The Pikmin OG
An OG started by SteveT and dutifully posted in by Masamune, Luigi of the Pipes, and recently Piku-Lord, the Pikmin OG is a story that takes place shortly after the Olimar leaves the Pikmin planet in the game 'Pikmin'. A small group of Pikmin, fearing that they'll become defenseless without the Olimar around, venture forth in search of a special nectar that will turn them into Alpha Pikmin.
The story began with fifty Pikmin (20 Red Pikmin, 15 Yellow Pikmin, and 15 Blue Pikmin), though only three in particular stuck out from the group: Wulfmin, Prophmin, and Arrmin. Over the course of the story they have recruited new characters and discovered new aspects of their world (mostly drawing from 'Pikmin 2', though with some originality).
The Pikmin OG tends to be more scientific than other OGs, though that is likely because 'Pikmin' is more scientific than most video games.
