Pokemon buffs, rejoice! A slew of never-before-seen Pokemon have just been announced for "Pokemon Sun and Moon," and interestingly, these also tie into the game's day and night course.

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.

Evolutions For Rockruff

Next off, we have the evolutions for Rockruff. Interestingly, Rockruff evolves into a couple of peculiar versions based on what time of the day the evolution takes place. Despite a striking difference in their Midday and Midnight forms, both evolved versions of Rockruff are called Lycanroc.
