Lord Slug

Lord Slug is a Super Namekian who was exiled from his home planet due to the evil nature within him. Having wished for eternal youth, he led a crew of alien pirates across the galaxy, conquering planets and converting them into mobile war bases. He confronted Goku during the third Dragon Ball Z movie and demonstrated power that initially overwhelmed the young Saiyan — only to be defeated when Piccolo telepathically gave Goku a hint allowing him to awaken the Kaio-ken. Slug is notable as a rare Namekian villain.
