Here's a sneak peek at what you can expect from the upcoming role-playing video games in the Pokemon series.

Passimian

First off, the fighting type Passimian, which is exclusive to "Pokemon Sun," but players can still acquire this unique monster in the Moon version of the game by trading it with a friend. As far as it origin is concerned, Passimian seems to be based on lemur, such as sifaka or the ruffed lemur, according to reports on BulbaPedia.

Oranguru

Following that is a normal psychic Pokemon dubbed, Oranguru. Though this monster originally hails from "Pokemon Moon," those who have the Sun release, can trade with their friends. No prizes for guessing, Oranguru is based on an orangutan.
