X Men Apocalypse NowXL Men, about a team of larger superheroes
The inevitable sequel: 2XL (OK, the movie was X2, but X2L doesn't quite work)
XL Men: The Last Stand wherein their eating gets out of control and they risk never getting up out of bed again (crisis averted by the end of the movie so as not to kill the franchise)
XL Men: First Class yo, these biggies don't fit in economy, and sure don't eat economy!
XL Men: Meals of Future Past in which the team has to go back in time to change some of those first steps that eventually led to total domination by diets foods
(sadly I've not come up with anything for X Men: Apocalypse )
