Let's have a nice headcanon thread and rate one anothers'!
I always imagined a Shiny Samurott as a warrior with a different "rank" of service than the regular form, due to having different color armor and weaponry. Given what we now know about the Hisuian being a rogue warrior, what would the Shiny Hisuian be? Either he's an even more cold ronin by disguising and imitating the regulars, or he could be a reinstated military member who joined the honorable code again and carries out the original orders of the Unovans in a foreign land.
