Lucina of Fire Emblem is Chrom's daughter, and the future princess of Ylisse.
Although her present infant self is born during the two-year period of peace, her future self appears at the beginning of the game under the guise of Marth. She doesn't reveal her identity until Carrion Island, where she saves Chrom from a Risen assassin. She is haunted by her memories of Grima; she saw him once in her time, and he has appeared in her dreams ever since. Lucina is voiced by Yū Kobayashi in Japanese and Laura Bailey in English, though she is uncredited for this role. She also appears as an unlockable playable character in Super Smash Bros. for Nintendo 3DS and Super Smash Bros. for Wii U.
