Dragon Ball Z: Lord Slug

Gohan Son and Piccolo are enjoying a quiet moment when they detect a massive force heading toward Earth. News spreads that this force is actually a small planet on a collision path with their world. Gokuu Son and Kuririn try to deflect it with a Kamehameha, but the attack fails, and the two are thrown back by the blast. Just as the object nearly hits Earth, it suddenly veers off course and explodes. The small planet turns out to be a vessel carrying what looks like a castle. A vast army pours out, announcing that the planet now belongs to Slug, the self-proclaimed king of the universe. While fighting off the invaders in the city, Gohan loses his Dragon Ball, which Slug seizes. After probing Bulma’s mind and stealing her Dragon Radar, Slug orders his forces to gather the wish-granting orbs. Once he has them, he uses their power to restore his youth. Now young, cunning, and immensely strong, Slug sets his sights on ruling the world.
