The Arrow and the Flash are winding it up to their last few episodes and that includes the much awaited crossover between the two DC superheroes.

While both are caught in their own separate storylines as we speak, it remains that much of the brewing plots right now will eventually be tied up with that coming crossover and of course series finale.

A promo called the Superhero Fight Club, somehow gives viewers an idea of things to come.

We all know that the Arrow (Stephen Amell), the Flash (Grant Gustin) and Firestorm (Robbie Amell) have long been rumored for a team-up though it remains to be seen if the Atom (Brandon Routh) would be included in that mix.

Sad to say, if the promotional video is to be a basis, he may have a minor role but not one to do actual battle. The video shows all heroes and villains from both series in action, taking on one another. It even includes the much awaited confrontation between the Flash and the Reverse-Flash, Arrow vs. Ra's Al Ghul and the rest. Could this be the battles that await viewers in the coming crossover?

On their own, Barry Allen aka the Flash continues to try and dig deeper into the secret behind the Reverse-Flash and the fake Harrison Wells. And apparently he is getting a lot of help now with detectives West and Lance and of course Cisco.

As for the Arrow, Queen is pressed to make a decision on whether to accept Ra's Al Ghul's offer in light of the various developments that had transpired last time out.

Keep a close eye on the remaining episodes as both series near the windup in what has become an entirely successful series based from DC Comics.
