After some debating, I decided to arrange these by speaker, not in chronological order. If you think having them in the order they appear in the game would be better, let me know and I might change it in a future version.

Bart

"The people who started the war are the reason. And unless you fight to get rid of the reason, nothing will ever change. I fight to get rid of the reason."

"See ya, you bald geezer! We'll settle this later! 'Till then, get your head waxed!" -- to Shakhan

"There's no way we can lose! No one will die in vain!"

"Today's my unlucky day. Why does this have to happen now?" -- on the Yggdrasil attack

"Sig! What has Gebler's 'Mr. Puniverse' got to say?"

"Well, if it isn't Dr. Uzuki and his... errh, very big friend." -- to Citan and Rico

"Actually our Yggdrasil II did a good job of shooting down that airplane. It was great!"

"Of course, I'm Bart the immortal, whaddya trying to say...?"

"Cute, kid, REAL cute." -- to Billy

"Citan, so some guy named Krelian took the kid... so who cares?" -- about Emeralda

"I don't like the idea of working for free... but I don't like the idea of turning tail and running from them even more!"

"I've never fouled things up yet, have I?"

"They all look the same. Let's start hitting some buttons."

"What can you do now? How about killing yourself honorably?" -- to Shakhan

"If my father knew I was set up by a jerk like this, he'd turn in his grave." -- on Shakhan

"Hmph... if Billy says it, you listen." -- to Fei

"This is freakin' stupid! How the hell could it all end like this?? What were we all fighting for up to now!?"

Big Joe

"Well, young man, if all in this world was that easy, huh? You know, I can't just let you go see for free!"

"You gotta hear my super muchacho information!"

"There was a deep, deep, reason, deeper than the deepest ocean for doing what I did." -- about stealing Fei's money

"Hey, hombre, you disturbin' our amore time?"

"You came all the way to save me, eh? Well done, well done! Someday you'll brag about saving me! Adios amigos!"

Billy

"We are father and son in blood only! I have nothing to do with that man!"

"Stay out of my life." -- to Jessie

"We Etones are merely fulfilling our divine mission."

"What was it that I believed in... all this time?"

"...Do you guys just have too much free time on your hands?" -- to Seraphita and Tolone

"An honorable person? I certainly don't think you are honorable anymore." -- to Stone

"Salvation by faith is something that everyone should have an equal chance at."

"Rest in peace, agents of evil. May all of you turn to dust."

The Captain

"That's because...
I am!
A man!
Of the sea!"

"Haaaaaaaaaaaaaaaans! I'll welcome the guests! You take care of the rest!"

"Hey, kiddo. You supposed to be some kind of pirate?" -- to Bart

"Oi, he's interrupting our men of the sea talk. That Hans, he's such an unrefined chap."

"Thanks to this beer hall, everyone is too sloshed to worry!"

"Hans! Look alive! Take the helm! We'll show how real men of the sea retreat!"

"Blimey. I think he's got it." -- after Fei does the "Men of the Sea" routine

"A walrus with a penguin for a son! Ghar, har, har!"

"Don't know where it is! Don't have a ship! Don't worry with details! Don't you know that attitude of yours is why that kid won't talk to you?" -- to Hans

Chu-Chu

"Nice chu meet chu! I'm Chu-Chu! I fell in love with you when I first saw you in Bledavik!! Wherever you go, I shall go chu! Oh my! I just declared my love!" -- Chu-Chu introduces herself to Fei

"Munchu munchu! Presents are the way chu a woman's heart! Here's your reward." -- after eating the Spider

"My eyes dry out when pretending chu be a stuffed animal. Ouchu!"

"I'm changing, so don't chu come in."

"If I break something, Fei will comfort me, right? So what should I break?"

"Fei, still sleeping? A maiden's kiss might wake you up. Oh, what am I saying? This is chu embarassing!"

"Uh hmm... Chu-Chu's not a good girl. I'm in that dangerous age right now."

"Kyow! I did it! I did the big big churansformation!"

"Well, let's get ready chu rumble, you bad boy! Get your butt ready chu be kicked across the other end of the horizon!"

