Porky Minch appears in the adventure mode of Super Smash Bros. Brawl, The Subspace Emissary, as a boss. Here, he is seen as a high-ranked member of the Subspace Army who attacks Lucas in The Ruined Zoo using his Pig King Statue and a fleet of Primids. Before the Statue can kill Lucas, Porky's ex-best friend Ness appears and destroys the Statue with PK Flash. From the exploding Statue emerges Porky in his Mother 3 spider mech, but he is quickly defeated by Ness and Lucas in a boss battle.
Porky Minch also appears as a sticker. Attaching this sticker to the bottom of Ness or Lucas's trophies in The Subspace Emissary increases their PK attack by 15.
In this appearance he is referred to "Porky", a more proper translation of his name, even on the label for his sticker, which uses his EarthBound clay model for the image. It was most likely changed for this game because of his pig-themed empire in Mother 3, as well as all the signs saying "PORKY" in New Pork City.
