From The Green Lantern:
Hal Jordan: The one thing a Green Lantern is supposed to be is fearless. "Fearless" is the job description.
From Monsters University:
Sulley: (to Mike) You're not scary. Not even a little bit. But you are fearless...
Gusteau: You must be imaginative, strong-hearted. You must try things that may not work, and you must not let anyone define your limits because of where you come from. Your only limit is your soul. What I say is true. Anyone can cook, but only the fearless can be great.
From Star Trek: Into Darkness:
Khan: Mr. Spock. The mind of the Enterprise. The fearless genius who ensures a calm force of intelligence guides their every mission.
From Ender's Game:
Ender Wiggin: Fifty years ago an alien force known as the Formics attacked Earth. Tens of millions died. It was only through the sacrifice of our greatest commander that we avoided total annihilation. We've been preparing for them to come back ever since. The International Fleet decided that the world's smartest children are the planet's best hope. Raised on war games, their decisions are intuitive, decisive, fearless. I am one of those recruits.
