Changeling is one of the least developed X-Men so wringing a paragraph out of talking about him isn’t easy.
He originally was a villain working with Factor Three, an organization that also weaponized Banshee, but he was defeated and betrayed the evil organization. He was a shapeshifter, if that wasn’t clear from the name, by the way. But Changeling would soon discover that he was dying of cancer and would arrive at the X-Mansion seeking help. And Xavier, who is a huge jerk, saw this dying man as a golden opportunity.
See, Xavier had detected an alien invasion from a race called the Z’Nox and needed to prepare SO HE HAD A PLAN. He would go prepare and Changeling would take his place with the X-Men, while pretending to be him. I have no clue why he did this and didn’t just tell his students all of this. Changeling was killed, and the X-Men buried him, still thinking he was Professor X. God that’s sad.
