Miasmoros is a large toxic sludge creature that serves as a major roadblock to Kirby in the games in which it appears. It resembles a sickly-colored mass of goo with yellow eyes, a gaping mouth, and fungus growing on its back. It is unclear if Miasmoros has a more solid body underneath the goopy mass, or if it is entirely viscous in nature, but it appears to be a distant relative of the Galbo-family of monsters.

Miasmoros's name is likely a portmanteau of "miasma" and "Galboros", further cementing its relation to the Galbo-family.

Game appearances[edit]

Kirby: Planet Robobot[edit]

Miasmoros first appeared as a Mid-Boss in Kirby: Planet Robobot that yields the Poison Copy Ability when inhaled. It is encountered somewhat infrequently, not appearing until the laboratory stage in Resolution Road. It also appears as Miasmoros 2.0 in Access Ark - Stage 7 EX, Meta Knightmare Returns, and The True Arena. It serves as an effective replacement for Flame Galboros from Kirby: Triple Deluxe and Water Galboros from Kirby's Return to Dream Land, as its basic body plan and moveset are largely the same as its two cleaner predecessors.

When fighting its regular form in Kirby: Planet Robobot or in a Tough Quest in the Kirby Clash titles, it attacks in a fixed order on loop as follows:

  1. Stomp Jump
  2. Poison Ball
  3. Stomp Jump [homes in on Kirby's positoning]
  4. Poison Wave x2

After losing enough health, it abruptly switches to this fixed order on loop as follows:

  1. Poison Tackle
  2. Stomp Jump [to one side of the stage]
  3. 3D Poison Spray
  4. Junk Poison Ball
  5. Poison Wave x3
  6. Stomp Jump [to center of the stage]
  7. 3D Poison Spray [around the stage one-and-a-half times]
  8. Junk Poison Ball
  9. Poison Tackle
  10. Poison Ball x5


In Kirby: Planet Robobot, Miasmoros can be found in the following levels and stages:

Team Kirby Clash Deluxe & Super Kirby Clash[edit]

Guess who's oozed back onto the scene! The only justice!
— Tougher Quest flavor text from Team Kirby Clash Deluxe and Toughest Quest flavor text from Super Kirby Clash

Miasmoros appears twice as an enemy encounter in Team Kirby Clash Deluxe and five times in its successor Super Kirby Clash. It is notorious for its potent poison vomit, and its ability to leave toxic puddles on the ground as it moves. Its overall appearance is largely unchanged since its debut, whereas it is now missing the pipe and wood plank it used to have in its back. In Super Kirby Clash, Miasmoros can be found by itself or paired with Hornhead and King Doo to form Team Triple Threat.


The evil ooze contaminating the land. It'd be OK if it were only slimy, but the putrid pollution is a bridge too far!

The following are all of Miasmoros' attacks in Team Kirby Clash Deluxe and Super Kirby Clash. Note that most attack names are from Japanese strategy guides relating to its appearance in Kirby: Planet Robobot.

Miasmoros' attacks in Team Kirby Clash Deluxe & Super Kirby Clash  
Attack Description Variants
Stomp Jump
Miasmoros jumps off the ground and lands somewhere else. The size of its leaps can vary.
Poison Ball
Miasmoros opens its mouth and spits out a number of toxic goop balls. These can be destroyed using attacks. How many get spat out can vary.
Poison Wave
Miasmoros opens its mouth and spits out a number of goop balls that roll across the ground. How many get spat out can vary.
Poison Tackle
Miasmoros slithers across the stage, leaving dangerous toxic pools on the ground that linger for a moment.
3D Poison Spray
Miasmoros opens its mouth and creates a huge cone of sludge while spinning around. How much it spins around can vary.
Junk Poison Ball
Miasmoros fires off poison-covered junk. There are two variants of this attack; one where Miasmoros starts shaking violently, throwing out pieces of sludge-covered refuse as it does so, and another where Miasmoros opens its mouth wide and spits out a giant ball of sludge and junk which then breaks up into smaller ones.
