Vision is a superhero under Marvel Comics in the United States, first appearing in the 57th issue of "The Avengers" (October 1968). There are three generations in total, and Vision, which has been active in comics for a long time, is the second generation Vision. Vision is a cyborg created by Ultron to deal with the Avengers by transforming the body of the first World War II hero, Thunderbolt, and activating it with the brainwaves of a divine being. After multiple battles with the Avengers, Vision was moved by the humanity of the Avengers members and betrayed Ultron to join the Avengers. He met the Crimson Witch, who was also a member of the Avengers, and the two fell in love and became husband and wife.
