Not the original, of course, as they were all in the X-Men films. The spin-offs should be the revamped X-Factor government team that were commissioned by the government as their own salaried mutant team. Led by government agent Valerie Cooper, the X-Factor team went on various missions on their behalf. Pretty much Marvel’s mutant Suicide Squad.
The show could operate in a 24, or Blindspot fashion, where the mutants are sent on missions by Cooper providing security for the country. The big focus would be on the team dynamic as they all get along while going on their missions. Making Strong Guy believable would be a little bit of a challenge as his character increases and decreases mass any give moment. The CGI for bringing Multiple Man to life would also be very interesting.
