All the while he was receiving encouragement from Reiblood to destroy the Ultras once and for all. Bestowed with the Giga Battle Nizer and with his army of 100 monsters, he attacked the Land of Light for revenge. He eventually landed on a planet similar to the moon, where Reiblood appeared and baptised the Ultra Warrior into a Reionyx. The Space Garrison captured him, and he was exiled from the Land of Light for such an act was against the planet's highest safety regulations, meaning that Belial had threatened the safety of the entire planet for his pride. When he had the chance, he went to the Plasma Spark Tower, and was about to grab the Plasma Spark's core, but the light emanating from it was too strong for him to resist, he started screaming in agony and pain because of the light's power. Afterwards when Ken was elevated to the position of the Space Garrison's Supreme Commander and not him, Belial was consumed mentally by his hurt pride, and decided to siphon energy from the Plasma Spark to obtain more power. The two fought together in the Great Ultra War against Alien Empera, who impressed Belial with his power.
In ancient times, Ultraman Belial was a great Ultra Warrior, and a comrade of Ultraman Ken. However depending on various circumstances he changes into other forms, some unique to this version of the character. Normally, Belial resembles his canonical self.