"Chu-Chu's maidenly pure heart is only for you! Uh hmmm!" -- to Fei

"I'm exhauschued chu! Since you're here... I'd like a massage!" -- to Fei

Citan

"Oh-oh...!"

"...My, this is a surprise."

"We do not have time to lolly gag around!"

"Fei... no longer wants to watch innocent people lose their homes, their town, those that are important to them."

"Hammer should have been able get that information by now." -- Citan, "In a Daravon Mood"

"Fei, that is the toilet. The exit is that way unless... you cannot hold it?"

"Hmm, the plot thickens."

"Eventually you will be able to unleash its power. Let us hope you use it for the right reasons." -- to Bart, on Andvari

"Do you think you could possibly be a little more subtle? With the amount of activity you have stirred up, you could even wake up the dead." -- to Fei

"It's much easier to be given a place to belong than to make one for yourself."

"Being given one's place frees one from any risks. Misfortunes may be blamed on others."

"Under total surveillance there is no need to bear the price of maintaining one's identity. They simply live under the delusion of being an individual. What could be easier?"

"Resistance is futile. It only makes things painful."

"Humans have the potential. Managers are no longer needed."

"It is rare to be able to talk to a real schizophrenic. But as a scholar, I am extremely intrigued."

Dan

"Let me pray on his weeping face as if it were an idol! Heh, heh... As if I would!"

Dominia

"War, strife, betrayal, deceit are all that are on the Lamb's minds."

"It is our divine duty to rule these crass Earth-dwelling Lambs."

"The ignorant must be led by the wise."

"Are you trying to show us mercy? Or are you just trying to show off...?"

Elly

"Change. How I wanted to change... I've thought of changing, but couldn't."

"What my country's doing... has nothing to do with me."

"If you Gebler are wise, then I'd rather be a fool."

"If Chu-chu saw this, she'd probably faint out of pure happiness." -- on the Chu-chu Tribe room in Shevat

"Why are you so shook up like that?"

"A single hand cannot clap."

"Some things only the weak can feel... but weakness does not make them secure. It's because they are weak, that they can develop kindness... and never look down on people."

"It's all in your mind." -- Elly follows the teachings of the great Chop-Chop Master Onion

"So don't hide the feelings that are in your heart... Don't fear love..." -- to Ramsus

"I'm not a holy woman of any sort. I'm just a reguar woman... I get angry... I cry... I laugh..."

Emeralda

"Kim! Kim! Kim! Kim! Kim! Kim! Kim! Kim! Kim! Kim! Kim! Kim!"

"What do you mean 'resemble'? Kim is Kim?"

"Kim is Kim! Don't you see?"

"Please! Promise me you'll stay, Fei's Kim!?"

Fei

"My father? You mean my dad?"

"...Don't call me son, cuz you sure ain't my pops." -- to Maitreya

"The fight was meaningles. I had no reason... I didn't want to..."

"I hate Gears and I'm not interested in that kinda stuff." -- to Rue

"Fighting and Gears, I hate them both!"

"You're the doc, ...doc!" -- to Citan

"Does the word 'duty' justify all of this?"

"...Hm, you're funny. But don't keep it up or you'll piss me off." -- to Big Joe

"Probably, deep inside I didn't want to help. Somehow, I get the feeling that all I've done I did because I wanted to be needed."

"That's.... not nothing.... ...it's something." [yes, that IS the logical conclusion]

"Let's not imagine things, it's not good for your heart."

"It kinda looks a lot like Bart's gear." [How can something look "kinda" "a lot like" something else?]

"What is this?"
"I have no idea."
-- talking to oneself is the first sign of madness

"A group of facilities formerly created by Solaris." [how can something be "formerly created"? Did somebody different create it now? Were the facilities create it several times?]

"The partially ruined thing self-disintegrated." [Fei: The Dan Quayle of the Xenogears world]

"Just borrowing it... Just borrowing it. Hey, it's not like we're grave robbers or anything! Right? So don't hex us, or haunt us, OK! Please... we're begging you." -- on looting the Chu-Chu shop on Disc 2

The Gazel

"Detestable... Vexing... Cursed..."

