Forgot to mention, they can come in various forms of larger sea creatures. Dolphins, other sharks, Manta Rays, hell, go in for the extinct sea creatures if it translates well into a Zora design. Just not regular fish.
Backround on the Zora.
The Zora are amphibious creatures from the Nintendo series The Legend of Zelda. The Zora here are specifically based from the latest installments to the series, Breath of the Wild/Tears of the Kingdom. I will show some example photos of Sidon and Yona(Shark and Sea Angle(??)) for reference. Create your own Zora OC! Zora can come in a variety of colors, mostly shades of blue, green, and red. They also have colorful fin frills. They are excellent in the art of spear fighting. The Zora are also excellent swimmers who can even swim up raging waterfalls. Have fun, and show me what you make in the comments! (EX of Lynn, my Zora character, in top-left corner.)
