We were aware of the 616 claim, but a bit apprehensive to run with it because of how determined the series seems to be to not reference anything from Godzilla's past appearances, as well as how generally wacky it is and incongruous from the timeline (from what I've heard, anyway; not a Marvelhead). If nothing outright contradictory happens in Infinity Roar and/or no further clarification comes out, though, we will probably end up calling it canon.
Regarding Godzilla vs. Marvel, the admin I consulted (ABB) checked Destroys the Universe #3 and not only didn't find any references to the one-shots but something that contradicts them: Cyclops and Professor X are unsure if the latter can psychically sooth Godzilla, even though he did so in Godzilla vs. X-Men. I don't know why the Marvel wiki thinks they're 616—maybe just because their plots aren't as obviously insane as the rest of that series—but I don't buy it. I've not heard any confirmation of their placement, and it would also just be peculiar for a series to be 33% canon. I don't think we have sufficient information to claim it.
Btw, I went through with merging the accounts. Your edits and such on the Mikezilla account should now be attributed to this account.
