Shadow the Hedgehog: I assure you Sonic, I am no imposter. I posses far too much power to be anything but the real fake.
Amy Rose: Throughout history, behind every great hero, there's a great woman guiding him.
Dr. Eggman: It's not easy being an evil madman.
Sonic the Hedgehog: I don't get involved in fights I can't win.
Dr. Eggman: Grandfather, how could you? Destroying the planet is one thing, but destroying your own grandson....
Christopher 'Chris' Thorndyke: Hey, Knuckles. Where'd you get the robot?
Knuckles the Echidna: Well, it's not exactly mine.
Knuckles the Echidna: You'll fail, unless you have me along. I can't wait to see the look on Sonic's face when he finds out that I helped defeat Dr Eggman while he missed out on the glory. That'll mess with his ego.
Rouge the Bat: You have a serious inferiority complex, Knuckles.
Knuckles the Echidna: Huh? I have a what?
Rouge the Bat: Oh, never mind.
Amy Rose: Hmph. I bet you want to thank Sonic for saving your life and to apologise to him for believing all the lies Eggman told you about him. You're just too proud.
Knuckles the Echidna: Zip it.
Sonic the Hedgehog: Kids, don't use formula one race cars to chase hedgehogs.
Sonic the Hedgehog: Whaddaya say, Knuckster?
Knuckles the Echidna: The name's Knuckles, wise guy.
Sonic the Hedgehog: See? It worked out okay after all.
Knuckles the Echidna: Oh, sure. Apart from Eggman getting the Chaos Emeralds, it worked out just perfect.
Dr. Eggman: I'll have you know, the Egg Beam Cannonball is engineered to hit the bullseye every time.
Decoe: But Sonic is a hedgehog, not a bull.
Dr. Eggman: I'll try to forget you said that.
Shadow the Hedgehog: You traitor.
Knuckles the Echidna: I always wanted to shadowbox.
Shadow the Hedgehog: As you wish.
Knuckles the Echidna: Knuckles never runs away from a fight.
Knuckles the Echidna: One day they love us because we're unique. The next we're in jail because we're different.
Dr. Eggman: Even egg-centric geniuses like myself have hearts.
Sonic the Hedgehog: That so?
Dr. Eggman: I kid you not.
Mr. Tanaka: Maybe Mr. Knuckles is simply afraid to play a game of baseball.
Knuckles the Echidna: Afraid? I'm not afraid of anything.
Sonic the Hedgehog: Good! Then you'll play, huh?
Dr. Eggman: Goodbye world domination, hello shuffleboard.
