X-Men: The Last Stand2006

[The Brotherhood of Mutants continues to liberate mutants, checking people on their list but Mystique Loses Her Powers]

Pyro:
[reads the list] "Cain Marko. Solitary confinement." and check this out: "Prisoner must be confined at all times. If he builds any momentum, no object can stop him."

Magneto:
How fascinating. [opens his cell where Cain's limbs were bounded in the cell.] What do they call you?

Juggernaut:
"Juggernaut".

Magneto:
I can't imagine why?

Juggernaut:
Are you going to let me out? I need a pee! [Magneto removes his restraints and the Juggernaut jumps out of his cell. Cain's force of his jump awakens one of the prison truck guards, who was unconscious earlier.]

Pyro:
Nice helmet.

Juggernaut:
Keeps my face pretty.

Magneto:
[to Juggernaut] I think he'll make a fine addition to our army.

Pyro:
Yeah.

[Mystique sees light from the gun aimed at Magneto.]

Mystique:
NO!

[Mystique steps in the way and is shot with the Cure; falls; Magneto grabs the dart gun; Pryo blasts the guard out; Mystique begins to seizure; hair turns black and blue skin disappears; turns completely human, lays naked in shock and devastation]

Magneto:
You saved me. [begins to turn away]

Mystique:
[to Magneto; pleadingly] Erik.

Magneto:
'I'm sorry, my dear. You're not one of us anymore.
