SUPERBOY: "I don't physically age, at all. I'm not immortal; I'm aging internally."

[From "Young Justice" episode 202, "Earthlings." Originally aired May 5, 2012.]

Greg Weisman says:

"Superman's the strongest of the Leaguers. Icon, Captain Marvel and Wonder Woman are up there. Aquaman and a telekinetically enhanced Martian Manhunter and a Quantum-energized Captain Atom are close. I'd put Red Tornado, Hawkman and Hawkwoman just behind them. Neither Flash nor Plastic Man nor Zatanna nor Atom have super-strength, but their powers can sometimes give them more oomph. At the "bottom" are folks like Batman, Green Arrow, Black Canary, Black Lightning, Rocket, though of course, they're all way stronger because of their training than the average human being. And of course, you have the Green Lanterns, who can use willpower and rings to mimic strength too - and maybe even top Superman when they're on their game. Same - in his own way - with Doctor Fate. I think that covers the whole League."
