On Twitter, DC Nation asked the question of who you would pick first, not your full JL team.
My first pick would be Black Canary. She has great leadership skills and her mastery of martial arts would come in handy. The downside is that she might not always be the most sociable person in the DC universe.
I could go by favorite or I could go by most powerful, but really, it’s not the League without the Martian Manhunter. Anybody else is a nice-to-have at best.
Martian Manhunter is the pick, but if he wasn’t available to pick I’d go with Nightwing just to show that this ain’t your father’s Justice League.
Ralph Dibny The Elongated Man (with Sue by his side of course!)
Naturally I would immediately retcon out the attack on Sue by Dr. Light! I mean, if they can retcon it in it can be just as easily retconned out…(actually I’d write out a lot of the tragedy in DC. There’s enough tragedy in real life and not every Super Hero has to have a Batman-style origin)
Martian Manhunter. Other characters with comparable powers are usually too busy with their own problems. Besides, J’onn helped to found the JLA, served on it during the Detroit years, and saw it become an international team. That’s dedication.
Nightwing. He’s grown a lot and has developed his leadership skills really well over time. He also would be a good encourager. I would just love to see it.
