Lord Slug is somewhat similar to King Piccolo, as both are Namekians who embrace darkness and are pure evil, but unlike King Piccolo, Lord Slug doesn't spare, he has no problem killing a subordinate for a simple remark about his old age. Another similarities to King Piccolo, Lord Slug wished for eternal youth. Lord Slug desired nothing less than to conquer the entire universe, though he does conquer planets in order to turn them into Battle Cruisers to travel the cosmos.
