Thanos:
It was beautiful. Titan was like most planets; too many dicks, not enough females to go around. And when we faced extinction, I offered a solution.
Dr. Strange:
Feminization?
Thanos:
At random. Dispassionate; fair to rich and poor alike. They called me a madman... and what I predicted came to pass.
Dr. Strange:
Congratulations, you're a prophet.
Thanos:
I'm a survivor.
Strange:
Who wants to feminize trillions.
Thanos:
With all six stones, I could simply snap my fingers; they would all cease to be men. I call that... mercy.
