So we were brainstorming for Colette when this happened. 
Name: Zoe Natasha Llyan
Faction: Team Liberty
Hometown: Floe Island/Four Island Town
Age: 12
Birthday: September 19
Appearance: Zoe is of average height and has bright blue eyes. She has light beige hair, a little less wavy than her sister's, which falls about halfway between her shoulders and elbows. She wears her hair in a ponytail and is often seen with a decorative Chrysanthemum flower in her hair. The color of the flower changes every so often as she continually picks out new flowers. Currently she has a yellow flower to match her sister's sunflower. She often tries to put her hair up in a 'Lucario Ears' style similar to her sister; however, the tufts of hair often end up falling flat on her head, much to her disappointment. Zoe wears a white long-sleeved t-shirt with white and sky blue striped sleeves. She wears a silver bracelet on her right arm, a birthday present from her sister. Around her neck she wears a golden locket with a picture of her sister Colette. She also has blue Capri jeans and white sneakers with a splash of blue. Although Zoe herself cannot read auras, to those who can her aura appears a deep blue, smooth compared to her sister's jagged aura.
Personality: Zoe's parents are high ranking Liberty agents, and her older sister has been away in Kalos training to become an Aura Master. As such, Zoe feels the need to prove that she is just as capable as her sister and parents. Although she has a very close bond with her sister, she can't help but feel like she's living in her sister's shadow. And yet she idolizes her sister and wishes she could be just like her. After receiving her Fennekin from Colette, she caught her Meditite and Feebas in an attempt to emulate her sister's team.
Overall Zoe is much more trusting of others than Colette, which is natural given that Zoe doesn't have even a trace of aura powers, so she doesn't know how untrustworthy some people can be. She often fantasizes about having aura powers and being as important as her sister. As such she can come off as a bit aloof, often having her head in the clouds. Once someone gets to know her, however, she is a very sweet and caring girl. She tends to create nicknames for people; she affectionately calls her sister 'Dog Ears' in reference to her tufts of hair that stick up like Lucario ears, and a few years ago coined the name 'Collie' as a shortening of 'Colette.'
Background: About a year after Zoe was born her older sister Colette was sent to Kalos to hone her aura powers. Zoe grew up on Four Island, where her parents were often busy helping Team Liberty. As such, Zoe was placed in the schooling system that all children of Liberty agents go through. Every summer she and her parents would travel to Kalos to visit Colette. The two sisters often played 'Rockets and Liberties.' Since Colette's birthday is in the summer, they were able to celebrate it as a family every year. However, Zoe was born in September, so Colette would send her gifts, starting with her second birthday. She received the gifts at the end of their July vacation but always had to wait until her actual birthday in September to open them. For her fifth birthday she got the golden locket that she always wears around her neck. For her tenth birthday she was allowed to open her present in July while they were still in Kalos -- she received a Fennekin, her first Pokémon, who she nicknamed Esmeralda. One day while playing with Esmeralda on Four Island, Zoe came across a Meditite who fell on her head after losing its focus in meditation. Recalling Colette's Mienfoo, she decided to catch the Meditite, who she nicknamed Merida. For her eleventh birthday she received a fishing rod. Knowing that Colette had fished up both her Squirtle and Clauncher, Zoe would spend hours fishing on Four Island Beach. She didn't have as much patience as her sister, but eventually she managed to fish up a Feebas, who she nicknamed Eilonwy. For her twelfth birthday Zoe received the silver bracelet that she wears on her right arm. Zoe has just returned to Four Island from her annual vacation, which was earlier than normal -- they actually left on Colette's birthday rather than a few days after. Stranger still, she did not receive a present for her thirteenth birthday, which is only a couple months away. This left Zoe curious, although she didn't question it too much, assuming Colette would mail her a gift in time for her birthday.
Pokémon: Fennekin (Esmeralda), Meditite (Merida), Feebas (Eilonwy)
Species: Fennekin (female)
Nickname: Esmeralda
Trainer: Zoe Llayn
Appearance: The red tufts coming out of her ears are not as pronounced as with a typical Fennekin. The red fur on the tip of her tail also covers more of her tail than usual.
Personality: Esmeralda is a very jolly Pokémon, as upbeat as the Llyan sisters. She sympathizes with Zoe wanting to prove herself, but Esmeralda would be just as happy simply relaxing and playing on Four Island.
Ability: Blaze
Specialty: She has a powerful special attack
Known Moves: Scratch, Ember, Psybeam, Fire Spin, Light Screen, Wish (egg move)
Species: Meditite (female)
Nickname: Merida
Trainer: Zoe Llyan
Appearance: Her head is more rounded than most Meditite
Personality: Merida is a little hasty. She is easily distractible and as such has a hard time focusing on her meditation. This is often a source of concern for Merida as she struggles to prove that she's just as capable as any other Meditite.
Ability: Pure Power
Specialty: Merida is better at physical attacks than special attacks, although she's still clumsy. Her special attacks are below average due to her issues with meditation. Every now and then one of her special attacks will be more powerful than intended.
Known Moves: Meditate, Confusion, Feint, Calm Mind, Force Palm, Bullet Punch (egg move)
Species: Feebas (female)
Nickname: Eilonwy
Trainer: Zoe Llyan
Appearance: Her tail fin is more tattered and frayed than usual
Personality: Eilonwy is an adamant Pokémon, insisting that she is more than capable of fighting battles even when she is at a disadvantage (which is more often than not). She is a little stubborn in that regard, but one can't deny that she always tries her hardest.
Ability: Oblivious
Specialty: Eilonwy is very durable when it comes to special defense. Even if she can't do much to attack, she will still endure the battle as long as she can.
Known Moves: Splash, Tackle, Flail, DragonBreath (egg move)
