ROGUE

Rogue's touch usually takes one person's powers and memories. In 2007 it took a planet. After the villain Pandemic infected her with Strain 88 — a virus that removed every limit on her absorption — Rogue confronted the Hecatomb, a Shi'ar superweapon that had consumed the minds of eight billion people. To stop it, she touched it — and absorbed all eight billion minds at once (X-Men vol. 2 #199–#200, 2007, by Mike Carey).

The minds did not merge or fade. Emma Frost, entering Rogue's head in X-Men vol. 2 #200, found all eight billion still separate, complete, and mostly terrified — with Rogue's own personality just one voice in the crowd, sometimes in control and sometimes drowned out entirely. Beast could find no drug or phage that touched Strain 88.

Rogue kept functioning as an X-Man with a planet screaming inside her before finally slipping into a coma. She was only purged during Messiah Complex, when Mystique pressed the infant Hope Summers' hand to Rogue's face — Hope's touch reset her powers and evicted the eight billion, at the risk of the baby's life. Rogue woke up furious at her mother, and in full control of her absorption for the first time in her life.
