There’s also at least two Cthulhu mythos ones! These are parodies, not official tracts!

I think there was also a fantastic four one…

The actor that played cyclops was Lois Lane’s husband in the supes flick. Not sure if he left the X-Men series for that though.

The date after the series title indicates when the series started, not the publication date of the actual panel. It’s there to clarify that it’s in the 300th issue of the original run, not the current one, or any of the ones that came between.
