Lucina (ルキナ, Lucina) is a character from the Fire Emblem series tactical role-playing games, introduced in its thirteenth installment Fire Emblem Awakening as one of its three main characters. She is a distant descendant of Marth, and is the daughter of fellow protagonist Chrom.
Lucina is a princess of the kingdom of Ylisse, the successor state to the now-ancient kingdom of Archanea, and is Chrom's daughter. She bears the holy bloodline of Ylisse's rulers, the exalts, who carry the power of the legendary dragon Naga and her holy gifts to humanity: the Fire Emblem and the blade Falchion; this power is signified by the presence of a distinctive Brand on their bodies, with Lucina's being located in the iris of her left eye.
The adult Lucina the game primarily features is a time-traveller from an alternate future, who travels back to the current timeline in Fire Emblem Awakening due to the fell dragon Grima and his legions of Risen zombies bringing her own world to ruin. Desperate to reverse this unfortunate event, she and other future children of Chrom's allies, the Shepherds, travel back in time to prevent the revival of Grima in Chrom's timeline and change the future. When she travels back in time, she initially hides her identity by tying her hair back and wearing a distinctive mask given to her by Gerome, one of her allies from the future, and adopting the name "Marth" from her famous ancestor. She runs into Chrom and the Shepherds, saving her aunt Lissa from the first of the Risen on one occasion and later dueling Chrom in Arena Ferox. Her disguise is ruined during an assassination attempt on her aunt Emmeryn while defending Chrom, causing her to disappear, only to reappear two years later, again defending Chrom from an assassination. She is accidentally revealed to be a woman after an unexpected assassin appears and cuts her mask off before being killed by Chrom. Later, she confirms that she is his daughter by allowing him to see the Brand of the Exalt in her eye, just like his newborn daughter. Lucina then joins the Shepherds to assist them in a new war.
In game, Lucina starts out as the Lord class by default, inheriting the class from Chrom. As she is pivotal to the story, she is the only child unit whose recruitment is forced, and one of the few units that will not be permanently lost, even in Classic mode. Like Chrom, her weapon of choice is Falchion, but her version of the famed sword is the Parallel Falchion brought back from her future. Unlike Chrom's version, it is more powerful and can be used to self-heal, whereas Chrom's Falchion is initially weaker with its power sealed away and must be upgraded before the final battle to become stronger than Lucina's. Lucina can either be a potential wife for male Robin or female Robin's daughter if the latter is married to Chrom. There is also a variety of potential affine relationships between Robin and Lucina which are not acknowledged in game.
Alongside international success of Fire Emblem Awakening, Lucina has become one of the most popular Fire Emblem characters worldwide outside of Super Smash Bros. Since her debut, she has appeared as a guest character in Code Name: S.T.E.A.M., Fire Emblem Fates, and Fire Emblem Echoes: Shadows of Valentia, in each case summoned in-game using her amiibo. She appeared with Chrom and fellow smasher Ryu in Project X Zone 2, a crossover strategy game featuring characters from Bandai Namco, Capcom, Sega, and Nintendo. Several outfit variations of Lucina are also featured in the crossover game Fire Emblem Heroes, and she is also playable in Fire Emblem Warriors.

Lucina appears as a newcomer in Super Smash Bros. 4. She is a clone of Marth, though she is shorter, and the strength of her blade is balanced throughout, rather than stronger at the tip like Marth's blade.
Appropriately, she is unlockable by completing Classic Mode with Marth on any difficulty in the 3DS version. She is unlockable by completing Classic Mode with any character on 5.5 Intensity or higher in the Wii U version.
Of note is that she was originally planned to be an alternate costume of Marth, but was given her own character slot later in development due to "the characteristics of their attacks being different".
On the current tier list for SSB4, Lucina is ranked 14th out of 55 characters, placing her three spots below Marth. While her Parallel Falchion grants her a good disjointed reach, she still suffers from high endlag in her moves, much like Marth. She also lacks a tipper, giving her a generally weaker neutral game than Marth, though this still gives her some slight advantages over Marth, as the consistent damage from her sword allows her to afford being closer to opponents, all while still delivering decent damage and knockback. As a whole, the few strengths she possesses over Marth are fairly minor, and although she has been buffed to similar degrees by game updates, she is generally seen as an inferior version of him, resulting in lower tournament representation and results in comparison.

Lucina returns in Super Smash Bros. Ultimate as an unlockable Echo Fighter of Marth. She retains her primary difference setting her apart from Marth, that being her lack of sweetspots and sourspots on the Parallel Falchion, but has been subtly recloned in other aspects, such as no longer being shorter than Marth.
Lucina received a mix of buffs and nerfs in the transition from SSB4, but has been overall buffed. While she received some direct nerfs, mostly shared with Marth, she benefits greatly from universal changes to the point of counterbalancing those nerfs, as the faster pace of Ultimate allows her to more easily take advantage of her balanced damage output compared to Marth's weaker sourspots and less forgiving tipper sweetspots. As such, Lucina has very strong representation and results in tournaments, with many players considering her a viable top- or high-tier character, as well as the best swordfighter in the game.
