X-Men: Phoenix – Warsong is an American five-issue comic book limited series released in 2006, beginning in September. The series is a sequel to X-Men: Phoenix - Endsong. It is written by Greg Pak and illustrated by Tyler Kirkham. In an interview, Author Greg Pak said "This is not a Jean Grey resurrection story." A hardcover "Marvel Premiere Edition" was released on July 18, 2007, compiling all five issues. Plot The story revolves around the Stepford Cuckoos and includes the team from Astonishing X-Men. In the first issue, a piece of the Phoenix Force attaches itself to the three remaining Stepford Cuckoos, amplifies their telepathic power, and gives them the power of telekinesis. With their newfound abilities, the girls overcome Emma Frost's psychic detention and resurrect their deceased sisters Esme and Sophie.

The two deceased Cuckoos, now undead but still decayed, appear and are more aware of the unfolding events than the Three-In-One. In the third issue, it was revealed that Emma's ova were the genetic templates used to clone the hundreds of identical telepaths; including the Five-In-One. They were harvested from her by John Sublime, the Director of Weapon Plus, at some point during her coma following the death of the original Hellions. The clones begin to refer to Frost as "mother", a title which she later accepts. It was also shown that Celeste now wields the Phoenix Force. The fourth issue reveals the Cuckoo's original purpose. It is shown that the cloned sisters serve as telepathic antennae, their sheer number
