Ultraman: The Eternal Core Stripped Tregear from Me from the Start

Thirty million years ago, the Eternal Core tore Dark Trigger from his physical body, sending his consciousness and power adrift across the universe. When he awoke, he possessed a mechanical weapon belonging to the Melosa, a Darklops, and began a new journey to grow stronger in the Ultraman universe. Seeking greater power, he seized the power of a Reionics and unexpectedly obtained the Dark Ring after reaching the summit of O-50's warriors. Now transformed into a new Dark Warrior, he continues to seize power and subdue monsters throughout the universe, all so he can return to his own universe, absorb the Eternal Core, and reclaim his body.
