Miasmoros

Miasmoros appeared in 2016 video game called Kirby: Planet Robobot. Miasmoros is a mid-boss appearing only in Kirby: Planet Robobot. It is a member of the Galboros family and a somewhat toxic relative of the enemy Galbo. When defeated, it can be inhaled to get the Poison ability.

Miasmoros is a slug-like Galboros whose body appears to be made entirely of green slime. Brown sludge covers the top of its head and runs down its back, with large bits of metal and concrete debris emerging from the latter. It has large yellow eyes with a red tint around the outer edge and its slightly-slitted pupils.

Its upgraded form, Miasmoros 2.0, recolors its green sludge purple and its brown sludge green.

In Team Kirby Clash Deluxe, it appears similar to its original form, except that it has large bubbles/boils instead of metal and concrete debris.
