When peace settled across the galaxy. the humans of planet Earth formed the Galaxy Alliance. Together with the good planets of the solar system, they maintained peace throughout the universe. Until the menace of Zarkon threatened the galaxy. A force of five young humans from Earth. Specially trained and sent by the Alliance to bring back Voltron. Indeed the space explorers came along and discovered the five sleeping lions. Each space explorer piloted one of the lion pieces. The leader of the group was Keith, who helmed the Black Lion and directed the formation of Voltron. Lance, the pilot of the Red Lion. The Blue Lion pilot was the Sven, although he was replaced Princess Allura from the planet Arus. Hunk, piloted the Yellow Lion, while the Green Lion pilot, Pidge, was a human from the planet Balto.

Voltron: Legendary Defender Continuity

Human beings are primarily inhabitants of the planet Earth, a small, life-bearing world in the Milky Way Galaxy, with the nearest star system being Alpha-Centauri.

Human beings have in recent times made great strides in space exploration, though with the exceptions of a handful, have had no contact with extraterrestrial lifeforms. What contact has occurred has been entirely due to events caused by the Galra Empire, Voltron, and the Altean Royal family.

Humans have been known to had contact with extraterrestrial life prior to the awakening of the Blue Lion in the desert by the soon-to-be Paladins. This is because Keith, the current Red Paladin and Second-In-Command of Team Voltron, is known to possess both human and Galran heritage, having been descended from a member of the Galra-centered resistance organization known as The Blade of Marmora. And Shiro, the current Black Paladin and Leader of the Defenders of the Universe, Matt and Samuel Holt were captured by the Galra Empire when they study of ice samples for signs of extraterrestrial life on Kerberos.
