2015 Undertale AU: TURTLENECK

This is an AU that used to be lazily developed with main characters that are supposed to switch roles (excluding Flowey and Temmie). I nearly deleted this when Inverted Fate showed up. Now, I made everything much more different and made many more connections.

The Legend of Humans and Monsters have the same result of Chara and Asriel who both died, but with an aftermath.
Sans and Papyrus are the defenders of the UNDERGROUND, living in the Roughins.
Undyne and Gerson is the cause of the STORY and impacts most of the game.
Flowey is the cause of the GAME to make Frisk fall.
Toriel and Asgore were overthrown due to lost hope and now living in Snowdin, sleeping in the Snowdinn.
Alphys is the cause of Flowey and fixing mistakes as a serious scientist.
ENDING STAYS THE SAME. The only change is dialogue.

Remember:
Flowey is Flowey.
Temmie is Temmie.

Let me know what confuses you as you read. This AU was made before Storyshift and Inverted Fate. I'm sure Underswap and Altertale was released before this one. In my view, I claim this the very first role swap AU since this was 2 months and 14 days after Undertale's release, but possibly, fans may have kept their role swap AU to themselves before this would show up.

"Gerson wants you. Undyne wants to snap your neck."
