Princess Marina

Marina is a mermaid that is it's home is the Ocean in Planet Dens.

Appearance
She has an hourglass figure and fair skin. In her childhood, she used to wear a lavender tube top. Her lips were the same color as her skin. From the waist down, she has a green tail with paler green, translucent fins and wears a brassiere made out of lavender seashells. She has large, deep aqua blue eyes and full red lips. Her most defining feature is her long, red hair that matches the color of her lips. In Little Mermaid's Island, her seashell bra looks more like a strapless top that covers her belly.

Abilites

 * Underwater Breathing: As a mermaid, she is also able to metabolize oxygen from the water, which negates the need to surface, though she is certainly more than capable of breathing on land.
 * Speed Swimming: Also, she is capable of swimming at a much faster rate than humans or even certain marine creatures in terms of undersea travel, or sea travel as a whole due to her half-marine status. Like dolphins, she is capable of leaping out of water at great heights. For example, she was able to get to Triton's Greenland Palace from Denmark (the implied location of Eric's kingdom) in less than a day, as well as getting from Atlantica to Norway in the episode "Metal Fish" in a similar time fashion.
 * Because of her being a mermaid, she is also capable of speaking with aquatic fauna. She retains her ability even in human form, but whether her abilities of superhuman strength and endurance were retained upon becoming human is debatable.

Background
In the Ocean, Marina and her fish friend Flounder swim through a shipwreck where they salvage human items. During their adventure, the two are attacked by a shark, but Marina manages to outwit the vicious creature. After escaping the shark, Marina and Flounder swim up to the surface where they speak to Scuttle to identify human objects. Scuttle misidentifies a fork as a "dinglehopper" used to straighten their hairs and a pipe as a "snarfblatt" used to make music. Meanwhile, in the Kaede Arc, Marina tearfully swims off to her secret grotto, where her collection of human objects, from books to other regular objects, such as globes, mugs and chests of jewels, is kept. She feels that collecting human objects isn't enough and gets more curious about the world above the ocean, even expressing her desire to actually live among the Sea Creatures. She then spots a male human by the name of Kaede was escaping with it's Family from the Terrible Dog Fish and remarks to Scuttle how she has never seen a human this close before. Just then, as the Terrible Dog Fish tries to catch Kaede and his Parents, Marina looks around for Kaede's Mother and unconscious in the sea. She carries her to the shore where she founds Kaede dead after escaping the Terrible Dog Fish. Devastated, Marina breaks down in tears in her Grotto. Marina is then turned into a human and is helped to the shore by Flounder and Sebastian due to her inability to swim. At the shore, Marina is found by Shippuden and her sheepdog Max, who leads his master to her.
