Yesterday, The CW posted an intriguing new videothat featured the heroes and villains of bothArrowandThe Flashsquaring off in a “superhero fight club.” The network has debuted three posters, featuring Arrow (Stephen Amell), Arsenal (Colton Haynes) and The Flash (Grant Gustin) inside the massive steel cage from yesterday’s video. It isn’t expected that this “superhero fight club” will be featured on any show, but it’s possible that this unique arena could be used in theArrow / Flash Spinoffthat will feature characters from both hit programs.

The Flashreturns after a brief two-week hiatus with"All-Star Team Up", which featuresArrow’s Felicity Smoak (guest star Emily Bett Rickards) arriving from Starling City along with her boyfriend, Ray Palmer (guest starBrandon Routh), who flies in as the Atom. They’ve come to visit S.T.A.R. Labs as Ray needs help with his suit. Their timing turns out to be fortuitous because it’s all hands on deck after a meta human named Brie Larvin (guest starEmily Kinney) unleashes hundreds of robotic bees to attack and kill her former co-workers, including Dr. Tina McGee (guest starAmanda Pays). A group dinner with Barry, Felicity, Ray, Iris (Candice Patton) and Eddie (Rick Cosnett) turns into a disaster.

Arrowis also returning from a two-week hiatus tomorrow night at 8 PM ET with"Broken Arrow", where Lance (Paul Blackthorne) continues his mission to take down the Arrow so Felicity orders Oliver to keep a low profile. However, when a meta-human named Jake Simmons (guest starDoug Jones), who kills people with blasts of energy and plasma, starts terrorizing Starling City, Oliver is forced to ask Ray for help, as the unlikely duo is forced to team up to save the city. Take a look at these new posters below to
