I think that the rooster is great, but there is too many characters involved in Batman. If there is one character I would take out, then it would be Solomon Grundy.

Where are the Villians? Just Joker, Harley and Grundy is weak.

I think I read somewhere that some pic showed the number of slots for characters which came out at 24. Maybe 12 heroes and 12 villains? Personally, I would get rid of Catwoman and Harley. Batman has much much better foes than this and personally I would like to see Poison Ivy with some plant based attacks (say a giant venus flytrap eating up Ivy's foe) and maybe Freeze or Killer Croc to add variety and other powers to the mix.

Who is Nightwing fighting in his screenshot?

I want MK10 or an action game based on MK, like a remake of mythologies. :D
