Porky

Porky, oftenly entitled Lord, (Pig) King or Master, originally localized as Pokey, is a character from the MOTHER series, known as Earthbound in America. He is the major antagonist in EarthBound/MOTHER 2, and is the main villain in MOTHER 3. Porky appears as a boss in Super Smash Bros. Brawl in his Spider-bed Mech. In the Subspace Emissary, he fights Ness and Lucas and later appears in The Great Maze. His theme for Brawl was first revealed in the Smash Bros. DOJO!!. Several depictions of Porky as a kid appear in the background of the New Pork City, along with his statue. A variation of His Highness' Theme is among the playable tracks in New Pork City.

Though Nintendo of America localised his name as "Pokey" in EarthBound, they used "Porky" in his subsequent appearences in the Super Smash Bros. series. His original name, ポーキー (Pōkī), can be interpreted as either, but with MOTHER 3's "pig" themes, fans believe Porky to be the intended name.

Role in Subspace Emissary
When Lucas walks alone in The Ruined Zoo, a giant statue of Porky Minch appears and begins chasing him through the zoo, attempting to crush him. At the end of the scene, Lucas gets his leg stuck under a root and is about to be hit by the Statue, when Ness appears to Lucas's rescue, destroying the statue by using PK Thunder and PK Flash. It reveals Porky inside his spider-like bed machine, and the boys battle him. Ness and Lucas defeat Porky and destroy the machine. His appearance in Super Smash Bros. Brawl is outside the Mother series' canon.

Trivia

 * Of all the bosses in Super Smash Bros. Brawl, Porky is the only one who interacts with characters who are from his own series only; only interacting with Ness and Lucas.
