For the uninitiated: Cobra is the space-age, blonde-mulleted badass depicted in the DVD cover below. And that thing where his left hand should be is the Psycho-Gun, the Excalibur to his Arthur. He's been the basis for two Japanese TV series, a couple OVAs* and a full-length feature. This DVD release looks like a pretty packaging of the character's original (1982-83) exploits. GGMLK wants.
*Original Video Animation (OVA) is a distinctly Japanese home-video film format.
