Koru Flame

Her mother was a pegasus mare and her father was a wizard dragon, how-ever, she was left at an orphanage as a newborn foal, due to the lands between the dragons and ponies being at war, and neither parents could look after her.

From an early age, when she learned about her parents, she devoted all her time to become a powerful fire and wind wizard and to search for her parents, knowing they went into hiding. 

When she was at the age of six, she was discovered by the armored wizard, Erza Scarlet, who took her in and practically raised her as a big sister, and when she was old enough, Ezra took her to join her guild, Fairy Tail, and since then, Koru has come to see every single member as family, though, she still is searching for her parents.

Despite her being an orphan and her obvious differences in appearance, she has a happy go lucky kind of attitude, but when she gets into a fight, she goes in head first without thinking, often causing a fair bit of collateral damage, but then, that's just like every other member of Fairy Tail, which just helps her be like the family that is the guild.

She is a pony/dragon hybrid
