Justice League, Season Five

Superman:
[Fighting Darkseid] That man [Batman] won't quit so long as he can draw breath. None of my teammates will. Me? I've got a different problem. [Punches Darkseid through the wall] I feel like I live in a world made of cardboard. Always taking care not to break something, to break someone. Never allowing myself to lose control, even for a moment, or someone could die. [Punches Darkseid again] But you can take it, can't you, big man? What we have here is a rare opportunity for me to cut loose, and show you just how powerful I really am. [Punches Darkseid across the city with a single blow]
