"You're gonna have to try a little harder than THAT."
- Undyne
Undyne is one of seven bosses from Survive The Disasters 2.


Undyne, the leader of the Royal Guard, attacks all survivors! Each spear she launches deals 25-35. She's easy to outrun, but can easily chase you down with her spears. Her spears go through only breakable parts.


  • Her spears will still remain after shot and last for about 15 seconds.
  • If you defeat Undyne, you get the "Justice Unserved" badge.
  • If you kill Undyne in-game, a death message sometimes can be summoned in the player's screen, and always in Mystery Disaster. Before the Version 1.25, the message were always summoned.
  • Undyne and Alexnewtron are tied for being the smallest bosses. Because of that, they are more difficult to hit, especially Alexnewtron, as he constantly jumps.
  • Undyne is the only boss to spawn on Enemy Spawn Points. Make note of them when the text appears!
  • If you run circles that move outward around Undyne with decent speed boost, it makes it easier for other people to hit her as she won't move due to her AI targeting the closest person to her.
  • There is an unknown sound that is played each time Undyne has killed someone, rather other than another boss.
  • Undyne is a direct reference to the famous game Undertale character Undyne.
