Muk (Japanese: ベトベトン Betbeton) is a Poison-type Pokémon introduced in Generation I.

It evolves from Grimer starting at level 38.

In Alola, Muk has a regional variant that is Poison/Dark. It evolves from Alolan Grimer starting at level 38.

Biology

Muk is a large, sticky, amorphous Pokémon, made of living purple sludge. It has two small eyes with beady black pupils. It also has an enormous mouth with a grey tongue and strands of ooze connecting its top and bottom jaws. While it has no visible legs, it does have two arms with three fingers on each hand. However, it typically keeps one hand tucked in while it extends the other hand.

It is a living biohazard, leaking toxins that instantly kill all plant life it touches. Even it being in close proximity to plants will cause them to wilt and die. Extreme caution is advised in avoiding any contact with this Pokémon, as an accidental brush up can lead to severe sickness. The effects of this Pokémon can leave the landscape barren for three years. In dirty residential areas where people throw trash into the streets, it is almost certain to appear. It will readily consume nearly any waste or refuse generated by people and Pokémon alike. It can be found in heavily polluted bodies of water, cities and factories. However, Muk's population has declined due to recent environmental improvements, leading some to believe that it will go extinct at some point.

Alolan Muk has a more vibrant coloration, consisting of green, pink, yellow, and blue. The green, yellow, and pink colors are capable of shifting downwards while the blue stays in place. Like Alolan Grimer, it has various white crystals protruding from parts of its body, especially from its mouth and fingers, giving the impression of claws and teeth. It has blue pupils, black coloring behind its eyes, and a light blue tongue. Its vivid coloration is a result of the garbage it eats, which causes chemical changes in its body; these same chemical changes are thought to be the cause of its unending hunger. It's unexpectedly quiet and friendly, but if it is not fed trash for a while, its hunger will compel it to destroy its Trainer's furnishings for food. The crystals covering its body have a tendency to break off, which makes it extremely difficult to deal with due to the concentrated toxins contained within them. This variant of Muk does not produce the foul stench that the standard version is infamous for.

Trivia

• Although Muk's body is very poisonous, it doesn't seem to harm Ash and the others when Muk is 'hugging' them. This is probably because it is able to control whether it gives off poison or not, similar to how Ponyta can choose whether or not to burn the person that touches it. Croagunk is another Pokémon which is able to control the amount of poison it uses via its fingertips when using Poison Jab, or Sharpedo activating its Ability, Rough Skin.
• Muk is tied with Mew for the shortest English name out of all Pokémon.
• Muk shares similar traits to Weezing and Garbodor. All three Pokémon are pure Poison types with a single pre-evolution, roughly the same base stat totals and evolution levels, and appear to be based on a different kind of pollution; Muk being water pollution.
• Muk has the highest average Performance of any fully-evolved Pokémon.
• Alolan Muk and its Alolan pre-evolution were designed by Hitoshi Ariga.

Origin

It appears to be a pile of living sludge. Muk may also be based on the imagined fear that heavy pollution, caused by the leakage and/or improper disposal of toxic/radioactive waste, may result in the creation of new and undesirable life.

Alolan Muk may be based on an oil slick, particularly the rainbow colors it produces when it mixes with water.

Name origin

Muk is a corruption of muck (generally something filthy).

Betbeton may be derived from べとべと betobeto (sticky) and ton.
