Actually please tell me if anyone else remembers this

I remember seeing it mentioned in Wizard Magazine. Even then, I thought it sounded dire.

Mark Millar and Grant Morrison made for a weird team

You are not alone in remembering this. A Grant Morrison-written thing, if memory serves. Wasn't to my taste, but the concept was/is a hoot.

Absolutely. Skrull Kill Krew by Grant Morrison and Mark Millar. I have the issues in my office en.m.wikipedia.org/wiki/Skrull_...

I saw the comic in the quarter bins

One of Grant Morrison's few non-X-Men contributions to the Marvel Universe.

No no somebody else mentioned the eating Skrull cow meat thing to me too

“Skrullovoria Induced Skrullophobia” and those who fought against it were called the Skrull Kill Krew
