It has been confirmed through set photos that the terrorist organization A.I.M. will be a part of the movie. Comicbook.com also reported on Wang Xueiqi possible playing the Radioactive Man in Iron Man 3, but other reports have suggested Wang Xueiqi would not take on the green skin or actual name of Radioactive Man.
Of course, just like the Mandarin was denied in the beginning, it could be that Radioactive Man was just denied to keep fans off guard. We've seen two sources from the 2013 London Toy Fair suggest that Radioactive Man is part of the Iron Man 3 Lego sets. Brick Heroes lists Radioactive Man with a question mark as part the Iron Man 3 Malibu Mansion Attack Lego set, and Brick Fanatics describes the Iron Man 3 Malibu Mansion Attack Lego set as including “Tony Stark, Ironman mk42, Pepper Potts, Mandarin and pale green bad guy we were not allowed to know name of.”
Iron Man 3 is set to be released in theaters in the United States on May 3, 2013.
