The Prism

The Prism

Dayton Optical Systems designed The Prism, a device with the ability to create synthetic red sun rays. In November 2017, Dark Arrow, Overgirl, and Eobard Thawne broke into the company and stole The Prism.[1] Later though after the trio's plan was foiled, The Prism was presumably retrieved and returned to Dayton Optical Systems by the heroes.
