An OVA miniseries (6 episodes) that follows a futuristic bounty hunter named Iria whom gets embroiled in a conspiracy involving a suspicious mega corporation & a nearly indestructible hostile alien lifeform called "Zeiram", after being sent out on a mission to rescue the crew of a ship that has sent out a distress signal.
It clearly owes it's core concept to "Alien", however it does enough of it's own to justify it's existence. The conflict between Iria & Zeiram becomes personal in a way that it's inspiration wasn't, and Zeiram itself has an eye catching design (a theme that carries over to the series as a whole, it mixes sci-fi grandeur with traditional Japanese/Asian aesthetic influences much like other sci-fi anime of the time like "Tenchi Muyo!" & "Outlaw Star"). Not the best thing ever, but I liked it more than I had imaged I would going in.
