Monsters are a very diverse race in Undertale. They dwell in the Underground beneath Mount Ebott, while humans live on the surface beyond the Barrier.
Besides the protagonist, the fallen human and Flowey, most characters encountered in the game are monsters. The game mentions a few real-world animals, such as mice, spiders, and dogs. It is unknown whether those count as monsters.
Overview[]
King Asgore Dreemurr rules all monsters in the Underground. After The War of Humans and Monsters, the humans from the Surface trapped the monsters underground. Despite the negative implication of the word "monsters," monsters in Undertale are not an evil species. It is even said that monster SOULs are made of love, hope, and compassion.[1]
Monsters are far weaker than humans, both in physical combat and regarding the strength of their SOUL.[2][3] This inadequacy is because monsters are mostly made of magic, which in turn makes them attuned to their SOUL. The damage a monster receives from an attacker is dependent on both the monster's will to fight and the attacker's will to hurt.[4] Monsters, however, can obtain an "unfathomable" amount of power when they absorb the SOUL of a human.
Physiology[]
Monsters come in numerous shapes and sizes. Most monsters physically appear as anthropomorphic, non-human beings (animals, natural/artificial objects, supernatural beings, etc.), with the most notable species of monsters including skeletons like Sans and Papyrus, ghosts like Napstablook and Mad Dummy and Boss Monsters like Toriel and Asgore. Monsters SOULs are upside down and wholly white.
A monster's body is mostly made of magic and is attuned to its SOUL. When a monster gets old, they enter a state referred to as having "fallen down." A monster in this state lies immobile and dies shortly afterward.[5] When a monster dies, their body turns into dust. This dust is often spread onto the owner's favorite thing in funerals so that their essence lives on in their possessions.[6] Monsters' bodies and SOULs are closely linked; when a monster dies, their SOUL is lost forever. Boss Monsters are an exception, as their SOULs exist outside their bodies for a few moments before shattering.
Because of their magical nature, monsters' bodies cannot handle high concentrations of determination. When monsters are injected with it, their bodies liquefy and melt together.[7] The Amalgamates are a clear example of this.
Trivia[]
- Monsters turning into dust when they die likely references to certain battle texts that explain what happened to an enemy when they are defeated in EarthBound Beginnings and EarthBound. When an undead enemy is defeated, the battle text explains that the enemy "turned to dust" or "returned to the dust of the earth."
- It is presumed that at least 322 monsters inhabit the Underground – given the number of monster souls visibly emanating from Asriel Dreemurr as the barrier is broken, plus incorporeal ghosts, who do not participate in the event. Although, it can be contested with the fact that the capital is said to be crowded,[8][9] the capital looking like it can accommodate more than 322 monsters. At least 104 monsters must be killed as part of fulfilling the requirements of the Genocide Route.
- Boss Monsters are very likely the only kind of monster that can live eternally. Using Asgore as an example, he fought in the war between humans and monsters[citation needed] and still lives many years later, existing when the first human fell and when the protagonist fell as well. An explanation for this can be found in one of Gerson's dialogues during the epilogue; Boss Monsters stop aging if their offspring dies.[10]

But the absolute nature of "SOUL" is unknown.
After all, humans have proven their SOULs don't need these things to exist. - Book 6 (from the left) in Snowdin Library - ↑ Humans are unbelievably strong. It would take the SOUL of nearly every monster...
... just to equal the power of a single human SOUL. - Ancient glyphs in Waterfall - ↑ While monsters are mostly made of magic, human beings are mostly made of water.
Humans, with their physical forms, are far stronger than us. - History Book in Snowdin Library - ↑ Because they are made of magic, monsters' bodies are attuned to their SOUL.
If a monster doesn't want to fight, its defenses will weaken.
And the crueller the intentions of our enemies, the more their attacks will hurt us.
Therefore, if a being with a powerful SOUL struck with the desire to kill...
Um, let's end the chapter here... - Book in Snowdin Library - ↑ ASGORE asked everyone outside the city for monsters that had "fallen down."
Their bodies came in today.
They're still comatose... And soon, they'll all turn into dust.
But what happens if I inject "determination" into them?
If their SOULS persist after they perish, then...
Freedom might be closer than we all thought. - Entry Number 6, True Lab - ↑ Monster funerals, technically speaking, are cool as heck.
When monsters get old and kick the bucket, they turn into dust.
At funerals, we take that dust and spread it on that person's favorite thing.
Then their essence will live on in that thing... - School report in the Snowdin Library - ↑ You see, unlike humans', monsters' bodies don't have enough...
Physical matter to take those concentrations of "determination."
Their bodies started to melt, and lost what physicality they had.
Pretty soon, all of the test subjects had melted together into...
Those. - Alphys - ↑ The capital's getting pretty crowded, so I've heard they're going to start moving here. - Punk Hamster
- ↑ It's nice to have a rainy spot away from civilization...
Though, with the city filling up, who knows how long that'll last. - Undyne - ↑ Oh. Right. ASGORE.
He's a real interesting type of monster. The strongest type of all.
We call 'em Boss Monsters.
When they have an offspring, the SOUL power of the parents flows into the child...
Causing the child to grow as the parents age.
But ASGORE doesn't have a child. So he's been stuck at the same age... And probably will be forever.
Huh? What if the child is a human...? What?
Nah. That wouldn't work. So if ASGORE's your father, he'll definitely outlive you. - Gerson, during the Epilogue
