Jason Wyngarde

Telepathic illusions: Wyngarde is a mutant with the power to cast illusions. He can psionically cause other people to see, hear, touch, smell, and/or taste things which do not actually exist. For example, he can seem to make a solid wall appear in an empty space. He can also cause people to see, hear, touch, smell, and/or taste real things in ways that they would no do naturally. For example, he can make himself look and sound like a different person or look and feel like a wall or even seem invisible. Since his power only affects the mind, his illusions cannot be recorded on film, tape, or other means. However, his power works so strongly on the mind that even if his victims know they are being subjected to an illusion, they will still react to the illusion as if it were real unless they can rid themselves of all suspicions that it is indeed reality. Hence, if Wyngarde creates the illusion of a wall, most people, even if they know it is an illusion, will still be unable to walk through it.
 * Limited mnemokinesis: Wyngarde can use his illusions to re-write the memories of impressionable minds, such as children. This process is often flawed.
