Head and legs: Helix
Hair: Cover Girl
Torso and upper arms: The Baroness (Attack on the Pit)
Lower arms: Scarlett as Glenda
Feet: Diver Baroness
Harpoon gun: Torpedo
Knife: ???
Communications device: NS Tele-Viper
Design:
Mara appeared as a Cobra diver turned surgical mishap monster turned Shipwreck's love interest in the Sunbow cartoon series. The pieces used here, when framed with the flipper feet, pass for a wetsuit.
Colors & Paint:
Unlike the cartoons' mostly blue color scheme, I went with a blue and aquatic green color set. The eyes, which looked like normal human eyes in the cartoon, needed some more menace in them, so they became solid black.
Modifying & Sculpting:
The Agent Helix hair was removed and replaced with modified Cover Girl hair. The throwing stars were removed and then hidden by the communications device.
