This JLU (Justice League Unlimited, the animated series) lineup is the most powerful, and the most interesting in my opinion. Having two women and at least one man who isn't Caucasian (even though there are three alien's on the team) helps to bring something different to the table than the typical scenarios.
I am really loving how The Flash is being drawn now so I took advantage of that and ran with his effect! I look forward to redoing this lineup to be up to date with the new 52. Stay tuned!
