Lord Slug (Sometimes refer to as just Slug) is a Namekian and the antagonist of the fourth Dragon Ball Z Film, Dragon Ball Z: Lord Slug. it is explained that he is of the "Super Nameks" and like the others he was banished from Planet Namek sometime around 261 Age. Since then, he had gathered an army and became a conquer of planets, using terra-freeze and other methods to capture entire worlds. in Dragon Ball SF, he is the antagonist of the first film, Dragon Ball SF: The White Star Dragon Balls.

Early Life:
part of main title screen for the film showcases what appears to be cave drwaings of a giant namekian, evidently Lord Slug, as well as a creature with wings. it is unknown of what race the smaller beings are, but they appear to be worshipping Slug.

there are two different, conflicting versions of Slug's origin.

the first told in the japanese dub, states that Slug was sent off Planet Namek as baby, to Planet Slug, much like Kami was sent to Earth, in order to save him from the cataclysm affecting his home planet. but he had a rare Namekian Mutantion since his birth, one that made him pure evil. probably related to the mutation, he was also very powerful, a kind of Namekian called a Super Namek.

the second account told in the Funimation Dub, states that Slug was born and lived on the original Planet Namek sometime prior to the climate change that wiped out almost all Namekians. Slug, along with other Namekians, discovered the key to unlocking a higher consciousness within. they were known as Super Nameks, but soon became intoxicated by their new power and begin to misuse it, behaving much like the Saiyans. with the power of the Namekian Dragon Balls, the Namekians (most likely Guru) used Porunga to banish the Super Nameks from their planet for good. Super Nameks became nomads, moving from planet to planet, taking what they wanted and moved on. Lord Slug was probably the last surviving member of the these Super Nameks.

in any event, Slug formed an army of demon-like soliders in Planet Slug. he used his troops to conquer planets freezing them to make them a home for his soldiers. He later altered the planets to turn them into giant spaceships, and used them to move on to his next target. he went on conquering more and more planets for centuries.
