Parkour Civilization headcanon / AU: The art of parkour is a dance.
To some people in parkour civilization, a deep part of their very instincts make it so that their styles of Parkour are almost like a unique dance.
I imagine EMF parkours in kin to ballet, elegant leaps and spins, always on their toes, subtly bowing wherever they do something impressive. (I love this dainty little void being so much <3 )
Seawatt is naturally very different. While he is one of the few people who doesnt put a lot of style or emotion into his parkour, high running emotions can accidentally pull it out of him. I would say that the rhythm of his parkour is closest to dancehall dances.
Evbo's parkour changed each level of civilization he was on, because each level he explored, he expiramented with the new styles and rhythms he saw from other people around him.
I love imagining Clown Pierce's rhythm, because I can see his being some kind of creepy contortionist thing. Like bending his legs over his body as he walked, randomly doing random backflips or handstands just to freak people out. He moves scarily slowly, until he's got you into a parkour race, then he moves like a f-ing track star, already at the end of the race before you even make your first jump.
I don't have much to say about the Old Man, except that behind closed doors, he tap dances/parkours like no one is watching.
(Let me know in the comments or my inbox if yall want me to write some kind of short fanfic about this :>
Btw, I would kill for the first person who sends me art of this au/headcanon.)
