Dragon Ball Z: Lord Slug is the fourth Dragon Ball Z movie produced. It was originally released in Japan on March 19, 1991, between episodes 81 and 82, and later released in America by FUNimation Entertainment in 2001. It is the first Dragon Ball Z movie (not counting the later Ultimate Uncut edition of the previous three movies), but the third feature (the Bardock - The Father of Goku and History of Trunks specials were dubbed a year before), to be dubbed with FUNimation's English in house voice cast.
An asteroid alert is wreaking havoc all over the planet as it is going to destroy the entire Earth. Goku and Krillin go to deflect the asteroid off course so it does not hit Earth. They have been told they cannot destroy it because it is inhabited, and at the time they do not know who inhabits it. They attempt to move it using a combined Kamehameha, but apparently miss and are blown away by the fierce winds produced by the near-clash of the asteroid with Earth.
The asteroid passes near Earth but misses the crash, exploding soon afterward. However, a spaceship from the asteroid lands on Earth, full of soldiers who serve Lord Slug. Along with his crew of vicious fighters, he has traveled from planet to planet wreaking chaos, and Earth is his new target. The way they dominate a planet is to literally change its atmosphere, Terra-freezing the planet. By conforming it to their liking, they make it more suitable for themselves and almost unbearable for any other people, including the native occupants of the planet. Later they transform the planet into a giant spaceship, and move on to find a new planet to conquer.
Upon their landing, a nearby Gohan attempts to stop Slug's soldiers. Slug notices the Dragon Ball Gohan has on his hat. After reading Bulma's mind, Slug learns about the Dragon Balls and how to get them. Lord Slug has by now aged hundreds of years and is rapidly approaching the end of his life, so he sends his minions to gather the Dragon Balls, and uses them to restore his youth and health; like King Piccolo before him, being fully restored gave him a far greater power.
Goku, along with his son Gohan and Piccolo, arrive and square off against Slug's team and manage to defeat them all. The final battle against Slug is left in the hands of Goku. Goku is able to take Slug on in an incredibly fierce battle. Slug gains the upper hand with his Power of Darkness technique and pummels Goku around. As Goku is on the verge of giving up, Slug's taunts combined with the sight of such pointless slaughter pushes Goku over the edge and he transforms into a False Super Saiyan. With his new power, Goku easily dominates Slug and destroys one of his arms. Now, Slug reveals his Namekian nature by regrowing his arm and removing his helmet, and transforms into a giant version of himself. King Kai reveals that Slug was one of the rare Super Nameks, who began to misuse their power to the point that the Namekians used Porunga to banish them from Namek forever. In his new form, Slug turns the tables on Goku again.
Piccolo intervenes and attempts to fight Slug but is easily beaten. In a surprising move, Piccolo tears off his ears and tells Gohan to whistle. Exploiting a weakness of all Namekians, their extremely sensitive hearing, Gohan's whistling is able to bring Slug to his knees.
Piccolo gives what little strength he has left to Goku in his battle against Slug. Thanks to Piccolo, Goku is able to use the Kaio-ken, and manages to punch a hole through Slug's stomach, weakening the Super Namek severely. Goku flies up above the clouds to deliver the final blow to Slug with a Spirit Bomb powered-up from energy taken from the sun. The Spirit Bomb heads straight into the freezing generator, taking Slug with it and destroying him.
Following Slug's defeat and the end of the threat, the friends reunite and are given Senzu Beans by Yajirobe. The final scene involves Master Roshi waking up from his nap which he started before the aliens landed, and he wishes that something interesting would happen.
