Merge:Changeling

The Changeling (Kevin Sydney) was a Marvel Comics character, and a member of the X-Men. Created by writer Roy Thomas and artist Werner Roth, he first appeared in X-Men #35 (August 1967).

The Changeling was a mutant shapeshifter. He was a short-lived X-Men adversary who, off-panel, joined the Professor X's efforts and died shortly after.

In the 1990s, he was reinvented as Morph in the X-Men animated series, which led to versions of the character being revived in the "Age of Apocalypse" alternate reality storyline and the series Exiles.

Character history
The Changeling originally worked for the villainous organization Factor Three. Following that group's defeat, it was revealed in X-Men #65 (February 1970) that he had reformed and unbeknownst to the X-Men was recruited by Professor X to replace him while he isolated himself to prepare for his fight against the Z'Nox. The Changeling, masquerading as Professor X, was killed in battle shortly after this in X-Men #42 (March 1968). It was not until a retcon in X-Men #65 that the X-Men learned it had not been the Professor who had died but the Changeling.

Although the Changeling seemed destined for obscurity for many years, he was revived in alternate continuities as Morph, first in the X-Men animated series, later in the Age of Apocalypse and Exiles.

Powers and abilities
Changeling is a mutant with the ability to alter his physical appearance at will to resemble that of any person he chooses. He also has limited telepathic abilities which (in the original timeline) were enhanced by Professor X. As a side effect he also gained limited telekinetic abilities. He is also a skilled actor.
