The CW has been releasing a number of Superhero Fight Club posters as both The Flash and Arrow gear up for their season finales. Today, we get two more one-sheets from The Flash, featuring partners in crime Captain Cold (Wentworth Miller) and Heat Wave (Dominic Purcell) as they prepare to fight in a bloody cage match. This comes just before tonight's penultimate episode of The Flash titled Rogue Air.

In Rogue Air, Wells (Tom Cavanagh) once again gets the upper hand on the S.T.A.R. Labs team. Barry (Grant Gustin) realizes he needs to make a big move and reaches out to an old foe, Captain Cold, for help. Joe and Caitlin 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 and Firestorm! Written by Aaron Helbing and Todd Helbing and directed by Doug Aarniokoski, Rogue Air hits the small screen tonight. It will be followed tomorrow by the Arrow Season 3 finale My Name is Oliver Queen. While we await both epic episodes, take a look as Captain Cold and Heat Wave prove why their such badasses! Both characters will be seen in the spinoff DC's Legends of Tomorrow.
