The next of water is fire. He is a Mako named Gouen.(轟炎, 轟=roar, 炎=flame)
Number of Mako's color is eight in all, and I designed fifteen Makos for my novel. And individually I like him best of fifteen Makos.
However, I was not able to represent his color, texture of his fur, and vigor as I had imaged...OTZ
I must have thought of his flaming tail when I used a certain web browser of fox...
By the way, Gouen is Akamako(赤魔狐, 赤=red).

I uploaded three pics including different version.

here: Have ignited
next: Just before ignition
