Potassium is a big lug with the appearance of a sasquatch and has a mysterious past. He starts off as a member of the antagonistic group known as the Synvasion Force, but due to his clumsiness and obliviousness, he isn’t reliable enough to handle the big missions like his comrades. His strength, however, completely makes up for it. Potassium can easily lift objects 10 times his weight, including other elements and can chuck them away with just as much ease. Hydrogen would have to rely on wits and speed if he ever wanted to stand a chance against this brute. On a side note, despite his obliviousness, Potassium has an extensive knowledge on all types of food and tends to fantasize about it when he’s hungry.

Potassium is an enemy in Atomic Protocol, but doesn’t become playable until the second arc, Atomic Vengeance, where he finally sees the error of his ways and decides–no, I should say BEGS to become a member of the MPA as well. Since he is the largest and heaviest character, he is undoubtedly the slowest. However, his amazing strength can make up for it. Not only can he punch enemies into submission, he can pick them up and use them to clear away groups of baddies with one swing, suplex, or a mighty piledriver. Those of you who’ve played Wario World will get the idea. He can even break open new pathways that other elements can’t get through, just as long as there are cracks in the walls or floors, or if the foundation is weak and shaky. Because Potassium is an alkaline element, staying in water for too long without any protective armor will eventually cause him to disintegrate! Even if he did have armor, he’d sink right down to the bottom. That can be advantageous, however, when trying to open new paths underwater.
