Swinub is a fairly underrated Pokemon. He has 2 different evolutions and is one of the stronger ice types out there. No Pikmin can hope to be a match for this guy. I believe a Swinub could take down dozens if not hundreds of Pikmin with ease. One Avalanche attack and that’s basically game over. The Yellow Pikmin can try to think up a plan, but he won’t have the skills to put it into action. Swinub wins.
