Wave Chill: The older brother of High Winds, thinks he’s the smartest guy in the world but actually isn’t. Pretty cocky, but knows when he’s wrong. He likes Blaze but the feelings aren’t mutual. Rarely shows his soft side, but he does have one beneath his cold exterior.
 
Fire Streak: Also likes Blaze, causing a rivalry between him and Wind Chill. He’s extremely proud, almost like the “Jock” of the team. He pushes pretty much everyone around except Blaze and Spitfire. He’s very power-hungry.
 
Breezie: Can be mature one minute, and childish the next. Actually has pretty good leadership skills, but at the same time is very lazy and carefree. She loves joking around and seeing the world through rose-colored glasses. She has a bit of a complex because she has been mistaken for some mysterious mare named Surprise nearly all her life, so whenever the word/name is brought up she has a bit of a mental break down. XD Other than that, she’s fine. She leads a secondary squad on The Wonderbolts, which consists of herself, High Winds, and Blaze.
 
Blaze: She tries her best to keep everything on task in order to help her older sister Spitfire out, however she can get a bit off track at times, usually due to Breezie’s antics. She was Breezie’s first friend on the team, understanding her “Surprise-Complex” because she had been mistaken for her sister many times, and is constantly one step below her. For the most part, she doesn’t mind it though. She’s extremely caring, kind, gawky, and bashful.
 
Spitfire: The level-headed leader of the Wonderbolts. It’s a wonder how she stays sane with all of them, but she manages. With the help of her sister and Soarin’, she gets the team together to train and be the best they can.
 
Soarin’: The light hearted little dude who just loves pie. He’s been Spitfire’s best friend since childhood, and rumored ex-coltfriend. The breakup was a friendly one though, and they managed to remain friends. He’s extremely loyal and kind, and gives great advice.
