I was waiting for one of these!
Name: Snowflake
Mare or Stallion?(Pony terms for female and male, respectively): Mare
Pony, Pegasus, or Unicorn?: Pegasus
Appearance: (Since I have no picture) White body with a silky icy blue mane and tail. Her eyes are light blue, and her cutie mark is a small gust of wind full of snowflakes.
Personality: Snowflake is kind to other ponies, but daring. If another pegasus challanges her to race, she accepts imidiently. She also is a childhood friend of Rainbow Dash, Fluttershy, and White Lightning, and she is kind mostly to them.
Bio: Snowflake was a weak flyer when she was younger, casuing her to one day fall in danger, literaly. She was about to fall off a cliff, but Rainbow Dash caught her. She then introduced Snowflake to Fluttershy and White Lighting, and showed her that daring is the best personality. Afterwards, Snowflake helped winter to come, allowing her to gain her cutie mark. However, she and Shadowsnow swore to be each others foes.
Sample Post: Snowflake flew over the crowd and landed next to Fluttershy. She nudged the shy pegasus and exclaimed "Don't let your shyess kick in, girl, this happens every year. You and the birds will do great.", only receiving a nod from her friend. Snowflake chuckled and landed back on the ground, watching a pegasus pony emit snow from her wings, entertaining the little ones. Then all the ponies were hushed. The princess was about to appear!
What a surprise to Snowflake when a dark alicorn appeared instead! She growled at the intruder, reconizing the evil one as Nightmare Moon. After a speach from Nightmare about the Elements of Discord and night lasting forever, Snowflake sprung up from the floor, surprising everypony. She wasn't much of a springer even when she was really daring. Snowflake glared, focused it on Nightmare Moon, and yelled, "You dare try to make night forever? No plants will grow, no trees, NOTHING! You wanna make night last forever, you gotta go through ME first! Come and get me, you evil hag!" Nightmare chuckled and hit her with lightning, causing her to plumet. Snowflake ran out then, Nightmare laughed behind her.
As she ran, Snowflake saw two ponies heading into the forest, so, being a pegasus who loves to always get into the action, Snowflake followed them. She flew up to get a better view, and almost shot herself across the sky when she reconized one of them as Shadowsnow, her sworn enemie. The shock soon was replaced with anger, and the white pegasus shot down in front of them as fast as lightning. She focused a glare on them and growled "Where are you going? Because if you want to see Dragon Slayer, I can't let you do that.", then she turned to Shadowsnow and added, "Especially you."
(I know I'm probably late on this, but really. I haven't read the whole thing yet.)
