Karen

Karen is the Keeper of the Purple Pearl and Mermaid Princess of the Antarctic Ocean, which is also known as the Southern Ocean.
Karen has a twin sister named Noel who is Mermaid Princess of Artic Ocean. After finding out that Noel has become captured by the sea monsters, Karen sought out on a quest to find her and meets Lucia, Hanon and Rina. She initially despised Rina and blamed her for leaving her sister behind and running away on her own until she learns the truth, but she is still reluctant to being with them. But whenever she needs to, she will appear to assist her friends.
In the end, they work together to confront their enemy and Karen finally frees her sister, along with Coco, the Mermaid Princess of the South Pacific Ocean. Karen's name means pure. Karen is a mature person and dislikes Rina for what she did.
Though Karen lacks a real love interest like Lucia, Rina and Hanon, she had fallen for a man named Subaru in the anime.
Karen can mean 'pure' in Greek.

Caren has three forms: her mermaid, human and Purple Pearl Voice form.



Her mermaid form follows the trend of all the other mermaid princesses, with two pearl bracelets around her right wrist and tail.











In her human form, her light purple hair becomes a wine purple color, and her eyes also become a brown color (in the manga, her hair in the human form is wine purple, her eyes are blue). She wears a necklace with her pearl inside it like the other mermaid princesses. In the manga, Karen (in the human form) first appears in chapter 9. She is 168 cm and weighs 120 lbs. She was born the 14 of February of 1984.






Lastly, there is her idol form, her Purple Pearl Voice.
Her costume is a white short strapless dress with purple ruffles down the one side and it is above knee length with purple trim at top. Her bow is a slightly brighter shade with lighter purple ribbon on the end. Her gloves are white with purple cuffs that extend to her mid arm and her high-heeled boots have the same colors. She has a purple and white barette in her hair.

In the anime, Karen shouts "Purple Pearl Voice!" to transform. In the manga, she can transform at will with no incantation.
In her idol form, like Lucia and the others, Karen can use her singing voice to get rid of enemies.
Her song is 'Aurora no Kaze Ni Notte', and in the manga, at the end of her songs, she uses 'Cutie Hot Pitch'. In the anime, she uses 'Love Shower Pitch' with the rest of the mermaids.
Her song is Aurora no Kaze Ni Notte:http://www.youtube.com/watch?v=7UYNEwG_HrU
But in Spanish, the first version of this song is "dangerous":http://www.youtube.com/watch?v=n1gAQZuikmA
