Fluttershy

Physical
A buttery yellow pegasus pony, with a turquoise eyes and a salmon pink mane that naturally drapes down one side of her face; her large tail Incredibly small, even for a pegasus, her mane, tail and wings combined make up over half of her surface area.

Her cutie mark depicts three pink butterflies, a representation of her love for animals, beautiful heart, and delicate personality.

Biographical
An extremely shy and timid pony, but undeniable the kindest at heart than any other pony. A devoted animal lover, she will often come out of her shell if there is an animal nearby.

While soft and gentle, Fluttershy is very fragile, and can rarely assert herself in bursts of emotion.

She is also afraid of heights, regardless of her ability to fly.

Unbeknown to her, or anyone for that matter, her voice is actually enchanted, due to an unusual birth defect where her mana well developed within her throat, instead of her brain.

Backstory
Born and raised in the floating city of Canterlot, Fluttershy was always the one left out, timid and delicate, she wouldn't start conversations with strangers, and always kept to herself in fear of judgement and mockery. She grew up without friends, until she met Rainbow Dash, whom surprisingly grew close to the pegasus, and chose to stick by her, even during the awkward silences.

While supporting Rainbow Dash in a race, Fluttershy was accidentally knocked back and fell out of the floating city and plummeted to the ground far below, her fear of heights causing her wings to cease up and she would have died, if she hadn't been miraculously saved by a swarm of thousands of butterflies, drawn to her screams. She then discovered the wonders of nature on the ground, and befriended animal critters, communicating with them via her enchanted voice.

She later moved to Ponyville and took on a part-time job as a nurse, alongside being a freelance animal carer.

The events over MLP:FiM's first 3 seasons then occur.

Ongoing Story
Alongside the rest of the group in search of the Titan's Orb shards, Fluttershy has taken on the role as the group's medic, and is supplied with surgical equipment and various drugs, lotions and herbal tonics, her main supply being that of Kuphila Amanzi, a healing gel created by Zecora the zebra.
