Aquaman's first guest appearance in his post-Convergence garb kicks off in Gotham Harbor, with the Sea King beating the snot out whatever passes for Superman these days:
Suddenly a massive ship flies back, grabs The Sun with some mechanical tentacles, shaking the formerly World's Finest Team off it. Turns out the whole thing was a plot from a group called The Dark Commands to grab the thing in the first place:
As Aquaman and Ukur shake hands, Batman and Superman squabble, ending with the Dark Knight Detective warning Superman to "Stay out of Gotham." Some things never change.
Not having read this series before, I had not a clue what was going on, nor am I up to date with Superman and Batman's new look(s). So I did my best to follow along, enjoying the site of Aquaman head butting the Man of Steel and surviving. He's still a giant hothead, so when he lectures Ukur about listening, I feel like the next panel really should have been Ukur giving his king a Liz Lemon-size eye roll.
