Here, have the dialogue of Snow's entire Judgement Hall geno-run battle.
Plus the different attack power levels used.

██████ = Ridiculously Strong Attack
▛▞▞▞▞▞▞▞▞▟ = Justice Attack (Always yellow)
▛▗▘▗▘▗▘▗▘▟ = Normal Attack

* Honey.
* I've got a question for ya.
* Do you think even the worst person can change. . . ?
* That everybody can be a good person, if they just try?
* Hah. . .
* Alright, anomaly.
* Here's a better question.
* Do ya wanna have a bad time?
* 'Cause if you take another step forward. . .
* You are REALLY not going to like what happens next.
* Welp, sorry Tori.
* This is why I don't make promises.
* It's a beautiful day outside.
* Birds are singing, flowers are blooming. . .
* On days like these, kids like you. . .
* Should be freezing in the DEEPEST DEPTHS OF HELL.
██████
* Huh.
* Always wondered why people never use their strongest attack first.
▛▗▘▗▘▗▘▗▘▟
* What, you think I'm just gonna stand there and take it?
* I may be the Judge and the bringer of Justice, but I know that I can't take a hit from that knife.
▛▗▘▗▘▗▘▗▘▟
* Our reports showed a massive anomaly in the timespace continuum.
* Startale's timeline jumping left and right, flickering in and out of existence. . .
▛▗▘▗▘▗▘▗▘▟
* Until suddenly, everything ends.
* Hah. . .
* That's your fault, isn't it anomaly?
▛▗▘▗▘▗▘▗▘▟
* You can't understand how this feels.
* Knowing that soon. . .
* It's all going to be reset.
▛▗▘▗▘▗▘▗▘▟
* Look. We gave up trying to go back a long time ago.
* And getting to the surface doesn't really appeal anymore, either.
▛▗▘▗▘▗▘▗▘▟
* Cause even if we do. . .
* We'll just end up right back here, and most of the others won't even remember.
▛▗▘▗▘▗▘▗▘▟
* To be honest. . .
* It makes it kind of hard to give it my all.
▛▗▘▗▘▗▘▗▘▟
* . . . Or is that just a crappy excuse for me being lazy. . . ?
* Hah. . . I don't even know.
▛▗▘▗▘▗▘▗▘▟
* All that I know is. . .
* Seeing what comes next. . .
* I can't afford to not care anymore.
▛▗▘▗▘▗▘▗▘▟
* Listen, human.
* Frisk, I know that you didn't answer me before, but. . .
▛▗▘▗▘▗▘▗▘▟
* You're somewhere in there. I can feel it.
* Despite everything, you want to do the right thing.
▛▗▘▗▘▗▘▗▘▟
* Frisk, can you hear me?
* Please, if you can, if you're listening. . .
* Just lay down your weapon, and . . .
* Well, my job will be alot easier.
▛▗▘▗▘▗▘▗▘▟
* Welp, it was worth a shot.
* Guess that we're doing things the hard way this time, eh?
▛▗▘▗▘▗▘▗▘▟
* Frisk, I know it sounds strange, but I once thought the anomaly was doing all this cause they were unhappy.
* And when they got what they wanted, they would stop all this.
▛▗▘▗▘▗▘▗▘▟
* And maybe all they needed was. . . I dunno.
* Some good food, some bad puns, some nice friends.
* But that's ridiculous, right?
▛▗▘▗▘▗▘▗▘▟
* Yeah, the anomaly is the type of person who won't EVER be happy.
* They'll keep consuming timelines over and over, won't they, Frisk?
██████
* Now that that's been said. . .
* It's time for me to get Justice for those you've killed.
Her eyelight changes to a solid bright yellow
▛▗▘▗▘▗▘▗▘▟
* Anomaly, you really like swinging that knife around, eh? You know you don't deserve to have it.
* It's not yours, after all.
* It's Chara's.
* She is my best friend, and you killed her.
* I will get Justice for her, anomaly.
Summons one of Chara's attacks, but yellow
▛▞▞▞▞▞▞▞▞▟
* And the locket you wear?
* That belongs to her kind and innocent little brother, Asriel.
* You murdered him without a thought, despite him having done nothing to you.
* He deserves Justice as well.
