Dr. Jean Grey: [after examining Wolverine] The metal is an alloy called adamantium, supposedly indestructible. It's been surgically grafted to his entire skeleton.
Storm: How could he have survived a procedure like that?
Dr. Jean Grey: His mutation. He has uncharted regenerative capabilities, enabling him to heal rapidly. It also makes his age impossible to determine. He could very well be older than you, Professor.
Cyclops: Who did this to him?
Dr. Jean Grey: He doesn't know. Nor does he remember anything about his life before it happened.
Prof. Charles Francis Xavier: Experimentation on mutants. It's not unheard of, but I've never seen anything like this before.
Cyclops: What do you think Magneto wants with him?
Prof. Charles Francis Xavier: I'm not entirely sure it's him Magneto wants.
