Demore Barnes The Flash

Central City’s S.T.A.R. Labs might want to beef up their security.

The Unit alum Demore Barnes has been cast in The Flash‘s second season as Henry Hewitt, familiar to Firestorm comic fans as the villain Tokamak.

According to ComicBook.com, which first reported the news, Henry is a charming but cocky scientist who was affected by the same particle accelerator explosion that created The Flash. When Caitlin Snow recruits him to join the S.T.A.R. Labs team, Henry begins to fulfill his destiny as a powerful meta-human.

The Flash returns Tuesday, Oct. 6, at 8/7c.
