History Characters / Undertale

Tropes applying to monsterkind in general:
* BizarreAlienBiology: Most monsters barely resemble real-world creatures (if at all), are made up almost entirely of magic, and turn to dust when they die.
* NotAlwaysEvil: With a few exceptions like Flowey, Mad Dummy, Muffet, Aaron, and Jerry very few monsters are actively malicious towards the player, only attacking out of self-defense or being driven to kill the player so their soul can be used to destroy the barrier keeping them trapped.
* YourMindMakesItReal: The InUniverse jusitification for the BulletHell attacks all monsters are able to use is that their attacks are manifestations of a monster's thoughts brought into the physical world via magic.

* NotAlwaysEvil: With the exception of Flowey, Mad Dummy, and Muffet, very few monsters are actively malicious towards the player, only attacking out of self-defense or being driven to kill the player so their soul can be used to destroy the barrier keeping them trapped.

* NotAlwaysEvil: With the exception of Flowey and Mad Dummy, very few monsters are actively malicious towards the player, only attacking out of self-defense or being driven to kill the player so their soul can be used to destroy the barrier keeping them trapped.
