John Myers: My uncle used to say that we like people for their qualities but we love them for their defects.
[talking to Liz, re: his appearance]
Hellboy: I wish I could do something about this. But I can't. But I can promise you two things. One: I'll always look this good.
[Liz laughs]
Hellboy: Two: I'll never give up on you... ever.
Liz Sherman: I like that.
Hellboy: Good.
Abe Sapien: [while stitching up Hellboy's forearm] How long did he touch you?
Hellboy: I don't know? About 5 seconds?
Abe Sapien: [pulls three eggs out of his forearm] Touched you five seconds, laid three eggs.
Hellboy: Didn't even buy me a drink.
Liz Sherman: In the dark I heard your voice, what did you say?
Hellboy: I said, "Hey, you, on the other side - let her go. Because for her I will cross over, and then you'll be sorry!"
[Hellboy grabs Sammael's tongue]
Hellboy: Second date, no tongue!
Hellboy: Hey Myers, you're a talker. What's a good word, a solid word for "need"?
John Myers: Well, "need" is a good, solid word.
Hellboy: Nah. Too needy.
[about his Rubik's Cube]
Abe Sapien: Listen, I'm not much of a problem solver. Three decades... and I've only completed two sides.
Abe Sapien: Remind me why I do this again.
Hellboy: Rotten eggs and the safety of mankind.
Abe Sapien: Ah!
[last lines]
John Myers: "What makes a man a man?" a friend of mine once wondered. Is it his origins? The way he comes to life? I don't think so. It's the choices he makes. Not how he starts things, but how he decides to end them.
Hellboy: I'm fireproof, you're not.
Hellboy: [carrying the torso of a re-animated corpse over his shoulder] How you doing back there, Ivan?
Ivan Klimatovich: [in Russian] If I still had legs, I'd kick your ass!
Hellboy: [to agent] Could you hold this guy for a while? He is so negative.
Abe Sapien: [about Sammael] Harbinger of Pestilence, Seed of Destr...
Hellboy: Cut to the end, will ya? How do I kill it?
Abe Sapien: Hmm, doesn't say.
Hellboy: Look, Sammy, I'm not a very good shot...
[holds up his huge revolver]
Hellboy: ...but the Samaritan here uses really big bullets.
Abe Sapien: [after probing the sealed door] Behind this door, a dark entity. Evil, ancient and hungry.
Hellboy: [sighs] Oh, well. Let me go in and say hi.
Kid on Rooftop: Just go down there and tell her how you feel.
[Hellboy is silent]
Kid on Rooftop: My mom always says...
Hellboy: It's not... it's not that easy. Plus, you're nine. You're not old enough to be giving me advice.
[repeated line]
Hellboy: Aw, crap.
[holding his stone hand up to a moving car]
Hellboy: Red means stop!
[punches the car into the air]
Hellboy: [hears the alarm in his room, to Myers] Hey. Hey. Hey. They're playing our song.
[Hellboy is going back to confront Behemoth]
John Myers: Are you going to be... okay? Alone?
Hellboy: How big can it be?
[a tentacle grabs Hellboy and pulls him back]
