Golgo 13 (TV)

Golgo 13 has been called a Japanese counterpart to James Bond, except with a darker character, a much more hardcore attitude towards sex, and a complete lack of morality. Golgo 13 is described as a mystery man of undetermined origin, possibility being at least part Japanese, who takes any assignment for any employer (it has been said he has worked for the CIA and the KGB) as long as the right price is given and will always fulfill his contracts, even if he has two or more opposing contracts at the same time. He is an uncanny sharpshooter, with near 100% accuracy and capable of lethal trick shooting, and regularly uses a customized, scoped M-16 rifle in his assassinations. He also is a heavy smoker of cigars. (Source: Wikipedia)

Dallos

At the end of the 21st century, Earth had to confront the problem of population increases combined with shortages in resources. Development of the Moon was seen as the way to solve the situation. The Moon's mineral resources reinvigorated the Earth and brought prosperity. However, the achievement of that vision proved painful for those who'd left their home world to settle on the Moon. One of Man's greatest dreams has become a nightmare for those who have been forced to live it out. Shun Nonomura doesn't realize it, but he's about to discover a weapon - one that can overthrow the oppressive Monopolice and bring freedom to the lunar colonists. The growing resistance movement is quick to adopt it, along with its creator, into their ranks as they rally around the mysterious alien monument known as Dallos... Dallos was made in 1983 by Studio Pierrot, becoming world's first OVA series. It was also the directorial debut of Mamoru Oshii, who would later go on to direct such films as Angel's Egg, the first two Urusei Yatsura movies, and Ghost in the Shell. (Source: AniDB)
