The past form of Ultraman Trigger. As a Giant of Darkness, he hunted for the Eternity Core with Carmeara, Darrgon, and Hudram. Theform and dark power that Trigger abandoned were revived thanks to Carmeara’s dark spell.

Immediately after the revived Trigger Dark was dispersed, there was a man who took in the darkness wafting through the air with telekinesis. Ignis, the Lishurian alien, carried the absorbed darkness in the Blank Key and created a Dark Trigger Key, using it with the Black Sparklence to transform into Trigger Dark.
