Comics is just so weird in that way because it completely blurs the line. In some ways it's all fanfic, but in other ways, it's fanfic that becomes canon. I always notice that in comics fandom it's really common to hear people saying "my canon stops at..." or "in my canon..." and sort of mean it, because you can go in and out. And people will totally argue characterizations based on the things they've read and not others.

No one should have to be subjected to Greg Land just to read X-Men.
