As a successor to the Reionics, Reibatos tries to fulfill both Alien Rayblood and Ultraman Belial's failed legacy by reviving an army of monsters and conquer the universe.

Through his words, Zoffy deduced that he is trying to pursue the Giga Battle Nizer in the Monster Graveyard and leaves with Jack while Orb received a special training in Zero's subspace dimension, Shining Field (シャイニングフィールド, Shainingu Fīrudo).

Zero transported Orb to Reibatos' realm and the Ultra quickly unleashed an all-out attack to prevent his regeneration before he finally delivers the finishing blow.

In the Land of Light, Orb received congratulation for his assistance in the mission and was offered the Star Marks and a place in the Space Garrison for his bravery but politely refused due to his nature as a wanderer.

[a] Ultra Fight Orb was teased during the initial announcement of Ultraman Zero: The Chronicle, appearing at the very corner of the biography series' advertising poster.
