Demore Barnes will appear on the show as Henry Hewitt, a character better known to Firestorm fans as Tokamak. Hewitt is described 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.”
“The Flash” returns to the CW on Tuesday, October 6.
