EXCLUSIVE: The Flash Casts Demore Barnes as Firestorm Villain Tokamak

Demore Barnes has been cast as Henry Hewitt, better known as the Firestorm villain Tokamak, on The Flash, ComicBook.com has confirmed exclusively.

The CW describes the character as "a charming, but cocky scientist who was affected by the same Particle Accelerator explosion that created the Flash. When Caitlin Snow (Danielle Panabaker) recruits him to join the team at S.T.A.R. Labs, Hewitt jumps at the opportunity to fulfill his destiny as a powerful meta-human."

In the comics, Hewitt was the head of a corrupt energy conglomerate who tried to play hardball with Congress to manipulate markets on his behalf.

Tokamak's most notable accomplishment was probably the creation of Firehawk, a superheroine with powers similar to Firestorm's who was created when Hewitt kidnapped a Senator's daughter and subjected her to an experiment designed to recreate the accident that birthed Firestorm. He later attempted the process on himself, which is what gave him powers.


The character has made only sporadic appearances, most recently during the Dwayne McDuffie run on Firestorm in 2007. The New 52 villain Dataxen has been compared to Tokamak, but their only real commonality is having energy-based powers and operating in armor.
