I’m covering this annual because something pretty important happens: Black Bolt and Medusa get married!
And it’s a Marvel wedding so, of course, there’s a violent wedding crash. A skrull and Kree warrior show up and fight through the proceedings. The Watcher makes an appearance, too, and he hasn’t been seen in a continuity comic (i.e., one that isn’t a What If?) in years.
John Byrne did the plot.
