Lord Slug

Slug (スラッグ, Suraggu), known as Lord Slug (スラッグ様, Suraggu-sama) to himself and his underlings, is a Namekian, and the titular main antagonist of Dragon Ball Z: Lord Slug. It is explained that he is one of the Super Namekians and was sent to Planet Slug as a baby to escape the extinction that was about to ravage Namek. As he matured, the evil in his heart began to overwhelm his character thanks to a rare mutation unique to Namekians; this transformed him into a Super Namekian. Since then, he had gathered an army and became a conqueror of planets (in Funimation dub, he was banished from Planet Namek sometime around Age 261 along with other Super Namekians).
