"Fire Buster II" is a weapon that Eudial uses in Sailor Moon S.
Anime[]
After the original Fire Buster was destroyed by Sailor Venus, Eudial created a more powerful version. Like its predecessor, it was able to blast fire which was strong enough to overpower Moon Spiral Heart Attack. It was also able to blast glue and she trapped the Sailor Senshi with it.
When the Holy Grail appeared she used the weapon to cover the room in flames to help her reach it first. Chibiusa used Luna P Extinguish to put them out but she just reignited the area. When Sailor Moon gained her Super form, the flames were extinguished and she was able to stop the weapon and send Eudial out a window by raising her hand.
