If the JLA movie was to have a big team fight scene.

Flash or Green Lantern or MMH (though I doubt we see J'onnz anytime soon)

The funny one--like Iron Man and Rocket Racoon--likely Flash since Ezra Miller was cast.

GL.

He is the one you can have the most fun with. He's the JL's Hulk, especially if they go with Hal "the tool" Jordan.

I think GL has some of the most potential for good imagery, but Flash is up there too

Superman, Flash, or Lantern.

Flash. A cinematic Infinite Mass Punch or some other outrageous feat that he usually does would instantly make him the favorite.

Visually Green Lantern would rock it if they did something good with him. If they make his constructs cool enough he could easily be the most fun to watch.

Personally though I really hope to see some awesome fight scenes from everyone. The Avengers are great and all, but not that interesting to watch fight. Include Superman just wrecking shop with his powers, make Batman pull some real ninja moves (unlike The Dark Knight films where he fought kinda slow and more like a street brawler than a ninja), put some Wonder Woman sword fighting in there, Green Lantern with the complex (and awesome) constructs, Flash doing something like the Quicksilver scene in DoFP, Aquaman destroying the enemy with his trident, Cyborg using all kinds of crazy gadgets... then my friend, you have something amazing on your hands.

Im going to go with GL. Hal or John.

I pray that The Flash pulls a DOFP Quicksilver and steals the spotlight to shut all the nay sayers up about Ezra Miller.

Batman, Flash, Martian Manhunter

In terms of power Flash maybe. In terms of badassery and actual 'stealing the show' Batman obviously.

Wasn't there a rumor that GL is going to arrive at the end of the movie to warn the leaguers about Brainiac?

Depends on how the scene was directed, choreographed and yadda-yadda.

Superman or batman, these are the main twins of WB. They also wanna see them shine

I think if any of DC's superheroes could launch into stardom from the DCCU, in a similar fashion to Iron Man from the MCCU, then it would be the Flash.

If they get his likable character, humour and powers right it could be a real launch pad for him. Thing is though, I'm not sure there's many better ways of showing a speedster's powers than the Quicksilver scene in DoFP (maybe there are loads I just can't think of any), But the whole "time has stopped and he can do whatever he wants" thing has been done now, it won't be original anymore.

@thebhramabull: I wouldn't mind a speedster fight like they had in Flashpoint.

Green Lantern most likely, due to the variety of things he can do. Also Martian Manhunter if he makes it in.

@the_stegman: Your big speedster vs speedster moment was in the latest Flash episode.

Flash or Green Lantern would steal the show in Justice League and here is why:

Flash: They will try to make something so incredible that everyone forgets Quicksilver's awesome scene from X-men DOFP.

Green Lantern: They will try to show everyone that he isn't lame like his movie was(Which I liked to some extent)

Batman. Here he will take the combined roles of Cap, Natasha, and Clint in Avengers.

If they do him right, Lantern. the range of his constructs and what he could do with them could be one of the best things in the film.

Either Hal or Barry

I think Wonder Woman

Obviously Batman

I could see them all stealing the show for various reasons. Out of all of them though I think the Flash or Martian Manhunter (if used) would steal it. Maybe Aquaman. Maybe.

I hope Green Lantern steals the show.

Most likely Batman but I hope it's Flash.

Bats or Flash

Shouldnt be difficult to make Cyborg look damn cool as a technopath, with some serious firepower, and a potentially awesome design. Ya know, since we wont be seeing Jonn for a while.

It could literally be any of them.

But my money's on Flash, Batman or Superman.

But then again Zack snyder could make WW look really cool just look faora.

If they really use the full potential of Wonder Woman's lasso instead of her just using a sword the whole time then I think she could have some of the most visually dynamic fighting.
