One, the book being released this month should not be called Fantastic Four #500.
OK. I'll go along with that. However, it is the 500th issue of Fantastic Four.
Two, Thor #500 is not the 500th issue of Thor
So far, so good.

WRONG. No Marvel comic has reached 500.
But, we'll just have to agree to disagree on this point.
