Shared Goals (Xtale Insert) (Cross Chara x Xtale Reader)

Hello, My Name is Y/N, and I am a surviving victim of OVERWRITE. This is my story but, let's start this story from the beginning. Before I tell you my story, you need to know a few things about me, so you don't get confused. I am from the Au once known as Xtale. I say once because Xtale no longer exists. I was created by X-Gaster, thanks to OVERWRITE, as the "Perfect Experiment" and now I fear that I will become the thing that created me. I don't want to become him. I'm afraid of becoming a Horrible Creature like HIM. C.Chara: You won't become him Y/N, calm down. Y/N: Sorry Chara. Anyways, I was created by him due to the power of OVERWRITE. I have the different abilities of several different Sanses in the Multiverse, such as Classic Sans, Nightmare and Dream Sans, and even Ink and Error Sans. Needless to say, that backfired. With the help of several Sanses, even Nightmare, we finally defeated X-Gaster, something we never thought we would say. Here's how it all Started and how it all Ended. Did I forget to mention that I also have a fabulous Girlfriend. C.Chara: S-Shut Up. Hmph! Y/N: I can't even be mad at that, that was just cute. C.Chara: S-SHUT UP! Y/N: Fine, you're no fun. C.Chara: Oh C'mon Y/N, don't be like that!
