"The future: a dark, desolate world. A world of war, suffering, loss on both sides. Mutants, and the humans who dared to help them, fighting an enemy we cannot defeat. Are we destined down this path, destined to destroy ourselves like so many species before us? Or can we evolve fast enough to change ourselves... change our fate? Is the future truly set?"
—Charles Xavier, initial lines
"It's not their pain you're afraid of. It's yours, Charles. And as frightening as it can be, that pain will make you stronger. If you allow yourself to feel it, embrace it, it will make you more powerful than you ever imagined. It's the greatest gift we have: to bear their pain without breaking. And it comes from the most human part of us: hope. Charles, we need you to hope again."
—Charles Xavier to his younger self
"All those years wasted fighting each other, Charles... to have a precious few of them back."
—Magneto
"The past: a new and uncertain world. A world of endless possibilities and infinite outcomes. Countless choices define our fate: each choice, each moment, a moment in the ripple of time. Enough ripple, and you change the tide... for the future is never truly set."
—Charles Xavier, last lines
"Just because someone stumbles and loses their way, doesn't mean they are lost forever."
—Charles Xavier later said to Doctor Strange in an alternate universe.
