"Don't you even think about it!" Ran again, after telling George about his...design flaw
"You wouldn't dare..." Ran yet again, right after the above
"God! How can you be so nonchalant in the middle of battle?! I mean, I can understand if you're stupid, but this kind of random behavior is completely uncalled for! Why in the world would you want to behave so absolutely idiotically?! Aw crap..." Ring Man
"I will not die like this... I will not be squashed like a fucking bug by a goddamn space rock! I WILL NOT!" Bob, he gets better though
"Okay, here's what we're going to—" Nate (Attack of X arc)
"Uh...That's not good, is it?" Wind Man
"Woo! Who would'a thought I'd be the one to survive, eh?" Blizzard Man, shortly before being crushed by Gamma
"Hey! What're you doing?! Let me go!" Random
"George, what the hell do you think you're doing? I just kicked you out of—" Double
Stay back, Lord Siegfried! I am a great sorceress, and you'll never take me alive! Croona Travoria
"We are the advanced senior mages, taught by Miranda Deegan herself! We can stop this lunatic and save the school... or we can cower like helpless kittens..." Selton Nallick, advanced student at Quiral School of the Arcane Arts
"The only help you're getting from me is... an ass... kicking... fag..." Brett Taggerty, seconds before his explosive demise
"I'm... sorry if I w-was rash, earlier... farewell, Dominic Deegan... I... hope you... you do not... forget me..." Lord Siegfried
"Do not think about trying to save me. We had less than five minutes to save you. It took four. You were saved by the love of those around you... love that you forged out of loyalty and compassion. And... you were saved by my love... for you... one whom I... would call... my brother. Klo Tark
"I choose to see you die by my sword, Demon! We-" Kau'shala Val'Sharen, just before being snapped in half by his own demon-possessed dragon.
"It is not so hard after all..." Diva'ratrika in The Longest Wait
"This is a nightmare! Look! The streets are empty! Everybody is gone. It has to be a nightmare!" Yunir Sarghress, just before the warden Chirinide's "mercy killing" of him.
"Don't... touch... me!" Ven'nedia Vloz'ress' warning to Kiel'ndia Vel'Vloz'ress as she was being petrified by her own adopted daughter.
"I'm... n-no-t..." Yaeminira/Vy'Chriel, trying to deny she is a Nidraa'chal
"Heh, that's funny. I'm not even afraid to die anymore. Yes. Go ahead, Mother. Do what you do best. Do the only thing you know." (last thoughts) Syphile Val'Sarghress during her Dying Moment of Awesome, shortly before Quain'tana kills her
"Greetings Ky'ovarde. Are you interested in learning a few secrets? Without my help, you have no chance of winning this war." Sene'kha Vel'Vloz'ress, trying to tempt the Kyorl carrying out her execution
"I'm sorry. Farewell... my... friend." Naal'suul Val'Beldrobbaen as her seed takes over. Though some of her may still be in there...
"Why did you betray us all!? We were your family! Your own blood!! Too many have died because of you!" Kyne Val'Sharen calling Sarv'swati out for her betrayal, and preparing an attempt at Taking You with Me.
Toren's last words before Ian drops a bridge — no, make that a hotel — on him are the not terribly memorable "URRK!!", but he does get off quite a Sedgwick Speech in the combat leading up to that.
"Taking out the feeble, old human woman isn't quite as easy as you expected, eh? And the effects of that device you used shouldn't last for too much longer, either." Anita, to Sarine, who has just used an anti-magic grenade on her. Sarine answers, "It'll last for long enough," and it does.
"Let 'em go, you bitchy little overpowered sad sack!" Ellis, who isn't exactly "killed," but rather "dispelled" by Ian
"I only wanted to help..." Ian
"While I might not be quite as adept in combat as Anita is ... please do give me some credit." Paul (followed by a sigh as Jon draws a bead on him)
"HAH! Oh, I am going to miss you, bitch!" Sarna, to Sarine in their fight (numerous inarticulate grunts and screams follow)
"Ugh! It-it's happening a lot faster now...I th-think...I..." Alistair, before turning into a bird
"My family..." Martin
"I had no choice...it wasn't my fault. Young...that monster! He forced me to devise the plan... Jeanne...she was...all alone. Waiting...when she died. And I did nothing. My children...my children..." Diego

