All we need is her and she could complete the small group of Bolts. Yes I do understand there is more than three Wonderbolts in the team. Fleetfoot would be completing the small promotional team, the faces known to most of ponies. She is right beside, Spitfire and Soarin'. As Soarin' and Spitfire are close, I can only see the three of them together just being the closetest of friends. Since they do spend a lot of time together and from time to time, travel together.
Personality wise? Whatever you want really. Just understand Wonderbolt are looked upon greatly and are a giant role model for many many ponies.
OH! She is also the fastest little thing you have every seen. Even faster that Spitfire.
The Fun Has Been Doubled! is a My Little Pony: Friendship is Magic moderate-to-advanced forum roleplay. Set after the events of the fifth season, we currently have no overarching plot. Instead, we simply have created the world of Equestria for you as a giant playground to have fun in and to explore the magic of friendship. Canon characters and original characters are available for you to play as, both ponies and non-pony species alike! Just remember that we are account-per-character and we'll be fine!
So why don't you stay for a while, look around, and let us know if we should get a welcome party started for you.