"Fade... Vanish.... Disappear..."

"I'd like to your 'instrinsic' power." -- to Ramsus

"Once 'trash', always 'trash.' What more can you expect?" -- on Ramsus

"We are orphans in this universe."

"Every attempt to terminate you has failed. Because of that good for nothing trash..." -- to Fei

"Now, humans! Extol the awakening of god!"

Grahf

"Doth thou desire the power?"

"My fist is the divine breath! Blossom, o fallen seed, and draw upon thy hidden power. Grant unto thee the power of the glorious 'Mother of Destruction!'"

"The absence of wrath is an impediment to you utilizing your true strength." -- to Fei

"It is not worth the effort putting a spineless wretch out of your misery."

"Then all human beings might as well perish! The path to relase us from the eternal cycles of life, the tragedies of history, and the spell of fate!"

"Even if I go to hell, I will live till the end of this world. And if the world does not come to an end... I will destroy it with my own hands!"

"Fei, cut away all the binds on mankind... You should be able to do that now. Save her [Elly] and all the other women with her!"

HAMMER!

"Bro, doesn't it seem like there's something missing here in D Block? Something, or things that you could find elsewhere, but can't find here? Yeah, yeah? Don't you think so, bro? Yeah, what's missing are item shops, oh, and don't forget the weapon shops..."

"It's too expensive elsewhere. Yep. You know, it's gotta be 'Hammer's Ether Bag'!"

"If I become chums with him, I can expand my connections by establishing black market medical treatment routes!" -- Hammer, on D Block's new doctor

"The sound of an opening door! It seems the new doctor was in the next room!"

"One tiny mistake and it's BOOM! BANG! Game Over, man! Get Hammer's drift, bro?"

"Excuse me, doc, but would you mind giving me the safety device? It would fetch a fair price if sold to a collector. Of course, I'd be willing to pay you for it." -- Hammer never misses a sales opportunity

"Yeah! That's my bro! You're too kind man! Much appreciated!"

"The mechanic of champions, me, has had his sins wiped cleans so there is nothing to be suspect of! Ha ha ha!"

"I know it's a bit sudden, but how about buying something?"

"Bro, you did it! You won! You're the Battling Champ! ...or, close enough anyway!"

"I'd like to say 'no problem!' but tomorrow's Finals League is a serious matter. Don't you think you should take care in servicing and customizing your Gear? Our fates depend on it!"

"After all that exercise, the best thing for you is to go beddy-byes!"

"Bro won on his own strength! Stop trying to trump up false accusations!"

"Nah, don't worry about the details. I'm the information man! There's nothing outta my reach."

"Master, sir, did you just see my MAD SKILLZ!? I just might be a genius!"

"I, I know.. everyone thinks of me as some annoying handman who talks too much... I know that..."

"I'm different from you all! I'm not special like you! A 'normal' guy like me has no choice but to do this!"

"For a bit player... like me... this is... probably... the end... I deserve." [NO IT'S NOT!]

Hans

"The Captain is a bit strange. You'll see when you meet him. That's not to say he's a bad old blighter."

"And that big gun is nothing but a useless piece of junk you tacked onto the Thames in a drunken stupor!" -- to the Captain

"Since our work with the 'Ethos' has deepsixed we've lost our 'porpoise'!"

Id

"That was pretty interesting. But dropping a warship on me is cheating... take it back!"

"You will do fine, as my toy... for today."

"Fei is a tenant in the room of cowardice..."

"Dammit... It makes my skin crawl just being in the same body with him." -- on Fei

Jessie

"Stay out of your life? Do you know much trouble your little butt is in?" -- to Billy

"Hey Billy! How long you plannin' on being like that? Get a hold of yourself!"

"What are you getting flustered about, boy?"

"Heh, your brain still isn't working right." -- to Stone

"...But I want you to know that you're not going to be seeing Racquel when you die. That's because your destination is going to be hell!" -- to Stone

"That mob just goes from bad to worse." -- on the Ethos

"Guns don't kill people. People kill people."

