
