- Origin: Space
At some point in the past, Ilt created Gigadelos, who was meant to protect lifeforms throughout space. As other races saw Gigadelos' capabilities, they wanted one for themselves as well, so Ilt created more Gigadelos for them. When the Gigadelos went berserk due to Ultraman Tregear giving it emotions, Ilt set out to track one of them down to Earth.
He kidnapped Hiroyuki Kudo and stole his Ultra Taiga Accessories, leaving him unable to transform while binding him to a pole. Ilt did so because he was afraid of leaving so much power in the hands of a single individual after seeing what happened to Giadelos, who had reappeared. However, Hiroyuki told him that they are not just some items, but rather his dear friends. Homare Soya tried to rescue Hiroyuki, but Ilt teleported the both of them away before Homare was able to do anything.
Ilt tried to shut down Gigadelos using his Delos Visor, but Kirisaki suddenly appeared and stole the Accessories back from Ilt, only to return them to Hiroyuki. As Taiga fought against Gigadelos and used the Night Fang Ring, Ilt saw through Kirisaki's intention of allowing Hiroyuki to transform. After a while, Ilt decided to shut down Gigadelos and have Taiga destroy it.
Hiroyuki met up with Ilt one more time after the battle. He asked what he would do from now on, and Ilt said that he would travel through the universe to shut down the other remaining Gigadelos. He told Hiroyuki to believe in his friends. Homare came to get Hiroyuki, who wanted to introduce Ilt to him, but as he turned around he saw that Ilt had already disappeared.
