- Chao Café Kid: [to Tails] Are you Detective Pikachu?
- Sonic: Yes, he is!
- Knuckles: [laughs] He does look like a Pokémon! Pika Pika!
- [Sonic, Tails and Knuckles notices that there is a black and red hedgehog named Shadow]
- Sonic: Whoa! Are you guys seeing this?
- Tails: He looks just like you!
- Knuckles: Impossible!
- Shadow: You're a colourful bunch.
- Sonic: Excuse me, why do you look like me?
- Shadow: I don't look like you, you look like me. Why do you look like me?
- Sonic: Hey, you know what? I'll ask the questions, new hedgehog. Who are you? Why do you look like me?
- Shadow: This is a waste of time. Walk away, before you get hurt.
- Sonic: Whoa, whoa, whoa. Easy, buddy.
- [pulls out of the handcuffs]
- Sonic: We don't want to fight you.
- Knuckles: Actually, Sonic, I would like to fight.
- Sonic: [pushes Knuckles away] Not now.
- [Knuckles grunts]
- Sonic: Why don't you just stop throwing cars at us for a second, and come down here to talk.
- Shadow: You jumped out of a G.U.N helicopter. There's nothing to talk about.
- Knuckles: All right then, enough!
- [charges to fight Shadow]
- Sonic: Knuckles, no!
- Knuckles: Let us talk with our fist!
- [jumps forward, aiming a fist at Shadow, who turns around. Everything slows down as Shadow swiftly teleports right in front of a surprised Knuckles. Shadow grabs his hand and twists it. Knuckles shouts in pain before Shadow lifts him up and kicks him into the air]
- [after chasing the masked motorcycle man to a pier]
- Sonic: Hold it right there, Tokyo Drift. Who are you?
- [He takes off his helmet to reveal he's Agent Stone]
- Knuckles: [gasping] It's the goat milker!
- Agent Stone: [imitates Knuckles] It's the goat milker! Relax. I'm not here to fight.
