A new teaser from Marvel Comics portends a potential re-write of Marvel history - starting with the origin of the Fantastic Four.
The teaser asks "Who really gave the Fantastic Four their powers?" calling into question their classic origin of being bombarded by cosmic rays during an experimental space flight - and implies there's some kind of entity or person behind their true origin.
It's unclear whether other aspects of Marvel history could be rewritten as a part of this story, or if it's the next FF tale.
Either way, as the teaser foretells, Marvel history will be "destroyed" in March 2019.
