"Where other men blindly follow the truth, rememberSometimes, the badass doesn't need a longcoat, or a motorcycle, or a pair of shades. Sometimes, you just need the right words. Maybe you're a badass who's part of an order of badasses with similar goals. Or maybe you're a lone badass, and you've come up with a credo that explains who you are to others. Either way, you've got a Badass Creed, that sums up everything you are and what you believe in. See also In the Name of the Moon. If it only gets said once, it's probably a Badass Boast instead. Saying it to reinforce your goal or similar can have the same effect as a Theme Music Powerup, and can precede or punctuate a Crowning Moment of Awesome. Not related to the guy from Black Cat, even though he is a Badass Big Bad. Or the 4 star badass General Creed from Warhammer 40,000.
Nothing is true.
Where other men are limited by morality or law, remember
Everything is permitted.
We work in the dark to serve the light. We are assassins.
Nothing is true. Everything is permitted."
— The Assassin's Creed
