At the end of Pikmin 3, the Pikmin are left alone and I thought, what happens next?
The idea I came up with is, that the onion merged all different kinds of Pikmin together to create a superior Pikmin. One might call it the Pikmin Emperor. It has vast amounts of strength, a stonelike skin and is atleast three times bigger than the average Pikmin.
A Pikmin ready to lead all Pikminkind to a new age of prosperity!
