All characters are in their prime. Batman gets exactly one month of prep time for all four of them and can bring any gadget/tool he can fit in his fanny pa- err I mean utility belt... Vader gets just what you'd expect him to have. Chief is armed with a BR, two Halo 3 magnums (hue) two frags, one plasma and one energy sword. Supes is well, Supes. and Dora has her Backpack, backpack. Backpack, backpack... Who wins? Personally, I think Dora would solo.
