Ness
Ness is the game's quiet leading character and most events in the game focus on him. At the game's beginning, a talking bee from the future informs Ness that he and three others will be responsible for repelling an evil alien that has been carried to Earth on a meteorite. In battle, Ness fights with baseball bats and psychic powers.
Paula
Paula joins the party after Ness rescues her from the deranged "Happy Happy Cult." Paula's psychic abilities outstrip those of every other character. Paula equips a variety of frying pans for battle and her "Pray" ability generates random effects that could either help or hinder the party.
Jeff
Jeff is the son of eccentric inventor Dr. Andonuts. He joins the party after receiving a psychic distress call from Paula and sneaking out of his boarding school. Jeff's hereditary genius allows him to fashion bits of garbage like a broken harmonica into devices helpful in combat. In battle, Jeff attacks with bottle rockets and his recycled tools, but he lacks any psychic ability.
Poo
Poo, the Prince of Dalaam, is the final character to join the party. He teleports himself to the aid of the other characters in the foreboding swamp called the "Deep Darkness." Poo's Dalaamese training makes him a formidable psychic combatant and his "Mirror" technique allows him to take the form of an enemy for the rest of the battle.
