I made some of my own if they aren't too small. The goal was to have something similar to Kanto and Unova where they work as a standalone region with all the classic shitmons.
The starters are Grass/Water, Fire/Grass, and Water/Fire
The regional mammal is an incredibly angry fucker that evolves into a dopey capybara
The fossil pokemon are based off of early humans and ancient deep sea hallucinowhateverthefucks.
The bug thing sitting on a planet is a fucking dung beetle. Its ball gets bigger as it levels, then at level 80 it sends the ball into space to become a planet and chooses to stay with you.
The regional caterpillar has a heinously long time between evolutions but evolves into a really fucking strong dragon type. Not sure on its design though.
