Page "Planet X (comics)" Paragraph 4

In the final showdown, Xavier is freed and the New X-Men unite to fight Magneto.

As Magneto murders Esme, Cyclops tells the grieving Emma that he's decided upon which woman ( Jean or Emma ) he loves but is interrupted by Magneto's attack and responds in kind, destroying his helmet as Fantomex frees Xavier.

Desperate for protection against Xavier's telepathy, Magneto grabs his " Xorn " mask and puts it on.

Having realized that Xorn is Magneto or at least believes himself to be Magneto, the X-Men attempt to unbalance him by calling him Xorn as they attack, complete with them begging " Xorn " to tell them why " he " betrayed the X-Men.
