She was able to attack with her hair and also had the ability to reverse the flow of time, causing any attacks by the Sailor Senshi to be returned to them. Using her Mercury Goggle, Sailor Mercury determined that after Ryuax used her powers, there was a distortion in time in which the Senshi could attack her. Chibiusa volunteered to bait Ryaux and she was saved from Ryuax's counter-attack by Tuxedo Mask. The Senshi then defeated her with Sailor Planet Attack.
Ryaux's vocal attack was called "Ryuax Power."
