The wise skeleton knows a lot about this world and can use telepathy to talk. The invisible figure made his way to Snowdin and met Sans, the skeleton. Suddenly, it disappeared and the Human Child lost conscious. The creatures tried to communicate with the figure, but there was no reaction. They saw a mysterious figure standing out there – it looked weak and broken.
One day, monsters of the Underworld found a strange door and entered it. The routes of violence and genocide started and ended for ages. However, there was someone watching from far away. This nightmare made the creatures of Underworld shocked. Frisk start killing everyone he meets on his way, trying to dominate the reality and get the victory over the mightiest monsters. However, when they see the barbarian behavior of the Child, demons start wondering, who are the real monster here. The history of this timeline starts when the Human Child climbs on the Ebott mountain and then falls down, rolling right into the depth of the Underworld, where the demons live for ages. The support of Gaster brings health and stamina of the skeleton. Last Breath is an alternative timeline of the Undertale game, where Gaster helps Sans in the main battle of the game.
