You'd fight XGaster for Frisk, you'd do that anytime. If you want your world back, you gotta fight for it. It would all change with this one fight. The world would never be the same, it felt like the entire multiverse was watching, waiting for you to either succeed or fail. 

You stepped into the black void, ready to fight.  

~

Out of you, Frisk, and Chara, you were the stronger one. Chara was incapacitated by a spike to the arm, but you were still there, still alive, still fighting. Your determination was the strongest, and XGaster had chosen you for his experiment. You would be the experiment for the XEvent. XGaster held you up by the scarf Frisk had given you all those years ago, injecting his magic into your soul in exchange for your determination. 

You screamed in pain, to no avail. Your hopes and dreams don't work in this reality.

And yet, half of XGaster's magic was yours. One of your eyes went from e/c (eye color) to purple, matching the color of his magic. 

You were no longer fully yourself, to put it lightly. You now shared some of XGaster's personality, though the latter was now nicer than usual. You dreaded when your dad would call you again, since he would notice your personality change and your purple eye. To say the least, he would be pissed that XGaster would hurt you for his own sick experiments. 

You had to get out, one way or another. When XGaster wasn't looking, you called your dad and asked him to pick you up immediately. He agreed, no questions asked. You were taken to the anti-void, where you fell to the ground immediately, crying. 

"What's wrong?" Error asked. You looked up so he could see your purple eye and drew your soul from your chest. The gold color was almost completely gone and half of it was bright purple. 

~

"We'd have to completely destroy your soul, though I know a good replacement." Error said. He held his hand out to you and you took it. You found yourself in a dimly lit castle. Nightmare talked to a skeleton covered in goop, who agreed to give you half his soul. 

You completely destroyed the half of XGaster's soul, he never deserved it anyways. Your new soul was half of what seemed to be an apple, though upon assimilate if with your human body it turned to half a heart. It was black, but it radiated some sort of dark purple smoke. 

* A new soul resides within you. HP: 100/100

You had an oddly high amount of HP...whatever. At least you have a new soul, you would test out its abilities later. 

You arrived back in the anti-void just in time to see Ink arrive as well. 

A truce was made that day. No more creation, no more destruction. Tensions would grow between the two sides, though there was no "sides" in all actuality. Everyone only did what would benefit themselves, these "sides" being used to group everyone with traits seen as "destructive" as one, same with the "creators". You were now what could be considered a destroyer. 

And that was fine by you, as long as you got Frisk and Chara out of XTale. They had told you earlier that they didn't want to be a part of that universe anymore. 

But by the time you had planned to break them out, it was too late. Only Sans was left, now calling himself Cross. So Frisk was really gone?

Sorry for the delay on this chapter, I got lazy and I've had a lot of schoolwork to do the past new days. Expect another chapter within the next probably 2-5 days, that's all :)
