In the original storyline as aired in Japan, Dairugger XV was simply an exploration robot, as well as an intended peace-keeping force. The Earth is in a time of prosperity. The president of the Terran League (the Galaxy Alliance in Voltron) launches a mission to explore beyond the galaxy. After commencing its mission of exploration, the starship Rugger-Guard is attacked by a ship of the Galbeston Empire. Dairugger, the super robot, is deployed in order to defend the Earth. It is somewhat by fate that they must help the people of Galbeston find a new planet before it explodes, and liberate it from its despotic Emperor. In the Japanese version, it does not have anything to do with King of the Beasts GoLion, as opposed to the U.S. version, Voltron: Defender of the Universe. There are three assault team units: Land, Air, and Sea. There are a total of 15 parts referred to as Rugger, which can combine together to form the super-robot Dairugger. The design of the 15 separate Rugger units came from the sport of rugby, since 15 players are required to form a rugby union. The U.S. version would rename the Galbeston Empire to Drule Empire, along with editing a fair amount of violence and sexual content to keep the show safe for general audience broadcast.

In the old days they'd go off into the country and hack each other up with swords, but these days, what with school, that isn't very practical. So some of them do something very un-Japanese. They strap on a big bike, roar around annoying people, and pound anyone they consider dishonorable. Now meet Eguchi Yousuke, leader of a high-school Biker gang AND the school's handicrafts club. Which means he divides his time between fistfights and fancy needlework. And if you think he's weird, wait until you meet the rest of his gang... (Source: AniDB)
