Changeling was a mutant with the ability to alter his physical appearance at will to resemble that of any person he chose. He was given limited telepathic abilities by Professor X, and as a side effect, he also gained limited telekinetic abilities.

Metamorph: He can psionically alter the formation of his biological cells at will. As a result he can cause himself to look and sound like an exact duplicate of any human, humanoid, or semi-humanoid being of either sex, wearing virtually any kind of clothing.

Telepathy: He is able to read minds and project his own thoughts into the minds of others within a limited radius.

Psionic Blasts: He can project psionic force bolts which have no physical effects but which can affect a victim's mind so as to cause the victim pain or unconsciousness and can even kill an adversary.

Telekinesis: Possesses telekinetic abilities enabling him to manipulate matter on a low level with the energy of his thoughts.
