Urusei Yatsura

Earth faces a huge crisis. Aliens want to invade the planet. Humanity's only hope rests with Ataru Moroboshi, who was chosen to represent Earth in a one-on-one duel with the aliens' chosen warrior. There is only one problem with this plan. Ataru is a womanizing, stupid loser. How in the world can he hope to succeed? Selected to fight for the aliens' right to take over Earth is Lum, their curvaceous, bikini-clad princess. Luckily for Ataru, the duel takes the form of a game of tag. All he has to do to win is grab Lum's horns.
