Gums (ハグキ, Haguki) is a Dragon-level Mysterious Being and an executive member of the Monster Association.


Gums is a large, rotund monster with two arms and two legs. Its head contains no features other than an incredibly large mouth that lacks any lips. In the webcomic, he has a more humanoid body shape.


Gums appears to be incapable of speech. As it is called into a meeting, it seems to be intelligent enough to understand speech. However, it is incredibly gluttonous and driven by the desire to consume.

Gums goes toe-to-toe with Pig God

Immense Strength: Gums is able to use its huge mouth to chomp through things like metal and debris with ease - it managed to swallow Pig God, a hero known for eating monsters, to defeat them. It also appeared to be gaining the upper hand over Pig God in its fight with him.

Enhanced Stealth: Despite his bulky and pudgy appearance, Gums was able to sneak up on and take Pig God, an S-Class hero, by surprise.

Elastic Jaws: Gums can stretch open its mouth to inhumanly wide proportions in order to consume large masses such as swallowing the immense Pig God in a single bite.
