Ataru Moroboshi

(諸星あたる, )

A student at Tomobiki High School, Class 2-4, Ataru suffers from an incredible amount of bad luck, having been born on Friday the Thirteenth, during a major earthquake, and Butsumetsu, the unluckiest day of the Buddhist calendar. Thanks to this lack of good fortune, his triumph in the game of tag that saved Earth from Oni invasion turned into a defeat for him. His victory statement, intended to confirm his then-girlfriend Shinobu's promise to marry him if he won, was misinterpreted by Lum to be a marriage proposal. Much to his chagrin, she accepted.

Ataru is very lecherous. His main goal in life is to live in the center of a harem composed of exotic and beautiful women, including Lum and most of her alien friends. His pick-up techniques would creep out most stalkers. Usually, he just walks up to a woman he's never met before and asks for her name, phone number, and address. If Lum, who views him as her husband, should witness these ultimately futile efforts, she regularly zaps him with massive quantities of electricity, but they do nothing to slow him down.

Once he decides to go after a particular female, virtually no force on Earth, or any other place in the galaxy can stop him. This tenacity can work to his advantage in dire times, as it makes him determined to succeed regardless of the odds. Ataru may come across as stupid and lazy, but he is actually quite intelligent, able to manipulate situations to his advantage. Though he often tries to escape from Lum and openly flirts with other women, he really does have feelings for her. He refuses to admit it, but deep down, he proved in the later episodes that it was Lum that he truly loved. Voiced by Toshio Furukawa (original Japanese) and Michael Sinterniklaas (Those Obnoxious Aliens dub), Steve Rassin, and Vinnie Penna (English Movies).

In the French dub of the Urusei Yatsura anime, Ataru's name is Ronnie.
