The Vision is a superhero appearing in American comic books published by Marvel Comics. Created by Roy Thomas and artist John Buscema, the character first appeared in The Avengers #57 (published in August 1968).[1][2][3] The Vision is loosely based on the Timely Comics character of the same name who was an alien from another dimension. The character is an android (sometimes called a "synthezoid") built by the villainous robot Ultron created by Hank Pym. Originally intended to act as Ultron's "son" and destroy the Avengers, Vision instead turned on his creator and joined the Avengers to fight for the forces of good. Since then, he has been depicted as a frequent member of the team, and, for a time, was married to his teammate Scarlet Witch. He also served as a member of the Defenders, and is the father of Viv Vision.
