originally I was saying supes, but then, yeah, J’ohn is basically the only one.
I voted for J’onn mostly to make sure he always has a place to be. Everyone else consistently gets solo comics, but J’onn sometimes gets left out if he’s not in the JL. Plus, I think he’s good for the job. He listens well and connects the team.
JJ is the one best capable of quickly organizing the group and doesn’t have the same full-time jobs of Supes/Bats/WW
I know he’s young, but you can’t deny he’s connected–to EVERYTHING! So my vote for permanent chair of the Justice League would go to CYBORG.
