Leijiverse

The Leijiverse is a term used to described the shared but loose Star System of works by Leiji Matsumoto. This does not encompass all of his works however, usually only his most notable including Space Pirate Captain Harlock and Galaxy Express 999.

Summary
Most series take place in space with the use of special starships of different design including but not limited modified battleships like the Yamato and Arcadia as well as special steam trains for voyages like the 999. A myriad of alien species also exist in the far reaches of space, although some were wiped out by elements like the Mazon of the Machine Empire. Planet Earth has itself become a hallmark with its role in the multiple series it appears in, often as a point of interest for domination or as something to avoid because of the government officials in their corrupt state. More often than not, major character come in and out of series sometimes as guest characters, or other times through doubles. The most notable of which include: Captain Harlock, Maetel, Tochiro, Emeraldas, as well as several other characters related to the previous lot including but not limited to the cat Me-kun and Bird.

Other series take place during more recent times including the American frontier period or around wars. These series are at best implied to be related to their more famous counterparts including Gun Frontier.
