Recent X-Men comics have seen Bastion, Mojo, Shadow King, Selene and William Stryker back again, and Emma Frost returning to her villainous roots. I think the antagonists are always a huge part of the story, so I'm curious which X-Men villains we've seen in the past you'd like to see make a comeback. Who would you like to see again in the X-Men comics?
For me, I really want to see Exodus and the Acolytes (particularly Frenzy, Random, Unuscione, Tempo and Amelia Voght, though I'm open to new/alternate members + I want Elixir to join)
Also, Madelyne Pryor & the Sisterhood: Last time we saw the Sisterhood there was a tease of something new, but we haven't seen 616 Madelyne Pryor since. I'd like to think she's gathered some formidable female mutants from across the MU with a range of aesthetics and powersets. (Astra, The Mastermind sisters, Skein, Chimera, Dragoness, Tithe, Omega Black, Phantazia etc.)
