The New Mutants expanded team
We get to see Sunspot in Days of Future Past.
That's not enough.
I want to see: Mirage, Cannonball, Warlock, Cypher, Magic, Magma, Karma, Meltdown, Skids, Rusty.
I hope that these characters show up by the next film.
If the next film is in the 1980s, that's the New Mutants home decade, anyway.
