The Dark Phoenix saga

True to its namesake, the Phoenix rises, and Jean becomes one of the universe's most powerful entities.

But when she and the X-Men launch an assault against the clandestine organisation known as the Hellfire Club, she is manipulated into betraying her fellow mutants.

Jean is transformed into the Hellfire Club's Black Queen, and her life takes a deadly turn.

As her powers surge out of control, it becomes clear to all that the Phoenix must be stopped.

Some would destroy her regardless of the cost, but the X-Men desperately seek to defeat her without killing Jean in the process.

The fate of our world hangs on their success.
