Part of the main title screen for the film showcases what appear to be cave drawings of a giant Namekian, evidently Slug, as well as a creature with wings. It is unknown what race the smaller beings are, but they appear to be worshiping Slug.
There are two different and conflicting versions of Slug's origin. The original version states that Slug was sent off Namek as a baby to Planet Slug, much like the Nameless Namekian was sent to Earth, in order to save him from the cataclysms affecting his home planet. But he had a rare Namekian mutation from birth, one that made him pure evil; this made him a Super Namek.
The FUNimation dub states that Slug was born and lived on the original Namek sometime prior to the cataclysm. Slug, along with other Namekians, discovered the key to unlocking a higher consciousness within. They were known as Super Nameks, but they soon became intoxicated by their new power and began to misuse it, behaving much like the Saiyans. With the power of the Dragon Balls, the Namekians (most likely including 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 moving on. Lord Slug was probably the last surviving member of these Super Nameks.
In any event, Slug formed an army of demon-like soldiers as his conquest of space continued. He used his troops to conquer planets, freezing them to make them a home for his soldiers. He would sometimes alter a planet to turn them into a giant spaceship (known as a Planet Cruiser), and used them to move on to his next target.
Slug is seen approaching Earth. He kills Zeeun with a Finger Beam for remarking on his old age, and wants to have Earth converted into his new Planet Cruiser. As his soldiers start to fall to Gohan in an attempt to do this, Slug leaves his spaceship and takes the Four-Star Ball after noticing it on Gohan's hat. After reading Bulma's mind on how to obtain the other ones, he sends his Generals to bring him the remaining Earth Dragon Balls and then wishes for eternal youth. Lord Slug's scientist then starts Terra-freezing the planet. His forces are met with resistance from Gohan, Piccolo, Krillin & Goku; after his henchmen are killed, Slug confronts Goku. After swatting away Krillin, Slug proceeds to dominate Goku. But, Goku transforms into the Super Saiyan form for the first time and beats Slug down, breaking his arm.
Goku reverts to his normal form after Slug rips off his damaged arm. It regenerates, and after removing his helmet, he reveals himself to be a Namekian. Slug then transforms into a Great Namek, and once again dominates Goku. Piccolo, Gohan, and Krillin get back up and try to fight Slug. Piccolo rips off his ears and has Gohan whistle, causing Slug to double over in pain; the wavelength of Gohan's whistling makes it sound terrible to Namekians. Piccolo takes this opportunity to give Goku his energy. After regaining consciousness from Piccolo's energy, Goku then fights Slug again. Using Kaio-ken, Goku penetrates Slug with a punch, leaving a gaping hole through his chest and send him falling towards his ship, crushing both it and his remaining crew with his colossal frame. Goku then sets out to destroy the satellite that causes the terra-freezing. However, Slug is still alive and uses his dying strength to pursue Goku in an attempt to finish him off. Fortunately, Goku manages to reach out of the thick clouds and uses the sun's energy to create a Spirit Bomb which he uses to knock Slug straight towards his terra-freezing satellite, destroying it and Slug.
Plan to Eradicate the Saiyans
Lord Slug appeared again in the OVA Plan to Eradicate the Saiyans, as well as in Plan to Eradicate the Super Saiyans (the remake of Plan to Eradicate the Saiyans featured in Dragon Ball: Raging Blast 2), where he was revived as a Ghost Warrior alongside Turles, Frieza, and Cooler. Slug declares to Vegeta that he will pay for his past sins, and offers Piccolo a chance to leave the battlefield alive as they are only after the Saiyans. In the original version, Slug could not die unless he was killed the same way he was before, which resulted in Gohan whistling once again, which cripples Slug with pain and Piccolo finishes him off with a large energy blast. In the remake, he was impossible to kill unless the Destron Gas machine was destroyed.
- Lord Slug
Being a Super Namek, Lord Slug has immense power, especially in his prime. By the time he approached Earth, he has aged considerably, and his strength has waned from it. But by wishing for Shenron to restore his youth and making it eternal, he has returned to his prime and never again will it wane from old age, thus remaining in the time in which he has his immense power forever. However, Goku surpassed him as a "false" Super Saiyan. Unfortunately, the tables turned once Slug transformed into a Great Namek. In this form, Slug nearly killed Goku after the latter lost his transformation. King Kai guessed that Slug, in his Great Namek form, was more powerful than Frieza and Goku's "false" Super Saiyan form. Ultimately, it took a Spirit Bomb to kill him.
- Plan to Eradicate the Super Saiyans
In the Plan to Eradicate the Saiyans game Ghost Slug and Ghost Turles together are able to hold their own against the Z Fighters, but are ultimately defeated. In the OVA Ghost Slug is able to put up somewhat of a fight against Super Namek Piccolo.

Slug returned to the roster in Dragon Ball Z: Budokai Tenkaichi 3. In both games, Slug explains during his story mode he knows Goku is a Saiyan and had hoped he would be a good challenge for him. In Budokai Tenkaichi 3, King Kai claims Slug is from the endangered planet Namek and that he escaped Namek as a baby, confirming the Japanese dub account of Slug's origins.
