Fairy Tail

Carla's home world is Edolas, kingdom of Extalia, and she's one of the Exceed. While in her egg, Carla's power of precognition activated. She mistakenly believed she had a mission to go to Earth Land to kill a Dragon Slayer. In actuality, the discussion she heard was a lie to the people of Edolas, to cover up the Queen's plan to save the Exceed race, as she knew Extalia would be destroyed. Sometime before the start of the series before Carla was born, she was sent da her mother, Queen Shagotte, through the Anima to escape a future disaster. One giorno Wendy found her egg, and when she was born she saw visions involving the Royal Army of Edolas. Since her birth, she kept believing she was sent to kill Wendy.

Lucy was born in the once extremely wealthy and powerful Heartfilia family. Her father and mother were originally part of a merchants' guild called 'Love & Lucky' where they met; they decided to become independent when Lucy's mother, Layla, became pregnant. They chose her name when they noticed that the sign of the guild was missing the letter "K", and instead read 'Love & Lucy'; it made an impression on them, so they decided to name their daughter after it.

Back in her home, Lucy shared a good relationship with the staff in the estate as well as, presumably, her mother, until she passed away when Lucy was around the age of ten in the anno X777. However, because her father was overly obsessed with his business and money, he had neglected his daughter, which eventually led her to run away from home just over a anno before the beginning of the story.

Years ago, before Happy was born, he was taken away from his parents, Lucky and Marl da the Queen of Extalia, Shagotte, to carry out the Dragon Slayer assassination plan. In actuality, sending him to Earth Land, along with all the other Exceed eggs, was to allow him to escape a future disaster in Edolas.
In X778, Natsu found Happy's egg in the East Forest of magnolia Town. Natsu then took it back to the guild where he and Lisanna raised it together every day. One night, Elfman took it to keep it warm and the successivo giorno when he brought it back, it began to hatch and out popped a kitten with a pair of wings. Happy's first word was "Aye". Natsu gave him the name "Happy" after Lisanna pointed out the change of the atmosphere from anger to happiness after Happy hatched from the egg. Despite everyone else seeing him as a cat, Natsu thought he was a Dragon.
