Happier with him (x chara x reader oneshots and headcannons)

"Chara is the stronger one"

You and frisk were trapped watching Chara and undyne come to finally take down x gaster, you banged on the clear wall trying to get Chara to see you

"Chara! Don't!"

"If you don't want to end up like her, I suggest you leave and give me MY human."

X gaster told undyne as she was holding the heart locket alphys gave to her while smiling, undyne clenched her hand closed and her smile got wider

"YOUR human? Haha..The human is MY student..AND WERE GONNA BEAT THE CRAP OUT OF YOU."

Chara aimed his knifes cutting x gasters body making him smirk at Chara

"I knew I wasn't wrong!"

X gaster thought looking at chara's glowing red eyes

"You are all I need"

Undyne jumped up and smashed his head down to the ground knocking him back cracking his head severely

"The way you show your emotions is so amusing, chara. That's why you have always been my favorite. Frisk doesn't deserve you as a brother"

Chara got angry at what he said and so did undyne

"SHUT THE HELL UP."

"I will give you everything if you give me your determination"

X gaster kept the evil smile on his face using his hands to attack undyne but she blocked them with her spear

"NO ONE NEEDS YOU IN THIS WORLD ANYMORE. YOU WONT CHANGE THE COURSE OF THIS WORLD"

"You are my creation. If you destroy me you'll die too."

"I'm not going to kill you. Your own actions are taking care of it. I'm here to keep you in confinement until you regret what you've done."

Chara stood next to undyne as she kept her spear aiming at x gaster

"We Will take care of this world and you will be forgotten by everyone."

"Your so ridiculous undyne. Your hopes and dreams do not work in my reality"

Her eyes widen seeing alphys and everyone else ready to attack them in a melted form, alphys has a tear going down her face while she was being controlled. She never wanted this to happen

Chara's eyes widen as well, he stood there in shock as undyne yelled

"CHARA! RUN!"

Everything was glitching and then..undyne was gone. Chara was leaning up against the clear wall blood over his clothes, you kept banging on the wall but he couldn't hear you

"Chara!"

Chara still didn't give up, he made his knives appear and destroy the melted "asgore" but it didn't work. He came back and grabbed him back the back of his head bringing him to x gaster

X gaster used his finger to put chara's chin up, putting his hand directly onto his chest. Tears filled your eyes as you watched x gaster take half of his soul

All you could hear was Chara screaming in pain as it happened, there was nothing you could do. Frisk was scared himself as he watched you scream his brothers name

Now Chara shared souls with x gaster, he held Chara who was passed out looking down until he looked at both of you with his red and purple colored eyes.

"CHARA!!!!"
