Ultraman Orb Chronicle
Ultraman Orb THE ORIGIN SAGA
A mysterious ring of light was located at the unexplored mountain peak called Warrior's Peak (戦士の頂 Senshi no Itadaki). When Gai and Juggler tried to harness its power, the former was chosen and in turn was transformed into Ultraman Orb in his first form, Origin The First.
After Queen Bezelb was defeated, Gai returned to this planet and his Origin the First form was upgraded to Orb Origin, before flying off to his second mission.
Chapter 3: 'The Man Who Stole The Black Hole' Arc
After Shorty died from defusing the Balloonga Bomb and Juggler and Biranki captured, Gai returned to this planet and received the Orb Ring. Gai also receives his third mission to stop the revival of the Ultimate Lord Monster in Planet Earth.
A long time ago, Grigio and her brothers managed to climb up the Warrior's Peak and were rewarded with Gyros and the R/B Crystals. They were then sent to defeat Reugosite, the destroyer. However, they lost the battle and crashed down towards Earth as a meteor, in what became known as Ayaka City while Reugosite drifted away in space.
Ultra Galaxy Fight: New Generation Heroes
Orb visited to Planet O-50 to relieve himself of stress. Before he could, a wormhole opened, and out came Ultraman X Darkness and Ultraman Geed Darkness. The dark copies attacked Orb, who retaliated after sensing darkness from the two. Despite getting the upper hand in his Lightning Attacker and Thunder Breaster forms, he was eventually overwhelmed by the fakes, who started to drain his energy. Fortunately, Ultraman Victory arrived to save Orb. After a brief scuffle, Victory used his EX Red King Knuckle to as a smoke bomb so he and Orb could escape. While the two Ultras made it to the Land of Light, Geed Darkness and X Darkness already succeeded in their mission, meeting up with their creator and using the light energy to create a dark version of Orb.
- The name "O-50" is derived from the 50th Anniversary of the Ultraman Series during Ultraman Orb's run.