Summons Galaxia Blazing, also yellow
▛▞▞▞▞▞▞▞▞▟
* Fynn and Undyne...
* You struck them down while they were defending the monsters of Waterfall and Snowdin.
* But they were successful, they stalled you for long enough for all of the others to escape your murderous rampage.
* They deserve Justice.
Uses a magic spear and arrow attack, in yellow
▛▞▞▞▞▞▞▞▞▟
* Quill, the kind, pun-loving guardian of the ruins.
* He loved to bake lemon-key lime pie.
* He never did anything to harm you, all he wanted to do was to protect you, and you killed him.
* He deserves Justice.
Uses a bone and ink attack, yellow
▛▞▞▞▞▞▞▞▞▟
* My beloved little sister. Syrah.
* You stabbed her in the back. She had forgiven you, she TRUSTED you, and you killed her.
* She always saw the best in people, even the worst ones.
* She deserves Justice.
Uses a bone and water attack, yellow
▛▞▞▞▞▞▞▞▞▟
* And you killed so many others... the list goes on and on. I couldn't go through them all if I tried.
* They all deserve Justice.
Uses a massive combination of different magic attacks, yellow, for several turns
▛▞▞▞▞▞▞▞▞▟
▛▞▞▞▞▞▞▞▞▟
▛▞▞▞▞▞▞▞▞▟
* Hey, anomaly.
* Someday. . .
* You gotta learn when to QUIT.
* And that day's TODAY.
▛▗▘▗▘▗▘▗▘▟
* Cause. . . ya know. . .
* All this fighting is really tiring me out.
▛▗▘▗▘▗▘▗▘▟
* And if you keep pushing me. . .
* Then I'll be forced to use my special attack.
▛▗▘▗▘▗▘▗▘▟
* Yup. My special attack. Sound familiar?
▛▗▘▗▘▗▘▗▘▟
* Welp, get ready. Cause after the next move, I'm going to use it.
* So if you don't wanna see it, now would be a good time to die.
* Welp. Are you ready?
* Survive THIS, and I'll show you my special attack!
██████
* Hisss. . . Huff. . .
* All right. That's it.
* It's time for my special attack.
* Are you ready?
* Here goes nothing.
* Yup.
* That's right.
* It's literally nothing.
* And it's not gonna be anything, either.
* Hah. . . Ya get it?
* I know I can't beat ya.
* One of your turns. . .
* You're just gonna kill me.
* So, umm. . .
* I've decided. . .
* It's not going to BE your turn, ever.
* I'm just gonna keep having MY turn until you give up, and reset.
* Even if it means we have to stand here until the end of time.
* Capiche?
* You'll get bored here.
* If you haven't gotten bored already, I mean.
* And then you'll finally quit, or at least I hope you will.
* You're very determined, aren't ya?
* You'll never give up, even if there's absolutely NO benefit to it at all.
* If I can make it clear that there is nothing past this, then maybe you might reset.
* But I already know that, no matter what, you'll just keep going.
* Not out of any desire for good or evil. . .
* But just because you can.
* And because you can. . .
* . . . You feel like you have to.
* But now, anomaly, you've reached the end.
* There is nothing past this.
* So, in my opinion. . .
* The most 'determined' thing you can do here?
* Is to give up.
* And. . . *yawn* do literally anything else.
* Hah, did ya really think you would be able-
* . . .
* . . .
* . . .
* So. . .
* Guess this is it, huh?
* I don't blame you, Frisk.
* It's not your fault.
* But anomaly. . .
* . . .
* Just. . .
* Don't say I didn't warn you.
* Welp.
* I'm going to Muffet's.
* Syrah, do you want anything?

There are two notable separate 'personalities' in the human- there's the Genocide one, the "player," Snow refers to it as the Anomaly, the Pacifist, Frisk, and although the first fallen child, "Chara," is there, they come out rarely, only reliably appearing at the end of a genocide run.
