I vote for the Xartans or Carbon Copy Men. They first appeared in JITM 90 and only made one other appearance in X-factor 32 posing as the avengers. They have the shape shifting and they also look like they are pale and decaying

As far as the Disir goes, they are all female so I doubt that they would be used.

Will be really interesting to finally find out who they are
