Dark Fire is a fire-based attack performed by Koan in the anime and RPG. In the anime, the attack was first used in episode 60 in which she blasted of blue fire at her enemy. The attack was powerful enough to defeat Sailor Mars' fire soul attack but was put out but Rei's new Burning Mandala attack.
In Sailor Moon: Another Story, the attack could be performed by either Koan or Nergal in which it could burn the Sailor Guardians.
- In the DiC English dub, the attack is called Ice Fire due to the attacks' blue color