"Please." The robot from Chapter 33
"Emma...will you take my name?" Edward Jones
"Hullo, Renard. I'm just doing the evening survey. Need anythin'?" Daniel R. Schiff
"Oh, man, there goes my chances of making the Top 40 on the rap charts..." Auto
"...well...crap..." Pharaoh Man
"You feel it, too... don't you... brother...? This... surge of power... far exceeding my own... heh... looks like I might know why Dr. Light chose to... do this after all... That girl you serve... the one who talks to Angels... she'll never be safe. You... know this, right?" Mega Man X
"You! How DARE you pull the yaoi card! I,Napalm Man, shall knock you down for the injustice you have inflicted upon me on this day! ...you look kinda differenct from the last time I saw you. AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH!" Napalm Man
"I INVITE YOU TO TRY, MAGGOTS! ...oh, bugger." Dr. Dominic Doppler
"Takes a bitchin' long time to recharge, though. And it runs out in like two hours." A guard at the American embassy in Tknsydska, discussing his mp5 player with his partner shortly before being sniped
"HOLY CHRIST!" The aforementioned guard's partner, shortly before being sniped
"What the—" A third guard, confused by Ocelot dancing around

"Don't try to lie to me with your lies! I know you did it!" A third Shadow Moses guard versus Nano Jackal
"The spirit of the warrior will always be with you. Don't be sad... we'll meet again someday." The Sorrow. Slightly subverted, as he immediately comes back as a ghost.

"What th-" Some Mook killed by Liquid in a Sorrow-induced flashback

"Screw that, I'm staying right here until—" A North African mook, sniped
"Yaaaagh! Come and get me you bastards!" A North African mook, killed by Raven
"Who's the dumbass now, suckers? You are, 'cause you're all dead! Suck on that!" A North African mook, killed by Vamp

Ocelot: "Fine. I'll accidentally set the current to high. But this isn't going to be quick." "Figures." The DARPA chief

"In fact, the only thing I do care about is that Ocelot suffers horribly." Psycho Mantis. Not his actual last words, but his last words on-panel before his death.
"Well, I guess I do owe you one." Cyborg Ninja. Not his actual last words, but his last words on-panel before his death.
"I'm going to go swat down a couple of bothersome flies." (thinks: "It's happening. It's happening. It's finally happening.") Liquid. Not his actual last words, but his last words on-panel as a living man.
"Rule, it's like this bunny. Who do you think this rabbit is to someone! EVERYONE!! But who do you think this rabbit is to anyone!! HE IS NO ONE! I... don't... know him... but I can... still respect... his existence!!" Meander (translated from his garbled speech). This is actually a subversion, as he doesn't die... well, not physically. Mentally, he is completely destroyed.
"DON'T SHAKE HIM, YOU IDIOT!!" Rule. He does have a long monologue in his dying moments, but it's mental.
"G-Go—D-Die!!" TY, moments before SV punches him with enough force to send him flying across the room and crashing into a wall.

"Nooo!!! I...! I didn't want this! I don't want to be a part of this network! Venom 8! What did you do to me! I lived alone in the dark. I was content there! What did you do!!" Antrodiaetus unicolor. This arc has a high death toll.
"Just don't look! Everything will be fine, JUST DON'T LOO-" Bubbles
"I believe you." Courage
"...We're not gonna die, are we?" Zim
"I'll be honest, Irken, I can't tell you what WILL happen. Only what might. While it is my truimph, I simply cannot tell you that this is...the future..." Dr X, just before his own bomb consumes him and all of reality.
"Too...late...Too...late...Too...late..." The Cluster mook, mocking Monkey that he has failed to save existence.
"This won't rid you of me! You know that, right? Erased memories always come back! I'll grow right back! Dorothy is mine forev—" Head Alien I, a third friggin' time, his consciousness having accidentally been siphoned into Dorothy's mind instead of Head Alien II.
