The **Lost Souls** are enemies fought during the battle against Asriel Dreemurr. They are the souls of the protagonist's friends who have to be saved to progress with the battle. Their fight is done in a boss rush fashion, where the player has to fight all the major characters in a similar way to their respective boss fights.

## Attacks

* **Undyne:**
	+ The Lost Soul throws arrows at the protagonist from all sides in Green Mode and they must shield themselves from incoming spears.
* **Alphys:**
	+ Small rectangular Mettatons glide down on umbrellas while tossing hearts embroidered with the letter M as they reach the bottom of the screen.
	+ Bombs marked with a plus sign move downwards, which explode into lasers of a similar formation when shot with the yellow soul.
* **Papyrus and Sans:**
	+ The Lost Souls attack the protagonist with a series of bones scrolling across the bullet box, which can be dodged by jumping. Blue colored bones are used, but rarely.
* **Toriel and Asgore:**
	+ The Lost Souls move their hands along the sides of the screen and leave behind large fireballs that move towards the protagonist's soul after a moment.
	+ Partial circles of fireballs gradually spiral in from around the bullet box.

## Strategy

* To defeat a lost soul, one must ACT three times until their memories flood back.
* For Lost Souls that come in pairs, one must ACT four times in total. If all four ACTs are used on the same Lost Soul, then the other Lost Soul's memories will flood back immediately after the first one. Otherwise, both will regain their memories simultaneously.

## Trivia

* Unlike the other Lost Souls's dialogue, Sans's dialogue sways. This movement is not the same seen when characters are afraid; that motion is akin to trembling.
	+ He shares this with Napstablook, whose dialogue sways during the fight with them.
* Sans, unlike Papyrus, doesn't use the Comic Sans MS font or his unique sound bite before being saved.
* Attacking Undyne's SOUL will cause "MISS" to show up several times instead of once.
* Using the Butterscotch pie while fighting Asgore and Toriel will make them remember the smell, requiring the protagonist to ACT only one more time to help them recollect their memories.
* This is the only instance in the game where the protagonist battles Alphys.
