when did ultron first appear in the comics
Ultron The character initially appeared as an unnamed character in a cameo in The Avengers #54 (1968), with a first full appearance in Avengers #55 (1968). 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.[3] 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.[1] He liked the robot's malicious looking smile, showing this to Buscema.[3]
