"It's a Beautiful Day Outside... by Septiplyierfangirl

......"It's a beautiful night today. The stars are twinkling, the crickets are chirping...On nights like these, villains like you, should be burning in hell"...... It was a simple, ordinary day. Just another reset. Telling joke and puns, making puzzles with Papyrus, forced grins, hourly naps, breaks from his multitude of jobs... Everything was as it should be. Then he was back at Snowdin, taking a regular stroll with Papyrus and his dad. "Sans! Look out!" Sans turned around as a wormhole-thing opened up. The vortex winds had already lifted him off the ground, slowly pulling him toward the hole. "Sans!" "Papyrus, help me!" ...."Hello? Hey man, are you okay?"....

Timelines (A Doctor Who/Undertale crossover) by introverted-actress

What happens when a human gets tired of resets? When the thrill of a genocide route becomes boring and mundane? This is exactly what happens to Frisk. They spent so much time going through reset after reset that now they are growing tired of it. However, little do they know that their next timeline will be one of the most interesting they've ever had. When Frisk resets after an incomplete genocide, it captures the attention of a certain alien Timelord called The Doctor. He has to travel between dimensions to investigate this strange anomaly, but ends up with an adventure much more strange than he had initially anticipated. This timeline is breaking. The entire reality is being torn apart and it's up to Frisk, Sans, and The Doctor to stop it. (Disclaimer: I do not own Doctor Who or Undertale. The only thing I own is the plot line and the writing.) Cover art by @GodOfChaos3900
