Prince Blueblood is a unicorn who appears in Canterlot. He starts out as the object of Rarity's affections, but once they meet turns out to not be what she was expecting. "Blueblood" is an English idiom for "nobility", or being of noble birth or descent. It has been recorded since 1834 and comes from the Spanish words sangre azul, describing Spanish royal families said to be descendants of the Visigoths.
