From SmashWiki, the Super Smash Bros. wiki

Poo (プー, Pū) is a fictional character from EarthBound, he is the prince in the far away land of Dalaam, adored by every female he meets. After vigorous Mu Training, he is deemed fit to help Ness and travels to Summers to meet him. He is the only character in EarthBound to learn PK Starstorm and he can also use PK Freeze, PK Thunder, PK Shield, PK Teleport, PK Brainshock, PK Lifeup and PK Healing. However he doesn't learn the Omega versions of any of these (sans Starstorm) and PSI wise is considered the weakest in the party, however he makes up for it with physical attacks, which are incredibly stronger with The Sword Of Kings. He is also the only member of the party able to mimic an enemy to get to their weaknesses.
