Nelson Rockefeller was depicted as the President of the United States of America on Earth-721. Like Earth-616, Earth-721 is subject to the Sliding Timescale that makes time advance slower so as not to prematurely age. As such, Rockefeller should be considered a topical reference relative to the date of the publications he appeared in. At the time of his first appearance, the real Rockefeller was Vice President of the United States next to Gerald Ford.
