At last, the antagonist of Blade´s story.
Neptune is a project created by a scientist, who gave him the capability for fights, more strenght and cold. He´s considered a Hunter Project, se´s more like a pirate too, he has a floating ship as an advance technologic.
So evil, and cold, the perfect bad guy for this story.
The only thing I like is the idea of adding another fin on his head and arms to make him looks different from the other concepts of sharks that I´ve been watching.
Once again I must thanks to
for another suggestion, thanks man ^ ^
