In Ultraman Trigger: Darkest Belial from the Start

Rog transmigrated and became Ultraman Belial. Trapped in a dimensional rift and suffering unbearable agony, he was fortunate to awaken the Super Villain System. He obtained the Absolute Darkness form from the start, becoming the first darkness in the universe. Then, armed with immense power, he entered the world of Ultraman Trigger. Yuna Shizuma: “Why are you possessing me?” Yurien: “Such powerful darkness! Even stronger than the darkness of the ancient giants!” Carmeara: “I pledge myself to Lord Belial!” Ultraman Trigger: “Geed! Come save me, your dad's escaped!”
