Undyne is a boss in Survive The Disasters 2.


Undyne is a custom boss enemy that originates from the popular game Undertale. In-game, her appearance is of an armored humanoid wielding a blue spear. Undyne spawns from a random enemy spawn point, chasing the closest survivors and doing special attacks:

  • Spears: Undyne summons a wave of blue spears that travel towards the nearest player. They deal 35 damage on impact and will attack to any surface or structure, disappearing after about 10 seconds.
  • Slash Wave: If Undyne is in enough range of a player, she uses her main spear she wields and creates a green wave. It cannot pierce through walls, but is dangerous (deals 60 damage).

Hyper Undyne

Hyper Undyne randomly spawns large spears from the sides of the map and travel across in a grid pattern. The larger spears from outside the map deal a staggering 80 damage. Undyne herself spawns spears faster and can use the slash wave ability in a quicker manner.

Disaster Memo Information

"Undyne, the leader of the Royal Guard, attacks all survivors! Each spear on contact inflicts 35 damage. She's can be outrun due to her low walkspeed(20), but can easily chase you down with her spears. Spears cannot pierce through cover. If you're close to her, she will do a slashing motion that creates a green wave dealing 60 damage on contact. The green wave however, pierces through parts."

"Compared to standard Undyne, she has an extra attack that summon giant spears outside the map. Those do 80 damage. She can also spawn 16 ~ 24 spears instead of the standard 3, targeting the nearest survivor. Those spears are powered to do 60 damage as well. Her walkspeed is 28."


  • Undyne is a direct reference to the famous game Undertale and one of its characters, Undyne.
  • If you defeated Undyne, you would get the "Justice Unserved" badge. This badge, however, was disabled in Version 39.
  • If Undyne is defeated, a death message appears upon the players screen.
  • Each of Undyne spears remain for about 10 seconds after being thrown at the nearest player.
  • Undyne is the hardest boss to kill, considering it's the smallest.
  • Undyne is the only boss to spawn from enemy spawn points.
  • Undyne is the only boss in which a noise is played upon a player's death. The noise is the sound that plays following a GAME OVER in the game Undertale.
  • If you touch any of Undyne's spears in the air, you still take damage.
