The following are quotes Shadow says during Sonic Adventure 2. If you care to listen, scroll down.
"My name is Shadow, since you were so kind as to release me, my master, I will grant you one wish..."
To Robotnik at Iron Gate.
"My name is Shadow the Hedgehog, I am the world's ultamite lifeform..."
To Sonic after he [Sonic]fights his first boss.
"Faker? I think YOUR the fake hedgehog around here. You're comparing yourself to me...HA! You're not even good enough to be my fake..."
Just before the first fight with Sonic.
"Before this is over...I'll show you the true power of CHAOS CONTROL!"
During the fight with Sonic.
"Maria...I still remember what I promised you..for all the people on this planet...I promise you...REVENGE!"
Just before Radical Highway.
"You never cease to surprise me blue hedgehog...I thought that capsule you were in exploded in space..."
Just before he fights Sonic again.
"So there's more to you than just looking like me...what are you anyway?"
Also before the Sonic fight on Ark.
"Oh I see, well you know, I can't let you live, your adventuring days are coming to an end!"
Likewise
"Leave this one to me..."
To Sonic and Knuckles
"I'll take care of this while you run and get the Chaos Emeralds!"
Again to Sonic and Knuckles
"HERE I COME YOU CREEP!"
To Bio-Lizard
"Is that what...Chaos Control is?"
To himself after watching Bio-Lizard using Chaos Control
"Playtime is over!"
To Sonic in 2 Playermode.
"Chaos Control!"
To himself when using Chaos Control
"Ultamite victory..."
When getting an A rank
"Well that wasn't so hard..."
When getting a B rank
"I guess I'm not at full power here"
When getting a C rank.
"I must destroy all the evil the profesor has created."
When beating the "Final Hazzard" with Shadow.
"Maria...it's better this way...this is the promise I made to you..."
When Shadow falls to Earth after the battle with Bio-Lizard, these are also his last words.
