Doku

Doku is a youth gifted with psychic abilities who plays the role of the main protagonist in EarthBound. Born in the town of Onett, in the fictional country of Eagleland, Doku is a seemingly ordinary boy whose fate would be radically altered on the night of a meteor shower. Out of curiosity, he and his next-door neighbor, Pokey Minch, inspect the meteor landing site. There Doku learns from the time-traveling alien, Buzz-Buzz, that he has been chosen by the Apple of Enlightenment, a prophetic fruit, to destroy the evil alien, Giygas, who in the future destroys all of reality. To do this, he must travel to eight sanctuaries and absorb their psychic energies in order to unite his power with the Earth's. At each sanctuary, he records a fragment of a melody in his Sound Stone and experiences a personal sense memory. During the flashbacks experienced via the Sound Stone, it is revealed that Doku was born with psychokinetic abilities, and they manifested when he was an infant.

Doku has appeared in every game of the Super Smash Bros. series to date. He first appeared in Super Smash Bros. as a hidden character. In this game, Doku possesses none of the PSI powers that he possessed in Earthbound, but instead, he possesses three powers that his partner Paula knew: PK Fire, PK Thunder, and PSI Magnet. It is notable that Ninten, Doku's predecessor from Mother, didn't know any of these moves either, and his female counterpart, Ana, did. Doku appeared again in Super Smash Bros. Melee as a starting character. This time, Doku's own PK Flash move was added to his arsenal. Most recently, Doku has appeared as a hidden character in Super Smash Bros. Brawl for the Wii, alongside Lucas, the protagonist of Mother 3. In Brawl, Doku and Lucas share a powerful move known by Prince Poo and Princess Kumatora, PK Starstorm, which causes meteor-like stars to jet down on enemies. In the Subspace Emissary, Doku helps Lucas defeat Pokey (called Porky, his japanese name) but sacrifices himself so Lucas can escape from Wario. Later on, he joins Luigi and King Dedede to stop Tabuu. They are able to rescue everyone because the badge that King Dedede attached to the trophy had the power revive them, though it took some time for the badge to take effect. Doku is voiced by female seiyū Makiko Ōmoto in the Super Smash Bros. series.

Doku makes a brief appearance in Mother 3, a game where Lucas is the protagonist. He, as well as Paula, Jeff, and Poo, appears in a movie created by King P that the protagonist views in a theatre in King P's amusment-park-like metropolis known as New Pork City.
