"There is always opportunity to improve your useless minions, Shredder . . . just as you 'improved' me."

"Yo, Rock! These dudes got hard candy shells!"

"Do not regret being defeated by me; my design made my victory inevitable."

"A war is coming that will spread from the streets of this city and engulf the entire world."

"Weak words. Weak actions! I have forever known what you fail to understand: Strength . . . Always . . . Prevails!"

"Family? We ain't no family, ya. Monsters got no kin."

"I am the chaos in the cracks, the vermin in the shadows. Everything fears me . . . everything except the rats."

"Let's crack 'em open and see what kinda goodies are inside!"

"You make it all so easy. Hmm, shall I freeze you in time forever? Devolve you back into four little sea dinosaurs and a monkey? Ooh! Or perhaps primal sludge."

"There is undoubtedly a fascinating story in how my old nemesis came to teach ninjitsu to four mutant turtles . . . perhaps I will let one of you live long enough to tell it!"

"You have a true warrior's spirit, you four, just like me. Except for the part where you hold back!"

"I suppose this is where I should be feeling pity . . ."

"Definitely feels good to be on the winning side of a beatdown."

"Threat detected. Eliminate."

"The future belongs to those who can take it."

"I don't know how you found your way into my war . . . but I promise you will rue the day you chose to oppose me."

"Think you can take on the apex predator o' dese parts? I dun think so, ya."

"The road we all trod—well, that you all trod—has one and only one destination."

"We wanna go bigger! We want the next fight to be freak against freak."

"You shall be forever stuck in the confines of time."

"Yes, come forward! Attack me if you will. When it is over, you will call me Master!"
