Rainbow Dash

Rainbow Dash is a character from My Little Pony- Friendship is MAGIC. She is a Pegasus (has wings). She is one of the main characters from My Little Pony- Friendship is MAGIC. She absolutely LOVES to fly, and especially win! A lot of times she is a show-off, and can be very boastful. If there is anyone more awesome than her, she'll be very jealous. However, her element is loyalty, she will stand up for her friends no matter what it costs her. If she had a choice of achieving your dream and helping your friends, she will never leave her friends hanging. Rainbow Dash lives in Cloudsdale, but spends most of her time in Ponyville with her friends. She is the only pony who can perform the SONIC RAINBOOM with her awesome flying skills. She and Applejack always fight on whether who is the most daring pony, however Applejack never brags about it. Rainbow Dash is brave and fearless!!!😁🏆
