Ultraman Cosmos vs. Ultraman Justice: The Final Battle
Respected as the judge of the universe, Delacion is an existence dedicated to Universal Peace through the concept of Universal Justice. For this reason, it aligned with Ultraman Justice in trying to fight chaos in the universe.
Later, she predicted that humans would become the next great threat to interstellar peace. Sending the Glokers, they rampaged across Japan, making sure not to let a single human leave Earth with Justice destroying Cosmos for interfering. However, the red Ultra later had a change of heart and rebelled against Delacion. As he was assisted by a revived Cosmos, Justice destroyed all of Delacion's forces stationed on Earth. When Giga Endra appeared and tried to destroy the Earth's life, Cosmos and Justice fused into Ultraman Legend and successfully destroy the doomsday weapon. Delacion appeared again, and trusting the Ultras, they changed their view towards humanity while leaving them unharmed.
Ultra Galaxy Fight: The Absolute Conspiracy
Though unseen, Delacion dispatched Cosmos and Justice on a mission to assist Ultraman Neos, Ultraseven 21 and Ultraman 80 in fighting Leugocyte and Gymaira. As Cosmos and Justice touched down and spoke with 80, they informed him that Delacion had requested they follow an unusual energy reading from their universe, eventually ending up at the location of Leugocyte.
