Hahaha, this is about you

Chara smirked as Gaster Blasters surrounded her. "Try again, comedian." Chara ran out of way as she protected herself by the green shield.

Beware, beware, the skeptical
Of smiles, their smiles of plated gold

Deceit, so natural
But a wolf in sheep's clothing, is more than a warning

     Chara laughed as her green shield disappeared. She saw bones flying her way as she had her knife in her hand and sliced at some of the bones, dodging I there. She panted. "Tired already kiddo?" Chara growled at Sans. "Shut your mouth, comedian!"

Baa baa black sheep
Have you any soul?

No sir, by the way
What the hell are morals?

Jack be nimble, Jack be quick
Jill's a little white and her alibis are turning tricks

     Chara rolled her eyes as two Gaster Blasters were shot at her. She easily dodged as she destroyed some of the bones with her knife. "Stop trying and let me kill you Comedian!" Chara yelled as she sliced her knife down towards Sans. "Heh.. That won't be happening any time soon kid."

So could you,
Tell me, how you're sleeping easy

How you're only thinking of yourself.
Show me, how you justify

Telling all your lies like second nature

Listen, mark my words one day
You will pay, you will pay

Karma's gonna come collect your debt.

     Chara growled in frustration. "Damn it.. Let me do it for once, then you can be with all your idiotic friends!" Chara yelled out. She attacked Sans again by shooting her knives at him. Chara panted and shook her head. "One attack, and you'll be dead!"

(Wait 6-7 secs)

     Chara panted as she dodged all of his attacks. Soon enough she grew tired as well as Sans she could tell. "Kid, please. You can show mercy, you know? A neutral run. So give up now and give your old pal a hug." Sans said. Chara narrowed her eyes as she let out a dark chuckle and shot her knives at him. "Heh.. Knew you would do that..."

Aware, aware, you stalk your prey,
With criminal mentality

You sink your teeth into the people you depend on
Infecting everyone, you're quite the problem

     Chara continued to let out a dark chuckle as her light blue soul appeared as she shot beams out and grabbed both of Sans's arms. "Give up now." Chara almost said in a whisper. She shot her black covered knives again.

Fee-fi-fo-fum, you better run and hide
I smell the blood of a petty little coward

The megalomaniac smirked as Sans easily dodged the knives and teleported, shooting a Gaster blaster, destroying Chara's light blue knife. The killer growled as she narrowed her eyes. "Hehe.." Chara smirked as she moved forward her purple knife as it shot out purple bullets.

Jack be lethal, Jack be slick,
Jill will leave you lonely dying in a filthy ditch

The bullets went straight towards Sans. "You know Frisk will do a genocide ending. Frisk will do it in their own. You all should know." Chara watched as the bullets reached Sans. "Not quite kid." Chara gave a growl as she saw Sans there with a spinning bone.

So could you
Tell me, how you're sleeping easy

How you're only thinking of yourself
Show me, how you justify

Telling all your lies like second nature

Listen, mark my words one day,
You will pay, you will pay

Karma's gonna come collect your debt

Chara sighed. Bones flew at her as she dodged them, cutting them like she had others. "You don't give in. Even if Frisk can reset, I can reset too." Chara's eyes glowed red slightly as she closed her eyes soon.

Maybe you'll change
Abandon all your wicked way

Make amends and start anew again

Maybe you'll see
All the wrongs you did to me,

And start all over, start all over for me

Chara opened her eyes as the remaining soul colored knives surrounded her as well as her 'hatred' covered knives. "Now die, Sans!"

'Who am I kidding?
Now, let's not get overzealous here

You've always been a huge piece of shit!
If I could kill you, I would,

But it's all frowned upon all in fifty states
Having said that,
Burn in

HELL!'

Chara shot the knives towards Sans, making sure she didn't miss this time. "Give in already! There's no chance that you possibly could win against me!"

So tell me,
How you're sleeping easy

How you're only thinking of yourself
Show me, how you justify

Telling all your lies like a second nature

Listen, mark my words one day,
You will pay, you will pay

Karma's gonna come collect your debt

Karma'a gonna come collect your debt!!

Chara widened her eyes as she saw a Gaster Blaster head above Sans. "Oh really kiddo? Is that so." Chara narrowed her eyes. "You should be the one dying and burning in HELL!"
