Megazone 23 (series)

Megazone 23 is a Japanese original video animation (OVA) movie series that takes place after humanity has abandoned an uninhabitable Earth on massive colony ships called megazones, with this series following the events of Megazone 23. The original series is broken into three parts: Parts I, II, and III with each of them focusing on a different story in the same universe.
