<P> Princess Cadance and Shining Armor are Twilight Sparkle's older sister - in - law and brother, respectively, who both debuted in the season two finale "A Canterlot Wedding". Cadance, a kindhearted alicorn who is fully named Princess Mi Amore Cadenza, is Princess Celestia's adopted niece and Twilight's childhood "foal - sitter" (babysitter); according to her backstory presented in Twilight Sparkle and the Crystal Heart Spell, Cadance is a former pegasus who turned into an alicorn after reversing an evil sorceress's love - stealing spell . She marries the unicorn Shining Armor, who is the captain of Canterlot's royal guard and has a close relationship with his sister, for which he is nicknamed her "Big Brother Best Friend Forever" (B.B.B.F.F.). In the third - season premiere, Celestia appoints Shining Armor and Cadance to rule the Crystal Empire, an "ancient city" that Cadance protects using the power of love so that their subjects, the shimmering coated "crystal ponies", may magically project their feelings of hope and love across Equestria . In the season six premiere "The Crystalling", Cadance gives birth to an alicorn filly named Flurry Heart (voiced by Tabitha St. Germain). </P> <Ul> <Li> Voiced by Kelly Sheridan </Li> </Ul> <Li> Voiced by Kelly Sheridan </Li> <P> Starlight Glimmer is a unicorn who debuted in the season five premiere "The Cutie Map". Initially appearing as a "perfectly pleasant - looking unicorn", Starlight proves to be a sinister figure who wishes to build a "perfectly equal society" by using her magic to remove other ponies' cutie marks; she cites her reasons as believing that differing degrees of ability cause disharmony between friends, stemming from her estrangement from her childhood friend Sunburst (voiced by Ian Hanlin) after he earns his cutie mark before her . She later appears in the season finale "The Cutie Re-Mark" to take revenge against the Mane Six by traveling to the past and preventing their friendship before it starts . After realizing the catastrophic changes this causes in the present, Starlight is convinced to change her ways and make new friends . She appears in season six as Twilight's pupil who studies friendship alongside the Mane Six in Ponyville, a role she graduates from in the season seven episode "Celestial Advice". According to Miller, Starlight's design was chosen to parallel her role as a "proto - Twilight character". Her original name during production was "Aurora Glimmer", which was changed due to the Walt Disney Company's trademark of the character name "Aurora". </P>
