Deuce Spade is a mackerel merman. Most of his skin is blue, with his underside, belly, and face being a much lighter shade. His hair is a sort of purple shade of blue and his eyes are more on the cyan scale. He is about 9 feet long with 4 feet being his black-striped tail and his extra foot of black fins. He is protective of whoever he saves as he hates seeing sharks bully helpless creatures.
