A helmet or face-mask constructed of Ruby-Quartz and used to contain the power of Cyclops' optic blasts.
History
One of the earliest versions was made by the Hellfire Club and secured to Scott's head with a locked strap below his ears.[1]
The Hellfire Club learned of Cyclops' inability to penetrate Ruby-Quartz when Warhawk infiltrated Xavier's School for Gifted Youngsters on a fact-finding mission. Emma Frost's technicians at Frost International developed an adhesive Ruby-Quartz gel that was deployed by a Hellfire Knight based on the data stolen by Warhawk.
The Ruby-Quartz helmet was redesigned and put on the imprisoned Scott Summers after the Avengers vs. X-Men conflict and the death of Charles Xavier.[2] It was later destroyed when Cyclops broke out of prison.[3]
