"Perfect" Timeline

Takes place in yet another newly created (and probably unoriginal) Undertale Universe.

Many years ago, a human child named "Frisk" fell into the underground. Filled with grief due to realizing they survived the fall, filled with anger because of how the other humans treated them, and filled with DETERMINATION, for it was their dominant soul trait, they immediately went genocide. They disregarded everyone's attempted companionship, slaughtering all who got in their way, and forced the rest out of hiding in a desperate attempt for more EXP. When the demon that called itself "Chara" came to Frisk and helped them erase the world, they realized what they had done. Suddenly feeling sorry for the lives they had ruined. And so Frisk reset, bringing everyone and everything back to zero. They became a true pacifist, enjoying every moment, every battle, every line of dialogue their friends had with them. Finally breaking the barrier, with the help of Asriel, and setting the monsters free, Frisk was happy. And they had a choice.
