Iron Man 2.0 (2011 series) #5

As Rhodey notes, the ongoing Palmer Addley story has been interrupted by Fear Itself. We're deep in Iron Fist territory here, as revealed in the Immortal Iron Fist series. K'un Lun was revealed there to be one of the 7 Cities of Heaven, and Iron Fist was one of the Immortal Weapons, each the champion of one of the cities. John Aman, Prince of Orphans, is another of them. The other Immortal Weapons are also mentioned here, except Steel Phoenix who lost his position in the IIF series. During the series it was also revealed that there was an 8th city, which was a prison. Iron Fist and the other Immortal Weapons went on a mission in there, which John Aman refers to here. Since then Iron Fist has joined the New Avengers, and John Aman has worked with the Secret Avengers. This is the 1st appearance of Monkey King. In IIF the 8th city had a different ruler, who got deposed. We'll learn more about Monkey King and his relation to the legendary Chinese original in the Fear Itself: Monkey King 1-shot.
