I'm not from Mars.

got this done at last i’msrghs just take i t

here’s some headcanonss

all mers are more or less magic and can have special abilities of different kinds, also if they really want to go on land and live as humans for whatever reason they can learn to morph their tails into legs for a short while, but if they spend too much time as humans that’s not reversible anymore uvu

there are some humanoid fish people living in the sea, they’re a bit smaller than mers and Vriska likes to hunt them at times because she’s a lil shit

and then they have some sort of attack/defense mode (or also if they go into really deep sea) where they are a bit more monster-like and the markings on their bodies become glowy 8’)

the last pic is Sollux btw and the first one is Terezi and Karkat

(everyone not in the set is more mers or humans, I didn’t have anymore space nor patience)

also what if Gamzee
