Justice League Unlimited, Season 2

Superman:
This is the hardest thing I've ever had to say... I'm guilty. We're guilty. Of the sin of hubris. We had the best of intentions, to be Earth's guardians, to keep you safe, but we failed you. We looked down on the world from our tower in the sky, and let our power and responsibility separate us from the very people we were supposed to protect. No one should ever be afraid of us. For that reason, we're decommissioning the Watchtower. The energy weapon up there is already gone; we're taking down the station as well.

[The crowd looks astonished and whispers amongst themselves]

Superman:
There's more. We want to thank the members of the Justice League for your courageous service, but in the future, you'll all have to act as independent agents. We're not going to be an army anymore. As of right now, we're disbanding the Justice League. This is the end.

[The founding members begin to walk off the stage, but are stopped when Green Arrow speaks]

Green Arrow:
Says who? You remember what we did yesterday? We saved the world, again. You don't think that has any value? Well, think again, pal! The Justice League goes on, with or without you. Look, nobody can question your service or commitment to making things better. If you're quitting because you think you've already done your fair share, fine. We'll throw you a parade. But if you're quitting because it's easier than continuing the fight, then you're not the heroes we all thought you were. The world needs the Justice League, and the Justice League needs you, Superman!

[The crowd cheers and claps, along with Superman's fellow Leaguers. Green Arrow shrugs, and Batman gives Superman a subtle smile. Superman smiles back, and returns to the microphone]

Superman:
All right! Okay! But there are going to have to be some changes. Maybe we can open an embassy on Earth, so we can be closer to the people. We can have a rotating staff...

Batman:
[to Wonder Woman, as Superman continues] You guys can handle this. I've got work back in Gotham. You've got my number.

Wonder Woman:
I think so.

Batman:
[to Green Arrow] Quis custodiet ipsos custodes?

Green Arrow:
"Who guards the guardians?" We got it covered. [rides off with Black Canary]
