The reveal of Hank Hall as Monarch led to some controversy amongst the fan community; Monarch was originally intended to be revealed as Captain Atom, with clues in the story pointing towards this which had to be discarded when it was changed at the last minute. This change was due to the premature leaking of Monarch's identity. While Monarch was always supposed to be Captain Atom, this was supposed to be a secret. When Monarch's identity was prematurely leaked, DC decided to preserve the surprise of the story by switching Monarch's identity to that of Hank Hall.
