- Robotnik/Eggman: [Sonic arrives at the ARK research facility where Robotnik has Tails and Amy captive] Let's take care of buisness first, shall we Sonic? Hand over the Chaos Emerald slowly and then we'll talk about your girlfriend. That is if you really care for her.
- Sonic: [quietly] Handing over the fake emerald. I can kill two birds with one stone.
- [Tails nods]
- Robotnik/Eggman: Put the emerald down right there and back off.
- Sonic: [Sonic smiles and walks] You've turned into a big time villian doctor.
- Eggman: [Eggman presses a button and causes a glass tube to fall over Sonic] You thought you could trick me with that fake emerald didn't you?
- Tails: So, how did you know it wasn't the real one?
- Sonic: Tails!
- Robotnik/Eggman: Because you just told me, fox boy!
- Shadow: You never cease to surprise me, blue hedgehog. I thought that capsule blew up with you in it.
- Sonic: What can I say? I die hard.
- Rouge: Do you think the Professor really created him... Shadow... to bring out the revenge on humans?
- Sonic: He was who he was. A brave and heroic hedgehog who gave his life to save the planet. Shadow the Hedgehog...
- Rouge: I guess you're right...
- Shadow: You're adventuring days are coming to an end.
- Rouge: What are you babbling about? You call yourself a hunter? Attacking a lady? Shame on you.
- Knuckles: What kind of lady goes around stealing gems anyway?
- [Sonic and Tails break in the President's limo]
- President: Wha...? What the heck's going on here?
- Shadow the Hedgehog: If you want to live, you will keep the emeralds where they are. The fake emerald is good enough for you.
- Rouge: Do you actually think that you're the real Shadow?
- Shadow the Hedgehog: No doubt.
- Rouge: Even your memories might not be real, you know.
- Shadow the Hedgehog: Even if my memories are not real, it's still me... Shadow. And I have to keep my promise to Maria. That's the only thing that matters to me now...
- Shadow the Hedgehog: My name is Shadow. I'm the world's ultimate life form. There's no time for games. Farewell.
- Robotnik/Eggman: [seeing the capsule launch into space and explode presumably with Sonic inside] Farewell Sonic, my admirable adversary.
- [the police are braking their cars trying to catch Shadow]
- Shadow: How pathetic.
- [He closes his eyes and flashes bacck to 50 years ago. a Gunshot is heard]
- Shadow: [in flashback] Maria.
- Maria: Shadow, I beg of you please do it for me,for the all the people on that planet. Sayonara Shadow the Hedgehog.
- [back to present]
- Shadow: Maria. I still remember what I promised you. For the people of this planet I promise you... REVENGE.
- Dr Robotnik: [during Crazy Gadget] Sonic! What's taking so long? If you don't get here soon, she WILL die!
- Shadow the Hedgehog: You never cease to surprise me, blue hedgehog. I would have sworn you went down with that capsule. Just who are you?
- Sonic the Hedghog: What you see is what you get! I'm a guy with a love of adventure and a need for speed!
- Shadow the Hedgehog: I see. But you realise I can't let you live.
- [Knuckles is walking around]
- Knuckles: I feel some strange energy.
- [a green glow appears and Sonic teleports in]
- Knuckles: Hey Sonic.
- Sonic: I wasn't sure if I could pull that one off. Somehow I managed to use the Chaos Control.
- Knuckles: Chaos Control? Are you OK?
- Sonic: I'm worried about Tails and Amy. I hate to ask, bu could you help them? This is our last chance. I got it before the cannon fires I'll slam dunk it in there.
- Shadow: Maria, this is what you wanted, right? This is the promise I made to you...
- Gerald Robotnik: Now all of you ungrateful humans will feel my loss and despair.
- [Sonic and Tails jump in the President's limo from its roof]
- Dr. Robotnik: Sonic? What are YOU doing here?
- Sonic: Eggman Empire. Yeah, right.
- President: What the heck's going on here?
- Rouge: So you did your homework, huh? I would say that's an invasion of someone's privacy.
- Shadow: I could say the same for you.
- Robotnik/Eggman: [after seeing that his attempt to kill sonic has failed] You're pretty persistent for a hedgehog aren't you? Still alive, huh?
- Sonic: Hah! Just letting Knuckles pilot the shuttle on the way over here was more dangerous than you could ever be!
- Shadow: Here I come you creep!
- Rouge: [while Sonic and Shadow are fighting the Final Hazard] Can you hear me, Sonic, Shadow? Everyone here is rooting for you! Good luck and give him trouble!
- Robotnik/Eggman: [to Sonic during the Crazy Gadget stage] You're too slow. Sonic, if you don't come here, she WILL die!
- Shadow the Hedgehog: That blue hedgehog again, of all places.
- Sonic the Hedghog: I found you, faker!
- Shadow the Hedgehog: Faker? I think you're the fake hedgehog around here. You're comparing yourself to me? Ha! You're not even good enough to be my fake.
- Shadow the Hedgehog: [after the capsule containing Sonic has been ejected into space and exploded] I guess he was just a regular hedgehog after all.
- Knuckles the Echidna: [coming out of the sewers] Hey guys long time no see.
- Amy Rose: Move aside Knuckles
- Sonic the Hedghog: [to Eggman] Just letting Knuckles pilot the ship over here was more dangerous than you could ever be.
- Shadow the Hedgehog: [Walking] You never cease to surprise me blue hedgehog, I thought that capsule you were in exploded in space.
- Sonic the Hedghog: [Walking] You know, what can I say? I die hard.
- Shadow the Hedgehog: [Running] So there's more to you than just looking like me. Just what are you anyway?
- Sonic the Hedghog: [Running] What you see is what you get. I'm just a guy who loves adventure. I'm Sonic the Hedgehog!
- Shadow the Hedgehog: [Sprinting] I see, but you know I can't let you live. You're adventuring days are coming to an end.
- Dr Robotnik: [after getting an "A" ranking on any stage] Now you know why I am the best!
- Robotnik/Eggman: [when Sonic arrives at the final room of Crazy Gadget] Well done, Sonic. But you'll never leave this room alive! Ha-ha!
