Lord Slug

Plot

An army of humanoid alien soldiers exits the ship and declares the Earth under the rule of their leader, Lord Slug. The soldiers attack a group of civilians, 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; he 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 eternal youth. Meanwhile, life on Earth begins to perish.
