'''''Undertale: Last Breath''''' is a FanGame of the 2015 smash hit role-playing game ''{{VideoGame/Undertale}}'', which presents a distinctly different ending to the game's [[KillEmAll Genocide Route]] thanks to the intervention of [[WalkingSpoiler a mysterious man who speaks in hands]] teaming up with an old friend.

* DemBones: The main focus of this FanGame is a battle with Sans and [[DummiedOut Doctor W.D Gaster]], although whether the latter is/was a skeleton is debatable.

* GameFace: Once Gaster's in control, some of his facial features manifest over Sans's face, such as his distinctive cracked head and drooping eyes. When he goes full power, Sans's eyes are replaced with [[OminousVisualGlitch static]] and his teeth disappear.
* GrandTheftMe: A rare ''willing case'' of this trope takes effect when Gaster takes control of Sans's injured body for the final phase of the fight. It eventually backfires when the body tires out, allowing the Fallen Child to get another hit in, destroying Sans entirely.

* BeyondTheImpossible: At the end of Phase 1, [[OneHitPointWonder Sans]] gets hit while offering mercy, causing him to go into a speech asking why the Fallen Child is engaging in the Genocide Route so much, he waits to dust before noticing something that shouldn't be possible for him of all Monsters; his HP wasn't zero from that hit but 0.0001, giving him another chance to end the Fallen Child.

* DemBones: The main focus of this FanGame is a battle with [[ThatOneBoss Sans]] and [[DummiedOut Doctor W.D Gaster]], although whether the latter is/was a skeleton is debatable.
* DownerEnding: [[spoiler:Despite the Fallen Child being defeated and the world saved from destruction, the situation is even '''worse''' than in canon. At least beforehand, the Monsters would all be brought back during the world's resetting/recreation, meaning that if the Player was stopped earlier, many more lives could be saved - even more if they chose to turn away from the path of Genocide to begin with. As is, everyone aside from Alphys' evacuees, Flowey, and Asgore are all dead, and none of them are coming back as the Player's permanent defeat means their SAVE FILE cannot be reloaded anymore.]]

* TakingTheBullet: Each time that you successfully hit Sans before the end of Phase 3, Gaster blocks your slash with one of his hands, reducing the damage you deal to Sans to a survivable level, even for him.

* AntiFrustrationFeatures: Every time you finish a phase, your HP is maxed out and your ITEMs are restored. [[spoiler: [[VictoryByEndurance As you don't get any turns after the first in Phase 3, the latter is essentially useless at that point, though.]]]] In addition, the menu bones in the original Undertale's Sans fight are removed no matter what phase you're on.

* DemBones: The main focus of this FanGame is a battle with Sans and [[DummiedOut Doctor W.D Gaster]], although whether the latter is/was a skeleton is debatable.

* NoSell: At first, when you slash Sans in Phase 3, you deal no damage to him. Only after he exhausts himself do you finally get the chance to finish him off.
* PossessionBurnout: In Phase 3, Gaster seems to be able to fight for an indefinite amount of time once he takes control of Sans's body, but eventually the body tires, and this spells the end of the fight.
* TheFourthWallWillNotProtectYou: During the beginning segment of Phase 3, Gaster destroys all of the options available to the player, which in turn prevents the player from having their turn... [[spoiler:For a short while at least.]]

** [[Spoiler:Also, y'know, the player and Frisk are permanently killed, meaning that any hopes of successfully completing the route are dashed entirely.]]

* BeyondTheImpossible: At the end of Phase 1, [[OneHitPointWonder Sans]] gets hit while offering mercy, causing him to go into a speech asking why the Fallen Child is engaging in the Genocide Route so much, he waits to dust before noticing something that shouldn't be possible for him of all Monsters, his HP wasn't zero from that hit but 0.0001, giving him another chance to end the Fallen Child.
* BittersweetEnding: [[spoiler:The Barrier is broken, Asgore and Flowey made it to the surface, and The Fallen Child is dead, seemingly for good, but everyone else who dies on the Genocide Route didn't live to see the surface. This includes Toriel, Papyrus, Undyne and most unfortunately, Sans. Furthermore, Gaster's fate is left unknown.]]
* DelayingAction: Sans's fight with the Fallen Child, while ultimately hopeless in that the player still wins anyway, gives [[spoiler:Asgore]] enough time to gather his resolve after being informed of everything the player did via [[spoiler:Flowey]], and the two set up an ambush which ultimately kills off the Fallen Child once and for all.

* TheFourthWallWillNotProtectYou: During the beginning segment of Phase 3, Gaster destroys all of the options available to the player, which in turn prevents the player from having their turn... [[spoiler:For a short while at least.]]

* PossessionBurnout: In Phase 3, Gaster seems to be able to fight for an indefinite amount of time once he takes control of Sans's body, but eventually the body tires, and this spells the end of the fight.

* NeutralNoMore: Sans, Gaster and [[spoiler:Asgore]].
