At the end of Arcade and both story modes the ending boss is one mother shut-your-mouth. To win, useing Baraca (or however you spell that thing's name) or Deathstroke, just keep cutting him. With that thunder god guy back up , run up to him, and press B, X, X, X, B, X, X, X. Then do it over. that will kill him. With Batman, keep throwing batarangs, smoke bombs, and smoke escapes. Throw him too. But the hints I just gave you will be useless if you can't get to him. So with Arcade use your best man or woman and when at the boss, switch to the person and win. Sorry, but I don't know any others. Good luck.
