NOTE: EARTHBOUND THE MOVIE IS NOT COMING OUT RIGHT NOW, EVEN THOUGH THERE IS A HIGH PERCENT CHANCE IT WILL, I AM STILL WORKING ON EARTHBOUND 0.
Pokey Minch, also known as Porky Minch (ポーキー・ミンチPōkī Minchi), is a character in EarthBound and Mother 3, but also appears non-canonically in Super Smash Bros. Brawl. A portly and obnoxious next-door neighbor, he is Ness's neighbour in the suburbs of Onett and the older brother of Picky Minch. Pokey's family seems to hold a grudge against Ness's, because his father, Aloysius Minch, allegedly loaned a few hundred thousand dollars to Ness's father (though Aloysius admits it could have been a lot less), and was never repaid. Although he and his father found work in Fourside as consultants for the city's mayor, the Minches continued to feud with Ness's family.
Pokey's battle music in EarthBound is untitled, but it is known as "Cease to Exist" in Japan and "Pokey Means Business" elsewhere. His themes in Mother 3 are "Master Porky's Theme" and "Absolutely Safe Capsule", and are played during the initial confrontations with him and following his retreat into the Absolutely Safe Capsule, respectively.
