Plumbers

Plumbers are a species of sentient, sapient primates, closely related to humans, although possessing many distinct abilities and weaknesses which set them apart from other primates.

They once had a thriving, technologically advanced civilisation that spanned the globe, which collapsed in a cataclysmic event known as 'Pipe Fall'. Only a small number of them survive to this day, attempting to blend into human society.

Abilities
-Extreme endurance, having been seen running, jumping and brawling for as long as 48 hours without rest

-Breathing underwater

-Subconscious gravity manipulation, allowing them to leap high, and crush enemies below with their own weight

-Elemental aesthetic metabolis, being able to gain abilities from ingested material's lingering aesthetic association energy

-Backwards long jumping

Modern internal conflict
Surviving plumber populations have a lot of internal conflict about what their role in human society should be, the two emerging sides are known as 'Bros' and 'Fallen Plumbers' the former of which maintains the cultural values of ancient plumber society, and believe themselves a guiding hand protecting human civilisation as it develops, and the latter embracing human culture, especially their social Darwinism, which allows them to use their superior physical capabilities and longer lifespans to out compete humans in capitalism, amassing massive wealth and living lives of selfish hedonism.
