"Eventually when something or someone is seen as too powerful... it is seen as a threat. (reaches out "hand" to gesture at Shadow, who has turned away, unnerved) And then the world becomes its enemy."

"Aren't I just incredible?! (When achieving an "A" Rank)"

"Don't you want to know what this is?"

"Shadow...? Even if you believe everyone in the world will be against you... know that I'll always remain by your side. Remember that."

"It's... It's so unfair! Shadow's always here to defend the world. Despite that..."

"If I had to choose between the world and Sonic, I would choose Sonic!"

"Well, now... I may not look it, but I'm a real treasure hunter. Unlike a certain echidna I know."

"I've found a Chaos Emerald!"

"My precious Chaos Emerald. You are all so beautiful. Your mysterious brilliance..."

"Just perfect! [After achieving an "S" rank]"

"For me, it's a piece of cake. (after getting an 'A' rank)"

"I guess I took a bit too long. (after getting an 'C' rank)"

"That was pretty good, I guess. (after getting an 'B' rank)"

"I will release you from the chains of your past."

"How can I call myself a treasure hunter? (after getting an 'D' rank)"

"Hmph. Perfect. (When achieving an "S" Rank)"

"So, Shadow, what do you think?"

"Can't complain. (after getting an 'S' rank)"

"I determine my own destiny."

"That's absurd. Whatever it is you want to do, you can do it alone."

"Don't try to deceive me. [Mephiles: What?] You have no desire for revenge. You only crave destruction. Your only lust is to fuel Iblis until there is nothing left of time itself."

"Ooch! (when she gets hurt)"

"Follow me if you want the truth."

"Guess that was alright. ("B" rank)"

"(while fighting Solaris) A super-dimensional being? Heh, this might even be a fair fight!"

"What's the point of all this? It'll never end!"

"(about Sonic) Certainly, it might've been possible... if he was still alive."

"Maybe I wasn't strong enough... (When achieving a "D" rank)"

"I found the means to seal Mephiles."

"Why fight at all? Why risk your life for those who will persecute you later?"

"The rift is getting bigger. There's no time left!"

"The 'I' of now absorbed your power through your shadow in the past. What may have worked ten years ago no longer does!"

"I'm your shadow... You can't even touch me..."

"Perfect Mission. (When achieving an "S" rank)"

"(sets Scepter of Darkness aside Elise) I already know what becomes of it in the future..."

"Who are you? And how do you know my name? (After Mephiles knows Shadow's name)"

"I am Shadow. Shadow The Hedgehog."

"Drown in darkness!"

"To discover what happened, it seems we must see what took place 10 years ago. Follow me if you want the truth. (Jumps into the portal)"

"Sink into darkness!"

"[after Silver finds him in Soleanna] Why does that matter to you? Unless you complete your task, your future will remain the same... forever."

"(After fighting Mephiles) So you say, if the world chooses to become my enemy, I will fight like I always have!"

"LET'S GET MOVING!"

"Good Performance. (When achieving an "A" rank)"

"[to Omega during first battle] You're just a nuisance... robot."

"(how to return) You need a space-time rift, but this requires a lot of energy.(After Sonic answers)Yes, but that alone is insufficient!"

"[taking damage in Boss Battle] Gah!"

"Just as a flower comes from a seed or a chicken comes from an egg, everything has an origin."

"Looking for me?"

"(to Eggman) Who is Mephiles? And why are you trying to capture him?"
