Though Goku gave up being a cop to become a detective, his sense of loyalty never faded. Thus, when someone starts killing his former colleagues, he has to get involved. The job might be more than he can handle, however, as he's up against not only a half woman/half motorcycle cyborg, but also the creator of the strange eyes that have been driving his friends to destruction! Death seems likely, but the tables may turn once a mysterious benefactor implants a computer in his left eye -- a computer that can obtain any information, control any device, even destroy the world!
Cobra is a futuristic ladies' man with a gun for an arm and selective memories of his past. His inherited weapon, the Psychogun, is an unusual tool which responds to his very thoughts. Due to his strength and choice of weaponry, Cobra lives his life as a pirate whose main goal is to elude the nefarious bunch of evildoers known only as the Guild. Follow his space adventures as he lives on the run from both sides of the law!
I may be recommending these because they are both by Buichi Terasawa. But this guy know how to write a story and definitely knows how to illustrate. both anime are very reminiscent of each other.
The style and feel of both series are very similar and it is the surrounding characers, and mostly the women, that are so alike as to be interchangable between the two anime.
Also, if cool guys with cybernetic enhancements that makes them unique is your thing then Goku: Midnight Eye and Space Adventue Cobra should be just what you're looking for.
Both are based off manga's by Buichi Terasawa and have very similar vibes and storytelling. Goku himself is very much like Cobra and they both posses in a way, a "power" or ability that gives them an edge when it comes to fighting. Great action, adult themes (Goku gets away with more being an OVA), very cool sci-fi settings, familiar imagery, etc.
In a dystopic and futuristic Tokyo, humanity’s genetic code has gone awry. At the forefront of the technology is Fraud, an organization conducting experiments on people such as Kei and Ai – two escaped “headmeters” with hefty psychokinetic powers. The sinister Mr. Lee wants nothing more to retrieve Ai back to his clutches, as she seemingly holds the key to immense power; Kei wants simply to keep Ai safe; and the evil Lai Lo Ching has his own master plan. Along with the help of the amnesiac headmeter K2 and a trusty sidekick, Kei must fight to protect Ai from the evils of Mr. Lee, Lai Lo Ching, and the state of the world itself!
Something about Ai City to me felt like it was another creation straight from Buichi Terasawa, heavily known for his Space Adventure Cobra series and Goku Midnight Eye. The dark city visuals, action, cyborg villains, and cyberpunk aesthetics of Ai City reminded me of Midnight Eye the most. If you want some good classic short sci-fi fun these are awesome.
