Great Ultra War

&nbsp The Great Ultra War was a conflict that pitted the army of Alien Emperor against the Ultras over the Land of Light. Although Emperor temporarily managed to takeover the planet, the Ultras fought back and defeated him.

During War Events
Although the events are unclear, it is known that Emperor took control of the Land of Light after leading the most successful attack on the Ultras, something that various Ultramen foes had trouble doing. However, his reign was short-lived as the beings of light fought back, initiating the battle between light and darkness.

At the end of the war, Alien Emperor and Father of the Ultra engaged in their infamous duel that decided the fate of the Land of Light. The results came to a draw and both powerful fighters earned mirroring scars on their hips as a reminder of their brutal battle. Emperor, weakened by Father of the Ultra's Ultimate Sword, fled into hiding for generations.

Aftermath
After the war, Ultraman King had Father of the Ultra establish the Space Garrisons to protect and watch the Land of Light as well as the rest of the universe in case a crisis like this ever happens again.

The War had an impact on various species. Alien Temperor wanted to follow Emperor's example to conquer the Land of Light, which ultimately failed.

Years later, Emperor would make his full return to Earth where he would cause most of the events in Ultraman Mebius (series). However, he was defeated and ultimately destroyed by Ultraman Mebius Phoenix Brave Mode, making Mebius the first and only Ultra to ever accomplish such a feat.

Emperor would attempt revival again but was thwarted by the Ultraman Mebius and the Ultra Brothers.
