|This article is about a/an planet in Uchuu Keiji Sharivan.|
Iga is a planet that had been defeated 2,000 years in the past by the Space Crime Syndicate Madou, forcing it's inhabitants to flee throughout the universe for it's survival. After Madou is defeated by Iga descendant Den Iga, the planet began to become repopulated with those descendants as they returned to their homeworld.
The original Space Sheriff of Iga was Den Iga, the original Space Sheriff Sharivan who became stationed on the world after defeating the Madou. Thirty years after the planet was reclaimed, other Space Sheriffs such as Kai Hyuga (the second Sharivan) and Seigi (Space Sheriff Estevan) would also emerge from this world.
