It starts with another instance of the Thing’s ongoing poker game.
Iron Man thinks Beast cheats, so he talks to him like an old dad. “Hank McCoy! You ruined this game on purpose!”
What interrupted the game is the dramatic portion of the issue. Annihilus, Blastaar, and Super-Adaptoid team up against Thing and The Avengers.
I think it’s the first appearance of Mrs. Blastaar.
Honestly, I could have loved an entire issue of the poker game.
Marvel did a great house ad for this issue.
