The imitating alien Impossible Man guest stars in a story called “Anything You Can Do…”
I know a lot of people hate Impossible Man because he’s ridiculously powerful but is never portrayed that way in comics–and probably also hate Warlock for the same reason. They can change shape into ANYTHING. It’s ridiculous. But it’s fun to see them fight each other.
This whole annual is just a big danger room fight.
And there’s sports. And swimming.
There’s no story here, it’s just silly fun. Lots of fun.
