A while ago I read part of a comic storyline on Imgur and can't remember which issue this was. It seemed to me something out of a more recent Justice League comic but a) I'm not that familiar with DC and b) maybe I am wrong about the art style but it reminded me with late 90's X-Men art.
What I remember is as follows: Batman is standing at the gate of Arkham Asylum (on the inside of the compound) while Superman, Wonder Woman and Flash are on the other side of the gate. For some reason they want to enter Arkham but Batman won't let them. Superman then tries to shatter the chain with a heat ray but the chain pulverizes into Kryptonite and Batman is kinda smug and says to Flash and Wonder Woman that Superman isn't the only one for which he has this kind of plan.
