Almost exactly one month ago, The CW unleashed a Superhero Fight Club trailer that featured stars from both Arrow and The Flash fighting in a massive steel cage. Ever since then, the network has been releasing individual posters with each character that was featured in this unique crossover video, and today we get one more, featuring The Flash star Robbie Amell as Ronnie Raymond, a.k.a. Firestorm. We also see the other half of Firestorm, Dr. Martin Stein (Victor Garber), looking on as Ronnie showcases his fiery abilities.

This poster comes just one day before the second-to-last episode of The Flash, "Rogue Air", debuts on Tuesday, May 12 at 8 PM ET on The CW. The episode centers on Wells (Tom Cavanagh) once again getting the upper hand on the S.T.A.R. Labs team, as Barry (Grant Gustin) realizes he needs to make a big move and reaches out to an old foe, Captain Cold (guest star Wentworth Miller), for help. Joe (Jesse L. Martin) and Caitlin (Danielle Panabaker) warn Barry that Cold can't be trusted. True to form, Cold has his own agenda that involves the meta-humans trapped in the containment cells. As things seem to be going from bad to worse, The Flash gets reinforcements - Arrow (guest star Stephen Amell) and Firestorm (guest star Robbie Amell).

The previous trailers for "Rogue Air" show both Arrow and Firestorm standing side-by-side, marking the first time real-life cousins Stephen Amell and Robbie Amell will share the screen together. We'll have to wait until next season to see if Robbie Amell and Stephen Amell will get to share the screen once again. Check out Firestorm's Superhero Fight Club poster below.
