I like:

-Uncanny X Force (SPOILER) Angel becomes Archangel, Phantom X has his outer nervous system with a mind of its own and Deadpool's in it. Nuff said
-Wolverine and the X Men

I like an old series called The New Mutants. There's a great story about Legion in one of them (SPOILER) aka Professor X's Son

There's too many! I wanna go and find the comic book version of Agents of Shield but will get distracted by the other 15 million series out there.
