Possessed by an Ancient Evil! (Volume 1, Issue #85)
Skids, captured and held in a Latverian dungeon, falls under the spell of the ancient demon Pandemonia. Now under her control, Skids leads her back to X-Force headquarters, where she begins to take over the minds of the other members.

Bedlam, Cannonball, and Dani Moonstar return and are attacked by their mind-controlled teammates. Rather than fight them, Cannonball wisely escapes with Bedlam and Moonstar and takes them to an occult bookshop, hoping to find more information about Pandemonia. It doesn't go well, and they are thrown out.

Luckily, they are directed to the sorcerer Jennifer Kale, who breaks Pandemonia's mental hold on X-Force, and the team banishes her to her own dimension.
