Dragon Ball Z: Lord Slug, also known by its Japanese title , is a 1991 Japanese animated science fiction martial arts film and the fourth Dragon Ball Z feature movie. It was originally released in Japan on March 9 between episodes 81 and 82 at the Toei Anime Fair as part of a double feature with the first Magical Tarurūto-kun movie.

Gohan visits with Piccolo and shows him a new tune he has learned to whistle. Due to his advanced Namekian hearing, this causes Piccolo pain so he angrily orders Gohan to stop when they both sense an approaching threat incoming from outer space. Bulma and her father discover that a meteor harboring lifeforms is heading toward the Earth and will destroy the planet upon impact. Amidst mass panic, Goku and Krillin rush to intercept the meteor and hope to push it away by blasting it with Kamehameha waves but they are both rendered unconscious by the force of the meteor but it seemingly explodes in orbit. A spaceship then lands in one of Earth's cities.

An army of humanoid alien soldiers exit the ship and declare the Earth under the rule of their leader, Lord Slug. The soldiers attack a group of earthlings but Gohan arrives to defend them. Lord Slug observes that Gohan has a magical Dragon Ball sewn onto his hat which he loses during the scuffle. After his henchmen render Gohan unconscious and reveal the plan to convert the planet into a biological spaceship, Slug appears and uses telepathy to read Bulma's mind and learns about her radar used for tracking the Dragon Balls. Slug's men successfully gather the Dragon Balls and summon the eternal dragon Shenron who grants Slug his wish for eternal youth. Slug's forces begin transforming the Earth which begins to cause life to perish across the planet. Goku and Krillin are revived by Yajirobe who gives them each a healing Senzu bean. Gohan meanwhile resumes his assault against Slug's army and is rescued by Piccolo. Piccolo kills the henchman Wings and Gohan is overwhelmed by Medamatcha leading to Piccolo being injured when he jumps in front of an energy blast intended to kill Gohan. Goku and Krillin arrive and Goku easily kills Medamatcha and Angila. Slug appears and is attacked by Krillin who is quickly dispatched. Goku fights Slug but is overwhelmed and in a moment of rage, is seemingly able to access a portion of the Super Saiyan form.

Goku pummels Slug and during the battle it is revealed by King Kai that he is a Super Namekian, a bloodline of violent warriors obsessed with power who were banished from their home world. Slug assumes his giant form and begins to crush Goku between his massive hands. Piccolo intervenes to rescue Goku and before he is also crushed, tears off his own ears and calls out for Gohan to start whistling. The whistling deafens and weakens Slug, allowing Piccolo to transfer his remaining energy to Goku who powers up and manages to fly straight through Slug's abdomen and incapacitates him. Goku then ascends into the sky and begins preparing a Spirit Bomb in order to destroy the pods transforming the planet, but Slug manages to pursue him. Goku launches the Spirit Bomb at Slug which sends him hurtling into his own machines, killing him and saving the planet. Yajirobe heals everyone with Senzu beans as they celebrate their victory.
