The Badoon take over Arkon’s dimension, someone escapes to get help, and the Badoon capture the Fantastic Four (who tried to protect the escapee).
The X-Men go save the FF, with Arkon. Ororo and Susan lead negotiations, and it is implied that the Badoon get inappropriate when they search the women for weapons.
It’s a nice team-up.
It’s the first time the Fantastic Four meet a Shi’Ar.
And there’s the obligatory “everyone laughing” ending, which was originally a part of every Stan Lee story. In this one, Kitty gets (yet another) new outfit.
She’s worse than Janet Van Dyne.
It’s an annual, so it’s a simple, big-fight tale. Perfectly fine for what it is, but nothing great. Except that tag line: Ou, La, La, Badoon! My younger readers probably won’t get the reference, but it is the catch phrase from a ubiquitous TV commercial for an old brand of jeans.
