Sandra: You are really going through with this.
Claire: They killed Dad, they're never going to leave us alone.
Sandra: You do realize what'll happen to us if you tell everyone what we can do.
Claire: Yes. No more running, no more hiding, no more secrets.
Sandra: Your dad couldn't take down this company, Claire, what makes you think you can?

Sandra:Claire! Thank God. I was so worried. Are you okay? Because if you are, you are so grounded!

Stephen Canfield: I won't be a monster!

Sylar: [Whilst attacking Sue Landers; he is about to slice her head open.] Don't worry. It won't hurt a bit. [Sue uses her ability to see he is lying. He shrugs.] Got me. That's a lie.
[He kills Sue and leans over her on the floor.]
Sylar:I almost forgot how good this feels...
[Sue's friends burst into her office with balloons and gifts.]
Friends: Happy Birthday!
[They see Sylar kneeling on the floor by Sue's corpse, covered in blood. He turns to them.]
Sylar: Cake!

Sylar: (Noah shoots him six times. Sylar lies beside the wall, while the bullets all get ejected from his body.) Ouch. I got that from your Claire
Noah: You son of a bitch!

Sylar: (after testing his restored powers by pulling a spinach can to himself) I'm back.
Season 3 (Volume 3: Villains)

Sylar: [opening voiceover]] On the sixth day, God created Man in His own image, now it's up to us to figure it all out. Right...wrong...good...evil...in each of us is the capacity to decide what drives our actions. So what is it, then, that makes some choose selflessness, the need to devote oneself to something greater, while others know only self-interest? Isolating themselves in a world of their own making? Some seek love, even if only unrequited, while others are driven by fear and betrayal. There are those who see their choices as dark proof of God's absence while others follow a path of noble destiny. But in the end, good, evil, right or wrong...what we choose is never what we really need. For that is the ultimate cosmic joke, the real gift that God has left behind.

Sylar: [Shapeshifted] You really did a great job, sir. [He reaches to shake the President's hand. They touch, and Sylar's face morphes between many people. The handshake turns into a firm grip and a needle is thrust into Sylar's neck as Peter reveals himself and pulls their faces close.]
Peter: Bet you didn't think I took that one from you.
[Sylar passes out in the back seat of the President's limo]

Sylar: Boom...

Sylar: Empathy? What makes you think I'm capable of that?

Sylar: Everyone dies, well, almost everyone. Papa Petrelli, Mama Bennet, Mr. Muggles... what's your brother's name again? Larry?
Claire: Lyle.
Sylar: Right... he's gonna die too.

Sylar: Everything that I've been working for, everything I had, is gone.

Sylar: Haven't I killed you before?
Peter: Didn't take.
Sylar: [chuckles] You think I'm gonna let you ruin it all? Take all the glory? [Parkman shoots at Sylar, but he stops the bullets and reflects them back.] Did you really think you could stop me?

Sylar: Hi. My name is Sylar. It's been about six weeks or so since I've seen my body, and I want it back.

Sylar: Hmm, looks like you dropped something. [Sylar picks up a Ninth Wonder cartoon.] A comic book that predicts the future. What will they think of next? [Sylar turns to page showing Hiro stabbing him.] You're kidding. This is how Isaac thought I'd die? Stabbed by a silly little man?
Ando: Hiro is not silly!
Sylar: You should've seen the look on his face when he tried to kill me.
Ando: You cannot take my brain.
Sylar: Please. What would I want with your brain?
