Posting something old stuff for the lols
From left to right: Una, Twain and Tressa. THey are piranhas. If you have follow me for a while youll notice I have a weird trend of making trios with primary colors.
Since they always work together they share the same rank in the Locke jaw pirates, They command a small army of weird piranha beings (imagine the salmonids from splatoon 2 but as piranhas instead)
Una is a bit of a joker, the most animated out of 3 and the leader (despite Twain saying otherwise) she's the main brain, which isnt saying much.
Twain is the muscle, and the most agressive, Just tell her what she has to do and she'll destroy the task, quite literally.
Tressa, the chillest sister, but can be just as vicious as her sisters. She's usually just following order, either from Una, Shui or the captain, She prefers to just go with the flow.
