Dragon Ball Z: Lord Slug

Gohan and Piccolo are enjoying a quiet moment when they feel an immense presence closing in on Earth. News soon spreads that a small planet is on a direct collision course, and Goku and Kuririn try to divert it with a Kamehameha—only to be blasted back when the attempt fails. Just before impact, the mysterious body veers away on its own and detonates, revealing itself as a massive vessel carrying what looks like a fortress.

From the structure pours an army that proclaims Earth the property of Slug, the self-styled “king of the universe.” As the defenders fight to protect the city, Gohan loses his Dragon Ball, giving Slug the opening he needs. After extracting information from Bulma and taking her Dragon Radar, Slug orders the Dragon Balls gathered, uses them to restore his youth, and—reborn younger and far more formidable—sets his sights on conquering the planet.
