Eh.
Tell me anything you know about the clan. You know your own words, and shiz.
We a watah clan. fish mayne and stuff
lool jk jk.
ANYWAYS. My body is so ready for this.
So this of course is based upon the Gyojin of One Piece - the famous Fish People we have seen from Jinbei himself to Arlong and the others if you're familiar with those characters. The clan is based upon fish people and thus heavily focused on water related abilities. Basically we in a sense become fish people. We can breathe underwater as well as move quite fast underwater, have immunity to lower ranked water techniques (in my case D-Rank), and use some water jutsu without hand seals (at the moment this doesn't apply to me). We also have a protein that is naturally produced on our bodies that protects us from bacteria and other micro-organisms. Now we also have a form of water sensory allowing us to sense any body of water
except rain drops and water in the human body. And of course we have some physical enhancements making us 1.5x faster and 2.0x stronger. Whelp that is pretty awesome c:
Now Gyojin are quite well known for Gyojin Karate which is a form of water taijutsu which effectively takes advantage of the water particles in the air to create shockwaves at its most basic level. This is quite cool in that its a very unknown type of attack. Normal opponents usually won't see it coming. Of course there are other variations of this but all of Gyojin Karate is in some shape or form based on water.
The history of the Gyojin is of course as one would think heavily rooted in water release. A group of shinobi who had a love for water release lived near the ocean. They would spends days upon days researching the sea and becoming allies and friends of the creatures of the sea. Now this is where the story takes on an interesting turn which makes me think of evolution and natural selection and stuff. Basically because of the amount of time spent with the ocean creatures the humans began to develop and adapt to the sea itself becoming a mixture between human and sea monster. Now just with all humans these fish people attempted to use their new found powers for war and for their own personal interests. But they were defeated and forced back into the ocean by the Uchiha and Senju clans and would then plan their resurfacing years later C:
