The Ruby Ray of Rouleau is a weapon used by Vilgax.
It consists of red gemstone lodged in a bracelet mounted on the back of Vilgax's right hand.
The Ruby Ray of Rouleau could be used as a laser projector, and was able to considerably weaken Ultimos with one shot. According to Vilgax, Ultimos' ability to survive the shot was unusual, suggesting that most other beings would be either immediately killed or left unconscious and defeated.
