Raekin is a creature of the sea. Her body is covered in fins that while on land act as her clothing, and while underwater, are useful for propulsion. From the top of her head, she has two fan like fins known as her crown fins. Her forehead is bare with two strong brows visible. Her skin tone, made of varying shades of green, is flecked with spots of dark sea green and dark teal. Her entire body is hairless, but the four tentacles straight off an octopus are aesthetically the same thing as if she had hair growing out of her scalp.
Her largest fins are by far the two wing like structures on her back that are collapsible like all of her fins. Over her chest are two large fins that sprout from under her arms. When detracted, these fins hold flat against her arms. Her elbows are tipped with wings that come in handy when steering underwater. Hands and feet are also used in that task, looking much like frog's feet with the webbing between long thin fingers and toes. The last set of fins sprouts off opposite sides of her legs, aiding in moving water when she kicks.
