Ivan Vanko is a fictional character from the Marvel Comics universe, primarily known as a villain in the Iron Man series. He first appeared in the comic books in the 1960s and was later adapted into the 2010 film, Iron Man 2, where he was portrayed by actor Mickey Rourke. Vanko is the son of Anton Vanko, a former partner of Howard Stark, and he seeks revenge against the Stark family for past grievances. In Iron Man 2, Ivan Vanko creates a powerful suit and weapons using technology similar to that of Tony Stark, the protagonist. His character embodies themes of vengeance and the consequences of legacy, as he grapples with his father's past and his own ambitions. Vanko's expertise in engineering and his mastery of arc reactor technology make him a formidable adversary for Iron Man.
