Dialog Panel No.1, Series/Issue No.1

Dialog Panel #1 is the first Dialog Panel of Series/Issue No.1, as well as of Undertale: ACFPV.

Summary
Dialog Panel #1 explains the events leading up to the AU/AT/etc.’s setting. Flowey, once known as Asriel Dreemurr, has the ability to continually reset the world he lives in, the Underground. Eventually, Flowey becomes tired of being a flower, and wishes to return to being Asriel. He manipulates the Underground’s current Royal Scientist, Dr. Alphys, into beginning an experiment, which involved extracting Determination (A substance discovered by Alphys’ predecessor.) from a fallen human child using the DT Extractor. Flowey would use this oppertunity to absorb the human’s SOUL. Flowey succeeds, until the DT Extractor is activated.

Flowey, having absorbed the human’s SOUL, begins to split into two versions of himself as a result of the DT Extractor, thus resulting in Flowey, the human, and the second version of Flowey all being sent back into time.

Trivia

 * This is the first-ever Dialog Panel of Undertale: ACFPV.
 * Something not mentioned in the Dialog Panel is that Flowey had a conflicting desire to remain a flower, or becoming Asriel, resulting in the split.
 * The Sixth Human could have been the human with a Justice SOUL, although this is uncertain in Undertale’s canon lore.
