Rather than leading to a Game Over, this leads to an ending where Papyrus decapitates Frisk with one swing of his bone, finally returning peace to the Underground. Papyrus agrees to spare Frisk, but a la Sans, backstabs them and kills them in a single hit. The Player taunts Papyrus and constantly fights him before sparing him at the end.From here, three sub-endings can be achieved: With his brother dead, his friends massacred and his chances of reaching his dreams of becoming a Royal Guard member crushed, Papyrus decides to fight Frisk and finally end the madness. The Player has not collected all six or any Combined SOULs.There are six of these and finding them all - they're hidden within the Underground - will unlock two extra battles and a hidden ending.Īnd again speaking of which, there are two endings to the mode:
These are the SOULs of the Six Humans fused with those of several monsters. Speaking of which, the Combined Souls are a new element to the game. Papyrus also serves as the final boss if the Player has not found the Combined Souls. Papyrus's battle is moved up to after Sans and the updated Asgore fight, with his fight taking inspiration from several "Genocide Papyrus" fights and a few incarnations of "Disbelief Papyrus". Mettaton is unique in that he's first fought as Mettaton EX as in the Neutral Route, after which the new Mettaton NEO fight proceeds. Virtually every boss in the game is altered somehow, though Sans and Undyne the Undying have the least changes. Some NPCs the player never fought are now battled, such as Alphys, Grillby (both fights taking inspiration from Alphys NEO and the fanmade Grillby fight, respectively), the Snowdin Shopkeeper and Bratty & Catty (the shopkeepers next to the MTT Resort). Whereas in the original Genocide Route, Undyne the Undying and Sans were the only ones that put up a real fight while all others did nothing and died in one hit, in True Genocide this applies to all bosses. The DLC takes many elements from various fanmade Undertale fights.
