Prolouge

After Chara took over the underground by killing everyone, it's been quiet there and it's become boring for Asriel and Chara. One day, a creature is teleported to the underground, running away from its home. It looks human, but...it's eyes aren't normal and it possesses powers like monsters did...either way, Chara is ready to play kill or be killed with this newcomer.

What's there to expect?

(My oc is the creature and story will change perspectives)
