About this AU
The universe is based around the concept of Sans’ gaster blasters taking him over, changing him into a gaster blaster monster. The AU has a lot of artwork, especially since Sushi did a voice piece on the AU, inspiring various comics and fan stories. The AU can vary between Sans simply having his head change to a Gaster Blaster, to taking on an entire transformation. One of the most popular pieces is a story written by A Bad Time called “The Best of Times, The Worst of Times”, aka BOTWOT.
