Soooo....
I noticed this.
The salmonids from Splatoon.....
Are very simular to the Orks from Warhammer 40k.
(Anything in these are a note or explanation.)
-the biggest is the boss! (The King salmonids are huge and are Implied to be actual kings)
-CHAOS
-Rag tag raids
-steal weapons (hey,the Salmonids has to get all their pans somewhere....)
-The Red ones go fasta (Slammin lids wear red hats and every Lesser Salmonid has red hair)
-Purple is Sneaky (Snatchers have Purple hair. It's also a common joke that the reason why you see no Purple Orks is because Purple is a Sneaky color)
-constantly at war.
