"Born in the nebula known as M78, together they fight for peace and justice throughout the galaxy. Warriors of great compassion and courage"

―Opening narration, Mega Monster Battle: Ultra Galaxy Legends The Movie

The Inter Galactic Defense Force (宇宙警備隊 Uchū Keibitai)[1][2] is a security organization originating from the Land of Light that seeks universal peace and justice. Out of the 18 billion Residents of the Land of Light, only 1 million are employed under the Inter Galactic Defense Force.


The founding of the Inter Galactic Defense Force

Thirty thousand years ago, the Land of Light was attacked by Alien Empera and his monster army in what would later be called the Ultimate Wars. The most decorated hero of this conflict was Father of Ultra, who dueled and defeated the dark emperor. Father of Ultra, then known as Ken, was made the first captain of the Inter Galactic Defense Force. Other Ultras soon joined the organization for the sake of promoting peace in the universe.

The new Inter Galactic Defense Force

Their numbers grew and eventually, the organization reached a million members strong. Ken was promoted to the position of Top Commander after the Ultimate Wars and took on the title Father of Ultra. Among the Space Rangers are the Ultra Brothers, many of whom have become a legendary presence on Earth.

Ultraman Mebius has stated that prior to the creation of the Inter Galactic Defense Force, Ultras of the Land of Light believed their powers should be used to do good. This implies they enforced justice across space in a less organized fashion.