"Damn it...! I'm gonna mess you up!" -- to Achtzehn

Johnny

"If you say 'dungeons', I say 'traveling merchants!' You say 'traveling merchant'... and I say 'Shopkeeper Johnny'!"

Kelvena

"Overprotection only stunts the will to be independent."

"Live by one's own strength, stands on one's own feet. It's sad but true that the weak will be weeded out!"

Kim

"Rushing in to fight as if there were only so many 'reserved seats' to the right of life... starting a war is stupid. Inciting it is also stupid."

Krelian

"What may be an eternity to man is a moment for god. I have no need for hesitation."

"You are irritating. Do you wish to cease your existance?" -- to the Gazel

"I try to lead the people 'in my own way.'"

"You're a bunch of stupid fools. It's as if you're all clowns..."

"If god doesn't exist in our world, then... I will create god with my own hands!"

"I will destroy such pretenses of love, for you..."

"Man cannot associate with others without having first deceived themselves. That is the way they were created."

"The time when all things started... The place where all things were one... I am going to return there!"

Maison

"Lately there are far too many barbaria... I mean... highly energetic lads, around the young master."

"You wretched rebel, Shakhan! Make one move and this gatling gun shall be spitting fire!"

"Reinforcements have arrived, young master. Come aboard."

Maitreya

"He might even be more gung-ho than the young master." -- on Fei

Margie

"Bart! You miss the deeper meaning and beauty!"

"The inside of the Yggdrasil smells like a men's locker room. I can't stand it anymore."

Maria

"My father's voice, his smiles... are leaving me."

"...I swore I'd never forget..."

"There's no... no end... to war and resentment."

"I'm coming, Solaris! Siebzehn and I are the dark wings which shall carry you all to your deaths!!"

"The bonds between my father and I... can't be broken!"

Miang

"Hyuga, have you lived down here so long that your mind has slipped?" -- to Citan

"Goodbye... boys."

"It's my job to be hated."

"Calm down, Commander! It's not good for you!" -- to Ramsus

"I am Miang. The keeper of time. The representative of our god -Deus-."

"My, aren't we powerful..."

"Don't you want to become... the ultimate being?"

Nikolai

"I will show the greatness of a perfect life form! Achtzehn, the combination of human wisdom and the strength of steel."

"Species name, dotesque Chu-Chupolin (intellect, astronomically low."

"Die, you pathetic animal! Die!" -- to Chu-Chu

"This huge, powerful, forever shining body. There'll be no aging and death. I was reborn as a new breed."

"Maria... I will always be with you. Now and forever..."

Primera

"..."

"Pa...pa..."

Ramsus

"Shut up! I've got to kill him with my own hands! And all of you in my way are 'enemies'! Enemies, enemies!! Enemies!!" -- on Fei

"Fei, Fei, Fei... Fei this, Fei that..."

"Fei...! In what way is he more superior than I? I will not accept it. I will not!"

"Then from tonight on you will be crying with this woman's dead body in your arms!"

"Ultimately, only I can help myself! I am the only one that can correct this!"

"Fei... If only you hadn't have been born..."

Renk

"Sorry, I'm gonna have to kick his butt. Any objections?"

Rico

"Kid... I mean, Fei."

"Worry about yourself before others! Don't hold back now! Give me your best fight!"

"Defeat is defeat... My wound is no excuse. The Battling champion is... you!"

"Well... I'll be seein' you around sometime." -- Rico, 2 seconds after being arrested ^_^

"Hmph, don't make me laugh. Who gaves about a damn about this crap town... ...I'm crap, too."

"I don't need a reason to beat the crap out of anyone who pisses me off. And of course that goes for you too." -- to Fei

"You ought to be happy, Chu-chu. You have so many friends." -- on the Chu-chu Tribe room in Shevat

"Hmph, so ancient people worshipped meaningless things too, huh?"

"Get outta my head!" -- to the Anima Relic

Roni

"Pessimistic as usual, Lacan... and now you're lying."

