one day at the Watchtower, the Justice League has met to talk about possible recruits for the Justice League

Martian Manhunter: We should consider if this is for the best. No one wants to have another Injustice League.

Superman: We understand. But all of us can't be in one place at the same time. So for League membership, I nominate Icon.

Green Arrow: Why? Cause you think he might be Kryptonian, like you did with Shazam?

Shazam: You thought I was Kryptonian? Cool.
