Originally born in a small unknown village, Fizzle Pop Berry Twist (commonly known as Commander Tempest Shadow) is a headstrong and stubborn mare.
Due to an accident with an Ursa Minor as a filly her horn was shattered and exploded on impact, causing an array of lifelong injuries. The heat from the blast had burned her right eye shut and covered her in scars, as well as majorly blinding her left eye and causing her lifelong severe back and leg pains.
Despite her illnesses she’s just as much as the kick-ass mare she was in the movie, currently being a simple traveler along Equestria and one of Twilight’s closest friends.
