Kinana

Kinana is one of the newest member of the Fairy Tail Guild, and the former pet of Oracion Seis Member, Cobra. Unlike most other members of Fairy Tail, she joined the guild as an employee rather than as a Mage.

Appearance
When she was transformed into a giant snake, her back was covered by violet scales and an egg shell-colored belly. Her eyes are green with black pupils. She was almost always in her snake form, but in battle she spread a pair of bat-like wings, which allowed Cobra to use her as a flying means of transportation.

Currently Kinana is a relatively short girl, and she is rarely seen without her overalls. She has a round face with short hair, often accompanied with a ribbon on her head.

History
When she was young, she was turned into a snake by an evil wizard. She was turned back by Makarov after the master realized that she was actually a human. Kinana had no recollection of being a snake when she was first turned back, but recently her memory as a snake has slowly resurfaced... In which she hears a voice asking to hear her thoughts.

Oracion Seis arc
"Cuberos" appeared with her owner Cobra when the Oracion Seis confronted the Light Team. When she and Cobra engaged Erza Scarlet in battle, Racer distracted Erza and she bit her, thus poisoning her.

When Nirvana's second stage was activated, she is shown with Cobra stopping Natsu and Happy from reaching Brain. The two teams engages on a midair battle above Nirvana.

Current Magic and Abilities
Kinana currently does not have any Magic Ability, however she is learning Take Over Magic. She is a really good singer.

Former Magic and Abilities
Enhanced Strength: "Cuberos" had enhanced strength. Her strength is enough to lift Cobra. She also knocked Natsu backwards quite a distance with just a snap from her tail.

Poison Generation: "Cuberos" was a very poisonous snake. One of her bites could kill a person. Cobra said that death from her poison is very slowly and painful. It almost killed Erza Scarlet. Cuberos was able to transform her poison into mist. Cuberos's poison served as a food source for Cobra.

Wing Generation: Cuberos also had hidden wings that allowed her to fly. When she generated her wings, Cobra used her as a mount.

Trivia

 * Her Appearance is based off Hiro Mashima's assistant, Kina Kobayashi. However, her overall isn't a frilly one...
 * In anime only it was shown, that "Cuberos" was Cobra's pet already during his childhood while he was a slave at the Tower of Heaven, however this was before Cuberos was revealed to be Kinana.
