Footnotes:

Takes place during Secret Wars II #1, as the Beyonder wears the form of the Molecule Man in this story.
This issue is also a part of the Scourge of the Underworld event.
Placed here as a best fit, since it is not clear where it would actually take place. Or what the point of it is.
These issues were not reprinted in the Secret Wars II Omnibus due to rights issues.
These two issues take place during Secret Wars II #8, as specified in that issue.
Deals with the fallout of New Mutants #37.
