If Marvel sticks to its standard Comic-Con playbook, the trailer will probably serve up the basic premise without revealing the major plot twists. Fans are hoping the preview will include the first full look at Robert Downey Jr’s Doctor Doom. It will possibly also depict the first meetings of the Avengers, Fantastic Four, and other MCU heroes. Fans might also get a tease for long-rumoured Avengers/X-Men showdowns. Infact, we can be prepared for a hint of the multiverse-scale conflict powering the story.
