The screenshot accompanying this article about Justice League Heroes amuses me. Ignoring everything about the game itself, the choice of leaguers is always tricky.
By tradition you always have seven members. Slots 1-3 have to go to Superman, Batman, and Wonder Woman. For four and five you pick the best second-tier heroes in the DC arsenal, Flash and Green Lantern. Flash’s speed makes him able to do almost anything, unless you slow him down in purpose, and GL’s power ring can by definition do almost anything. So that leaves you with two slots. One always goes to Martian Manhunter, because he’s been in every version of the League and because his powers are just ill-defined enough that you can use him as the easy-out for any story you’re not sure how to end.
And that leaves the seventh slot. DC just doesn’t have anyone on the same tier as the rest of them. Hawkman’s a great choice, but Hawkman’s really out of place with the rest of the cast. He belongs in the Green Arrow, Black Canary, and The Atom’s league, which also rules out all those characters. Aquaman has the name recognition, and unlike most I think he’s a great character, but only when you keep him in his element, the sea. Aquaman in the sea is great, but what’s the rest of the League doing there? Grant Morrison threw in Plasticman, but he’s not on the same tier as the rest, either. The game apparently likes Zatanna, but she’s solidly a tier 3 character, though she has the advantage of being another woman to round out your diversity to 2 women, 1 alien, and a black guy, assuming you’re using John Stewart as your Green Lantern.
