    Y/N is an Ultima but she is also a soul mix. A soul mix is when two soul types combine and become one being. She is a mix of CHAOS and CORRUPTION. The strongest soul types other than Determination and Fear. Y/N was used as a weapon in a war. The Children's war to be exact. She has become emotionally drained since then. She hopes that the bitties will help her become more emotionally active. And they do...

    π€π§π¨π­π‘πžπ« 𝐝𝐚𝐲, 𝐚𝐧𝐨𝐭𝐑𝐞𝐫 𝐫𝐞𝐬𝐞𝐭. Sans, a lazy short skeleton is a victim, along with the entirety of his home and family to a human named Frisk and their friend Chara. After the thousands of times that Frisk has murdered the entire Underground, Sans didn't even know why he kept fighting. It was like he was some type of mindless NPC. However, one day was different. Even in the slightest change, Sans found an opportunity to strike, and finally kill Frisk. However, that was all false hope. Frisk was transported to another world, meeting someone who looked oddly similar to Sans, however, he had a dark shape to him, and black goo surrounded his body. He easily overpowered them, yet, he offered something. That's when Frisk knew, this was the start of an entirely new story. A new timeline. οΌοΌ©ο½Žο½“ο½ο½‰ο½’ο½ο½”ο½‰ο½ο½Žο½“οΌ α΄œΙ΄α΄…α΄‡Κ€α΄ α΄‡Κ€κœ±α΄‡ ᴄᴏᴍʙᴀᴛ Ι’α΄α΄…κœ± (α΄ŠΚœα΄€Ι΄α΄’α΄α΄œ) ʜᴏᴑ ᴛᴏ ɒʀᴇᴇᴛ α΄€ ɴᴇᴑ α΄˜α΄€ΚŸ (α΄œΙ΄α΄…α΄‡Κ€α΄›α΄€ΚŸα΄‡ ᴄᴏᴍΙͺα΄„) α΄€ Κ™Ιͺα΄› ᴏꜰ Ιͺα΄„ΚœΙͺα΄‹α΄€ -2est οΌ‘ο½ƒο½ˆο½‰ο½…ο½–ο½…ο½ο½…ο½Žο½”ο½“οΌ ɴᴏɴᴇ α΄Šα΄œκœ±α΄› ʏᴇᴛ! οΌοΌ¬ο½…ο½Žο½‡ο½”ο½ˆ οΌ₯ο½˜ο½ο½…ο½ƒο½”ο½ο½Žο½ƒο½™οΌ α΄„Κœα΄€α΄˜α΄›α΄‡Κ€κœ± ΚŸα΄‡Ι΄Ι’α΄›Κœ: 1.8-2.8α΄‹ α΄‘α΄Κ€α΄…κœ± κœ±α΄›α΄Κ€Κ ΚŸα΄‡Ι΄Ι’α΄›Κœ: 15~20 α΄„Κœα΄€α΄˜α΄›α΄‡Κ€κœ± "𝑻𝒉𝒂𝒕'𝒔 𝒂𝒍𝒍, 𝒏𝒆𝒓𝒅 𝒐𝒖𝒕 𝒃𝒓𝒂𝒉!" - 𝑭𝒓𝒆𝒔𝒉 P.S: THIS STORY IS IN OWNERSHIP OF @ThatWriterBoi, I AM JUST POSTING THIS ALONG WITH HIM SO IT COULD GET MORE RECOGNITION!

After a few years Sans had grown up and had left the lab taking Erin with him, he had other gaster blasters but preferred his only female blaster. They confined everything with one another but when frisk comes into the picture, things get really awkward for Erin as she might just be given away by the little brown haired rascal. She may even have possible powers only Dr Gaster knew

    Have you ever wondered that out of the thousands of humans during the human and monster war that not even one sympathized with the monsters? I bet you do, for I certainly have. But perhaps you haven't heard of the story of The Lady in Green. There are many others before her who helped the monsters but her story is the most tragic and well known. And who am I to know such a story that even you don't? Well that's something for me to know and for you to find out. Preview: "Crunch Crunch. Snap!" Kimora wakes up with a start, eyes blinking slowly as she sees gray paws. Slowly she starts to look up, breath catching in her throat as she starts to recognize what she was seeing. A bipedal monster covered from head to toe with flint gray fur with tall cat-like ears accompanied by a long slender tail, orange eyes with a face of a mountain lion, with sharp thin fangs that protrude out of its top lip as it starts to open its maw. It was at that moment that Kimora remembered the scary bedtime stories her mother used to tell her when she was a child. That if you were a bad kid the monsters from the forest would come over the village in the middle of the night and drag you into the woods. And no matter how much you screamed, no matter how much you struggled, the monster's magic made it so that no one could hear you. And then when the monster goes past the village's borders they would devour the naughty children alive. Suddenly she felt like a kid again as she could hear her heart thundering loudly in her ears as she sat frozen on the ground. Midnight claws flash in front of her face, ones that can easily tear through flesh. The monster has come for the naughty child. And that child was me.
