You're a skeleton monster and an older sibling to Sans and Papyrus

You were created in a lab years ago, made by Gaster to help the royal guard and King Asgore escape the underground, but ever since Gaster fell in the core that day you focused on your brothers and a small human named frisk

Frisk was a sweet little girl, always coming to you for situations, you honestly loved having her here, but you knew that she was the one doing the resets along with sans and asgore knowing, so you kept your power hidden Incase frisk turned evil possessed by Chara you had to eliminate her

Anywho, you were simply sleeping in your room, enjoying the silence before hearing frisk speaking to you to wake up, you wake up stretching softly as your bone wings flutter softly before getting dressed and heading downstairs putting your jacket on
