In an area with a sufficient amount of darkness, Fumikage summons Dark Shadow in his strengthened night form, its head vastly enlarged. In a single shot, Fumikage unleashes Dark Shadow so that it lunges at the target with tremendous destructive power capable of breaking through any obstacle in its way.
Fumikage first used this technique to assault one of the Paranormal Liberation Front's exits, taking out many of its lower-ranking members in one fell swoop, before clashing with one of its lieutenants and strongest members, Re-Destro. As the latter's Stress Quirk was unable to sufficiently support his prosthetic legs against the tremendous pressure Ragnarök put on them, he was overpowered and crashed against a wall.
- This Super Move shares its name with the term Ragnarök from Norse mythology, which describes a series of apocalyptic events that ultimately lead to the destruction of the world.
