The X-Men #56

In the Egyptian desert, the X-Men battle the Living Pharaoh and his men. The Pharaoh takes off with Alex and siphons off his mutant powers to turn himself into the Living Monolith. As the X-Men battle the Monolith, Alex turns the tables by taking back his power and more, stopping the Monolith and destroying the ancient temple where he has been trapped. Alex warns his friends to stay away as he has no control over the destructive powers coursing through his body.
