"This is terrible! According to the data, the princess died when she was kidnapped by Eggman! Apparently Eggman's battleship exploded! The data of this incident was... two days after the Festival of the Sun!"

"Well, not bad! (get an "B" rank)"

"Hmph. That took longer than I thought. (get a "C" rank)"

"Well, that wasn't...too bad. (get a "B" rank)"

"Shoot! I still got a ways to go... (get a "D" rank)"

"Alright! (when receiving an "S" rank)"

"I'll take care of it!"

"A Chaos Emerald! You've already found one!"

"(landing in isolated base in the future) Boy, do I feel dizzy... Where are we?"

"WHOA! My head's spinning!"

"GREAT! I did it, Sonic! (when getting an "S" rank)"

"That was incredible! (When getting an 'S' rank)"

"Too easy! No sweat! (When getting an 'A' rank)"

"The whole city's on fire!"

"That tornado's carrying a car!"

"Piece of cake! No sweat!"

"Darn! We're not gonna make it. Let's speed up!"

"If I find the one issuing orders and defeat him, I can defeat everyone at once."

"If you have time to worry, then run!"

"That felt good. (when receiving an "A" rank)"

"I heard you tried to rescue their princess from Dr. Eggman."

"WHHHHHHOOOOOOOAAAAA! (Falling into an abyss)"

"This is it, Eggman! Prepare for another defeat!"

"Elise is on that battleship? Wait up, we're coming!"

"(Take too long in finishing a stage or get a 'D' rank) Man! Today's not my day!"

"Nice smile."

"Sonic the Hedgehog may share its name with the Genesis original, but this game is even more broken than most of the other recent Sonic games have been. [...] Only the most blindly reverent Sonic the Hedgehog fan could possibly squeeze any enjoyment out of Sega's latest adventure. This platformer is a mess from top to bottom, and any of the occasional moments that don't feel somehow broken only serve to make the game's other flaws appear that much bigger."

"I'll make sure to change Elise's fate. And that in turn should change your future, too."

"I determine my own destiny."

"Hmph. Not even a challenge. (When achieving an "A" Rank)"

"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."

"So, Shadow, what do you think?"

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

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

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

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

"What did you think of my beautiful technique? (after getting an 'S' rank)"

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

"I've found a Chaos Emerald!"

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

"Hmph. He finally shows up again and then he leaves before even saying, "Hello." Well, it seems his little trip hasn't changed him."