Seraphita

"I don't like dark places!"

"When people do you a kindness, you should thank them! That's what grandma always said!"

"Inverted pull-ups are really tough!!! But, I can do 300 pull-ups you know."
-- Sera says this for NO reason during the Ft. Jasper scenes

"You're so ni~ce and ki~nd!"

Shakhan

"Thanks for the laughs. I almost hate to have to shoot you."

Sigurd

"Yes, he actaully calculated this attack... or so he says!" -- on Bart

"Trust him... yeah, I trust he'll get us into trouble." -- on Bart

"Young master, this could be come unexpectedly complicated..."

"This... is not good."

"That is that, and this is this." [o-kaaay...]

"We running out of time!"

"If you can't even save your friends, then how could you save the world?"

Stone

"Billy, my son, don't waste their good intentions."

"So you want to know? But can you bear the full weight of the truth?"

"Billy, there are some things in this world you're happier not knowing. Even lies and deceptions can become the truth for some people of the Earth."

"That's not worth wasting my breath answering."

"I'll be taking that nanomachine factory with me, thank you..."

"I can't be bothered by insignificant wretches like you."

"Just consider it my 'reward in life'. Of course, that includes watching your agonizing death."

"I could succumb to the desire to slice up your body here and now, and drag out your innards... But I can't do that now. I have a matter to attend to elsewhere."

"Ha, confess to me! Pay for your sins!"

"What is the problem with eliminating those people not fit for 'salvation'?"

"A wretched son for a wretched father!" -- on Billy

Taura

"Hey! Quit staring at the naked girl and come over here!"

"There are some things you just can't explain with the word... fate. You're just going to have to see it with your own eyes."

Tolone

"Oh, Sera, don't tell them that... Just as I was building things up to make us sound psychologically superior to them. Damn!"

"Well, that's how it is, folks... it'd help us if you could hurry up and lose."

('Positronic photon brain'... That's bound to get us into trouble with the makers of 'Star Trech'!)

Vance

"I don't care! I'm already messed up as it is!" -- on using Drive

"We don't care much for rank.. and we don't care much for Renk either!"

"I hate hysterical women."

Vanderkaum

"Quiet down, aviation officer! Thanks for your valuable opinion but I am in charge, not you!"

Verlaine

"God? Where does such a being exist?"

"The Ethos used the two sweet fruits of 'faith' and 'technology' well to skillfully manipulate global affairs."

"It was a well-thought out plan. But the managers were extremely poor." -- on the Ethos

"These intentionally perpetuated wars caused much phychological discord." [Sam, is "phychological" a real word?]

Wiseman

"You appear to be looking forward, but in reality you're only looking downward. You're only looking at yourself. Like that, you will find nothing."

"Never underestimate the situation. You might lose badly if you think you can just win by getting a grasp of the concept."

"The floating land which hides behind a wall, as if to conceal their failure. That is Shevat."

Zephyr

"You intend to lose even before you begin to fight...? Against the very people who made you suffer?"

"This child, since her youth has been destined with no choice but to fight." -- on Maria

-- Some guy at the Tournament

-- Guy in Shevat

"Looooong ago, the Chu-chu tribe had a great big guardian god, who could step over huge mountains in one step. The Wondrous Mambo god, yes he was. The Chu-chu Tribe and the Wondrous Mambo god lived happily together in perfect harmony, yes we did. A dreamy sweet existence. But one day, a huuuge red fireball rained down from the sky, and blew away our guardian god as he was asleep. Blam, kablam, bloom! But don't worry! The great big guardian god became a star in the sky! He protects the Chu-chu Tribe, yes he does! Yes, yes, it's a great story... No matter how many times I listed to it, I'm so moved... yes, I do..."
-- the legend of the Chu-chu Tribe, as told by a Chu-chu in Shevat

"War is like that. It abolishes good and bad."

Fruit that's kinda large
Kind hard to say
Why it's so bizarre
Get your Bizfruit now." [Burma-Shave!]
-- Bledavik fruit vendor
