General bio:
 
Gem’s a hot-head, brash, short-tempered, competitive dragon-pony. She could be Rainbow Dash’s double, so much so that Rarity tried to make her civilized like her sisters but it was no use, everything her and her sister loves, she hates, and vis-versa. Gem is always moving, always flying, and just keeps racing. She tries to be the best at everything and thinks she is pure awesome ! She never backs down from anything and her appearance never bothered her, unlike her sisters who had troubles when they were younger. Gem’s response was usually brutal or harsh when anypony made from of her or her family. Why is she so much like Rainbow ? Because she spent a lot of time with her when she was young. Gem got into fights as a kid because of how someponies treated her or her sisters and twin brother and Rarity was never able to reach her or make her do things in a different way. Spike then suggested to talk to somepony with past experience as a bully fighter and that’s when they would take her to Dash. Gem Stone spent a lot of time with her and her daughter Lightning to be able to focus her rage in a more ‘awesome’ way as Rainbow puts it. Ever since she heard her stories and adventures, Gems wanted to become like Rainbow. Lightning and GS would hold competitions and such to prove that they would grow up to be the better Rainbow dash (to her delight). Gem Stone is fast, very fast and an excellent flyer, she is very close to making a Rainboom. She is able to use her surroundings better than a Pegasus Pony because with her claws her is able to maneuver in ways that they can’t.
 
Relationships:
 
Loves Rainbow Dash very much, she is like her idol and admires her so much. Lightning Blast is her best friend and she sometimes hangs with Dawn for Flight Competitions. Doesn’t really get along with her sisters or mom though it’s alright with her father, doens’t really understand her twin but will defend him if bullied, has some special bond with him since birth.
 
Talent/Abilities:
 
Has a Cutie Mark of three gems of different colors. She is a born flyer and will someday be even the best.
