Name: Rainbow Flash
Nicknames: Blizzard, Blizz
Parents: Rainbow Dash, Flash Sentry
Siblings: Sunny Daze, Daffidazey
Special Talent: like his mother, he's great at flying and even earned his cutiemark in a race like she did. But he's not sure if flying is his passion at all, he can't feel the "spark" in it.

Quiet and submissive, Blizz is almost a shadow of its former self. He's not of many friends and prefers to spend time alone, perhaps reading a book or listening to music. He likes simple things.

His friend Lionheart is the one who mostly takes him out of his comfort zone, even if it's to go shopping for candy at Sugarcube Corner. Being the total opposite of him and similar to how he used to be, he has a warm and friendly side that shares with him. Giving Lionheart the title of being one of the few who have managed to make him smile.

With his parents is a distant relationship, he usually spends more time with his grandparents or his uncle Blaze. On the other hand, he has a complicated relationship with his sisters, he loves them and cares about them, but they are not the best siblings in the world.
