Today's Fact
Checked against independent sources — the issues are cited below.
The most consequential body Charles Xavier ever lived in was not the one he was born in. A Brood Queen had secretly implanted him with an embryo, and in Uncanny X-Men Vol. 1 #167 (1983) the transformation finished in front of his horrified students: the professor's body warped into a young Brood Queen, and Xavier, surfacing for one lucid moment inside the monster, begged Cyclops to kill him before the creature took full control.
Cyclops refused, and the Starjammers offered a stranger mercy. Moira MacTaggert and the medic Sikorsky could not reverse the transformation, but they held a tissue sample Xavier had given the Starjammer before his infection. From it they grew a healthy clone body and transferred his consciousness across, leaving the Brood Queen husk behind. Technically, the Charles Xavier of every X-Men story since 1983 has been that clone.
The new body came with one astonishment: unbroken legs. Xavier rose and tried to walk for the first time in years, then folded in agony, because a mind that had spent decades screening out the pain of crushed legs kept feeling it in limbs that were never injured. The clone could walk. Teaching the man inside it to believe that took considerably longer.
Why It's Obscure
His students would not kill him, so they replaced him instead, and the replacement body arrived with working legs and phantom pain.
