Mr. Molecule is an enemy in EarthBound, found in Magicant. They resemble molecules with two beady eyes. They are capable of using PSI Fire α, PSI Freeze α, PSI Thunder α, and PSI Flash α. They can be fought in a group of three, a group of four, or a group of two with a Care Free Bomb. Like Fobbys and Pitbull Slugs, Mr. Molecules are not able to concentrate at the beginning of the battle. While they have extreme weaknesses to PSI Fire, PSI Freeze, Paralysis, and Brainshock, Ness is the only member of the party to visit Magicant, meaning that only their 99% weakness to Paralysis can be used against them. However, they have a 0% chance of being affected by Hypnosis.
