The Kumuzilla is a massive Pink Creature fusion made of presumably all of the creatures in the city that made its debut in Game Over Part 2.


It is a massive pink blob, which has countless Human Souls stored inside of it.


Kumuzilla technically doesn't have a personality due to lack of a soul, and/or a brain perhaps. However, it is controlled by Bete and used to kill and collect souls. It is perfectly fine with killing people with no remorse and is attracted to human souls, which allows it to hunt down other humans.


  • Normal Pink Creature abilities.
  • Supernatural Strength: The creature has incredible strength and is strong enough to take down a building with a swing.
  • Diffusion: The creature is made up of hundreds of smaller creatures to where if hurt, small ones will fall off and kill any nearby threat.
  • Magic Sense: The creature can see human and monster souls through buildings. This is similar to Zachary's ability.
  • Expansion: In the fail timeline we learn that Kumuzilla can expand its body to break free from the barrier the Rave made.


Game Over Part 2

Kumuzilla was first mentioned by Zachary, in his warning towards Undyne and Ronan. It caused the ground to tremble, and emerged soon after began attacking Gaster and Jessica. Kumuzilla was shot by three Perseverance Officers, but it was counter-productive and created components of the creature, which then killed the three officers. It also sent three of its components to steal Ronan's Soul. Two components were shot by Ronan, and the other one sneaking up on him was destroyed by Hugo. However, the Kumuzilla came up behind Hugo, to which Ronan pushed him out of the way, and took potentially fatal hits from it. It also attempted to kill Gaster and broke a building, trapping both Jessica and Gaster into rubbles.

Its shadow is seen later towering over Undyne, Hugo, and an unconscious Ronan as Undyne prepares to fight with it.


  • It was first mentioned by Zachary.
  • Its name is confirmed to be Kumuzilla, as ridiculous as that sounds.
  • When the creature is shot by something other than DETERMINATION and if it causes damage, it breaks off into smaller creatures.
