Favorite: The Flash. Gotta Love him, cause of his sense of humor. Even during the worst situations he's able to crack a one liner. And c'mon he's the fastest man alive. Batman is 2nd because...he's batman! Shayera is in 3rd for being an awesome fighter!
Shayera: "Who's hand is that?"
The Flash: "Sorry!"
I don't really have a least favorite member because they are all great. Don't know why everybody is hating on wonderwoman though....Somebody's jealous...hehe just kidding
