T-Rex: One day Batman was fighting a crime when Green Lantern showed up. "My whole deal is that I am in the space police," Green Lantern said, "and there's a new space law that says you can't punch people like that."
T-Rex: Batman was like, "Whaaaaat?"
T-Rex: Green Lantern explained that the Lantern Corps protect space, and he's been assigned to this region of space, and Earth is in space, and according to Space Law you're not allowed to punch people without due process, so Green Lantern was gonna have to take him in. Batman said something to the effect of "uh lol I'd like to see you try lol" but cooler, because he's Batman. And then they fought!
Utahraptor: And Green Lantern used his ring to make giant boxing gloves?
T-Rex: You know it!
T-Rex: Luckily Batman knew how he always did that, so he used the strategy of "just avoid the giant boxing gloves". It was super effective, and Green Lantern lost. At first everyone was like "yay, screw the space police" but when the Space Riots came they really missed their services, so it was complicated.
T-Rex: There were a lot of issues around the interplanetary legitimization of force and everyone on Earth finally got to have a frank discussion about them, all because of Batman.
T-Rex: *sigh*
T-Rex: He really was SO GREAT
