"[Closing narration] 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."

"Remember who you are! [Throws Hellboy the rosary]"

"Are you gonna be okay? Alone?"

"Hellboy– He's real!"

"[Liz Sherman: In the dark, I heard your voice, what did you say?] I said, "Hey, you on the other side – let her go. Because for her, I will cross over, and then you'll be sorry.""

"[To Kroenen] You killed my father! Your ass is mine!"

"Hey, Myers, you're a talker. What's a good word, a solid word for "need"?"

"It's not– It's not what you think. Plus, you're nine. You're too young to be giving me advice."

"[Watching Meyers and Liz] No cream and milk, moron. She takes it black. Told ya! Wait, she took his picture! DAMN!"

"[To the train conductor, who is beating him in the head with a fire extinguisher to try and knock him off the train] Hey! I'm on your side! [Train Conductor: Sure.] [The train conductor hit Hellboy in the head with a fire extinguisher, knocking him off the train]"

"[While beating Sammael with a payphone he had ripped off a wall] It's for you! You shouldn't– hurt– people!"

"Gonna be sore in the morning."

"[About Liz's new nickname] "Sparky"? Who came up with that? Myers?"

"Damn! Would you please be a little more careful?"

"How big can it be?"

"You missed!"

"[Grabs Sammael by the tongue] Second date, no tongues!"

"Didn't I kill you already? You goddamned monster!"

"I'm fireproof. You're not."

"[Breaking Sammael's lower jaw] OPEN WIDE!"

"Waiting for me, chunk-face?"

"[To Sammael] Listen, Sammy, I'm not a very good shot, but the Samaritan here uses really big bullets. So what do you say we work this out in a nice, peaceful–? [Sammael runs off] Oh, crap."

"[While weightlifting] I hate those comic books. They never get the eyes right."

"You totally just screamed like a boy."

"Heatblast: I got this under control, officers. (Eon's henchmen jump down from the buildings and attack the police) Oh, you gotta be kidding. Okay. Uh, maybe I don't have it under control. (he creates a firewall from the aliens and police) C'mon now; don't be shy."

"Grey Matter: That was awesome!"

"Diamondhead: (sarcastically) Great. Just where I wanted to spend fifth period."

"Heatblast: Dude, what's with all the noise? People are trying to sleep, guy. Couldn't you have waited 'til tomorrow to go on a rampage? Uh, this is the part where you tell me your name, what your evil intentions are, yada yada. You know, you fight me, I fight you; one of us goes home happy. You have done this before, right? Okay, I'll start; I'm Heatblast! (he throws a fireball at Eon) And you were just leaving."

"Diamondhead: Gym class is in session. Today, we play "Pummel the Creepy Alien Dude"."

"Grey Matter: Oh, man! Hiyah! Hmm. Maybe I can work with this."

"I love you Ben Tennyson, and you've never given up on anything in your life!"

"I need you! Grandpa Max needs you! The world needs you!"

"Ben Tennyson, you stupid idiot, Grandpa's in trouble!"

"I'm not afraid of you, you hear me?"

"Guess that got your attention,huh?"

"What about Ben?"

"Don't you touch him you freak! Don't worry Ben, we're going to get you free."

"Ben, are you in there? Ben?!"

"On a scale of 1-10 10 being the stupidest thing you ever done, this is a 15."

"Ben, this is serious."

"Way to go, Ben. You just torched the entire town."

"Don't be a sore loser."

"Famous? For what exactlly?"

"I do know what I'm doing."

"Heatblast. Sorry, cuz, but back at home, you're not a hero; you're just plain old Ben Tennyson. And those aliens you turn into can't help you here. Tootles."

"Not those plumbers. The Plumbers? The secret ones who won aliens? Grandpa used to work for them."

"This place is already dying for me. Rememberance fading. Stolen away. (feels pain, as his body grew weaker)"
