Battlestar Galactica alumnus Katee Sackhoff is joining the ever growing roster of supervillains on The Flash. Entertainment Weekly has confirmed that Sackhoff will join season four as the DC supervillian, Blacksmith.

Amunet Black, a/k/a Blacksmith made her debut appearance in Flash: Iron Heights #1 in 2001. The character runs a lucrative black market under both Central City and Keystone City, selling dangerous contraband to other criminals. Following her divorce from fellow supervillain Goldface, Blacksmith stole his special elixir, allowing her to fuse a metal suit on her body and control organic and inorganic matter.

Sackhoff will join the scarlet speedster on the fifth episode of the new season, entitled “Girls Night Out.” According to EW, this episode will also serve as the latest “mini-crossover” with Arrow. So far, Emily Bett Rickards (Felicity) is the only Arrowverse character confirmed to appear in the episode.

The Flash returns October 10 on The CW.
