Avengers, The (1963 series) #11

Kang states that he is a descendant of Dr. Doom

When the Avengers grant Iron Man a leave of absence he is already absent. They just assume he is investigating Tony Stark's death. Tony's was assumed after Mandarin's ray struck the Stark estate from space in Tales of Suspense #61. Mandarin then took Iron Man away for the duration of ToS#61-62. Kang fought the Avengers in #8, and will fight them again next in #23-24. His claim to be descended from Dr Doom is part of the confusion surrounding his origin. In Fantastic Four Annual #2 it was suggested they might be the same person at different ages. The accepted version nowadays is that he is descended from Reed Richards father Nathaniel, who went into an alternate timeline. The Spider-Man robot claims that Iron Man has been captured by the Masters of Evil, who have bedevilled the Avengers in one form or another in #6,7,9,10. The robot directs them to the wrong part of South America, because the Masters are based in the Amazon. Spider-Man has already met Giant-Man and Wasp in Tales to Astonish #57, although they don't mention it here. The real Spider-Man will be asked to join the Avengers in Amazing Spider-Man Annual #3 (but he'll turn the offer down).
