Nelson Mandela Muntz, Jr. is Nelson Muntz's son from the future. He appears to have a strong resemblance to his father and a different hair design. When Hugh Parkfield says the wedding is cancelled, Nelson does his laugh, while his son does it, too . His mother is either Sherri or Terri . In "Future-Drama", Nelson Junior looks like a combination of Sherri, Terri, and Nelson.
