Kevin Sydney

Kevin Sydney is a fictional character that has been a member of the X-Men in comic book stories published by Marvel Comics. Created by writer Roy Thomas and artist Werner Roth, the character first appeared in X-Men #35 (August 1967).

Kevin Sydney first appeared as Changeling, a mutant shapeshifter. He was a short-lived adversary for the X-Men who subsequently joined Professor X and died shortly after, making him the first member of the X-Men to die in action. The character was reintroduced as Morph in the 1990s for the X-Men Animated Series and later as part of The Exiles in 2001. Despite sharing the same alter ego, Changeling and Morph are distinctly separate characters and exist in different realities in the Marvel Multiverse.
