Universe 6 and 7 are a pair remember? They both closely resemble one another(same planets/species but with different histories. Example: Planet Sadala was never blown up in Universe 6, and Planet Earth had originally destroyed itself via warfare until the Super Dragon Balls were used to restore it). Piccolo isn't on the Universe 6 team lol... It's just another Namekian xD
