29. X-Men vs. Dark Phoenix
After their battle with the Hellfire Club in Uncanny X-Men #135, Phoenix has officially flipped her lid and become Dark Phoenix.
The X-Men battle against her in Uncanny X-Men #135, but she casts them aside like they’re children compared to her might. After the fight, the ex-X-Man, Beast (now an Avenger) comes to help the team out in Central Park where Dark Phoenix left them.The X-Men regroup and decide to try to get her into a MacGuffin device, but she ruins that plan easily and once again kicks all their collective behinds. Cyclops is left standing, and he tries to appeal to the human essence within Dark Phoenix, and he begins to break through, but Professor X never turns down an opportunity to attack someone, so he begins a telepathic assault on Dark Phoenix which is a major battle of the minds.
Ultimately, with the help of the Jean Grey persona within Dark Phoenix, Xavier is able to shut down Jean’s telepathic powers and silence Dark Phoenix…for now!
