Ultron was created by writer Roy Thomas and artist John Buscema . Thomas, who has acknowledged he finds naming characters difficult, said he liked the - tron suffix and went from there . Thomas said the idea of the character and his appearance were heavily based on Makino, an obscure robotic villain who appeared in an issue of the Captain Video comic book . He liked the robot's malicious looking smile, showing this to Buscema . </P> <P> Although Ultron first appears in Avengers #54 (1968), the character is disguised for the majority of the issue as the "Crimson Cowl", with his face only revealed on the last page of the issue and no name given to the character . The character leads the Masters of Evil against the Avengers, having hypnotized Edwin Jarvis into working for him . In the following issue Avengers #55 (August 1968), the character is identified as Ultron - 5, The Living Automaton . In Avengers #57--58 (October--November 1968), a flashback sequence revealed that Ultron created the "synthezoid" Vision as a weapon to destroy the Avengers . The Vision--having Wonder Man's brain patterns--destroys Ultron with the Avengers' aid . </P>
