Scovillen

Scovillen is a fictional element appearing in DC Comics, most notably associated with the superhero character Firestorm. Its properties are largely conceptual and have been defined and redefined over the years to serve the narrative needs of the stories it appears in. Generally, Scovillen is depicted as a highly unstable and radioactive substance, often synthesized by Ronnie Raymond and Martin Stein, the two halves of Firestorm.

When exposed to external energy sources or combined with certain other elements, Scovillen is capable of generating immense power. This power can manifest in various forms, including concussive blasts, heat generation, and even manipulation of the fundamental forces of the universe. The inherent instability of Scovillen is also a key characteristic, often leading to dangerous uncontrolled reactions or the need for constant containment. In some interpretations, Scovillen is responsible for the unique abilities and the distinctive costume of Firestorm. Its exact atomic structure or origin beyond its creation within the Firestorm matrix is rarely, if ever, detailed, serving primarily as a plot device.
