It is unknown how the past Aku's destruction affected his existence.
He's stout, wears sunglasses, a brown suit with a sheriff badge, has leather colored skin, has pointed teeth, and, of course, a pig snout.
He talks loudly in a gibberish pattern with a New Orleans accent. He is implied to be sadistic and corrupt.
The pig sheriff has a shotgun that earlier on the bridge shot out handcuffs, but later shot pellets. Sheriff Piggy also rides a brown multi-turret tank.
