Cobra

Cobra's signature weapon is his Psycho-gun, a cybernetic arm-laser which is connected to his brain and capable of targeting enemies without needing a line-of-sight. This allows him to defeat most foes with ease, but some are not so vulnerable to the laser itself; the gun also drains Cobra's mental energies after extended use. For backup he carries an old-fashioned Magnum revolver. Buichi Terasawa created the main character based on the famous French actor Jean-Paul Belmondo. Cobra's facial features bear resemblance to Belmondo's, and the peculiar sense of humour Cobra exhibits throughout the story seems to have been inspired by the characters Belmondo played in films.
