Lucina

Lucina is one of the 3 main characters of Fire Emblem Awakening. She is the daughter of Chrom who was gifted with the mark of Naga on her left eye. Like in the present timeline, future Lucina was born to Chrom and his wife after the Ylisse-Plegia War. After Chrom's death at the hands of Grima, Lucina inherited the Falchion and attempted to fight Grima. She never learned who killed her father, however, her only clue was that her father's murderer was someone close to him. At some point, her mother was also killed in battle. With the world on the brink of destruction, Lucina was down to only her closest allies, the other children of the Shepherds (and in the game, her younger sibling, depending on who her mother was). Eventually, she traveled to the past and she arrived shortly after Chrom just recruited Robin albeit she goes in the guise of "Marth" for a temporary disguise.

Why She Rocks

 * 1) The personality that she typically has consisted of being a strong-willed, pragmatic, and serious soul who wants to defy fate to alter the dark future she came from and has a sense of justice. Because of that, she ends up being the leader for the survivor children of the Shepherds.
 * 2) Even if her leadership skills are good while also caring for the comrades deeply, she never really gives herself any credit. This makes her humble.
 * 3) Her main motivations come from her love for her parents (mainly Chrom) and this would allow her to do whatever it takes to keep him alive even if it means going against her wish for no needless deaths. With that said, she's obedient to her father and puts her trust in his judgments, showing a strong bond of trust with him.
 * 4) Due to the deaths that caused a large kill count, she dislikes any form of death, even "noble" ones since this can be seen as a good reason why she thinks that her backstory can be justified for this.
 * 5) She shares a great resemblance to her ancestor Marth from her actions when helping others to even speaking in a formal and polite manner. Of course, she and her ancestor are different from each other which does not make her a carbon copy of Marth.
 * 6) She has a reason as to why she wants to spend as much time as she can with her parents just because of her childhood as it's a confirmation of what she desires. Once the world is saved, she doesn't wish to get in the way of them tending to their present daughter, despite the assurances from them both that even though she's from a different timeline, she is still their daughter and that they love her equally.
 * 7) She's really pretty and cute so what else is there. Well, it takes more than a pretty face to be likable and she does it well. In battle, she is courageous yet she's cute outside out battle
 * 8) Even for a serious character she does have her moments where she has a light and unintentionally goofy side around the ones she is close to (it mainly works with a parent and sibling). Her supports can actually prove it.
 * 9) Has a deep backstory. She came from a terrible future as her bio states.
 * 10) In the game she came from, she is first seen as a somewhat familiar yet suspicious figure in the form of Marth. Not only does it pays homage to the latter, but it also brings upon wonder and drama on who is this figure. Everything starts to change as this Marth disguise was actually a girl being the true identity in the form of Lucina (her mask got sliced off by an assassin). It even went to the point where she started crying after showing Chrom the Brand of the Exalt. As a result, she didn't want to fight as "Marth", but rather herself.
 * 11) At one point, she did try to kill Robin (the avatar character) to eliminate what happened to Chrom who got killed in her future with the latter choosing to accept her judgment or not (Chrom stopped her anyway). However, if you let her marry Robin, she will not go through with it when Robin makes his last request for her to find someone to keep her happy. If her mom happens to be the female Robin, she cannot bring herself to kill her own mother.
 * 12) Her personal exclusive weapon that she wields is the Parallel Falchion. It trumps Chrom's version of the Falchion with 7 more Might and 5 more Critical. It also has the ability to heal her for 20 HP if used as an item, so she never needs Vulneraries or Concoctions so long as she is in a sword-wielding class.
 * 13) If she is not paired with someone, she whispers to her infant self that she will live a better life than she did and promptly leaves, leaving no trace of what happens to her after.
 * 14) *On the other hand, she can have an ending where she's paired with someone and also get a good ending like with Robin, Inigo, Brady, Gerome, and Laurent.

Bad Qualities

 * 1) Like her dad, she has a habit of breaking things when practicing.
 * 2) Has a paranoid streak.
 * 3) Has a bizarre taste of fashion, but to be fair, this makes Lucina be very beautiful and pretty.
 * 4) Has a rather dry sense of humor.

Trivia

 * She is named after the Roman Goddess of childbirth. In ancient Roman religion and myth, Lucina (the Roman Goddess) safeguarded the lives of women in labor. Lucina was also an epithet for Juno. The name was generally taken to mean "she who brings children into the light" which may relate to how she (the character) leads the other second-generation characters back into the past to save the world.
 * 1) **There are also several moths and butterflies that contain the word Lucina in their species names such as Dactyloceras Lucina, Hypatopa Lucina, and Hamearis Lucina. These may be the origin of Lucina's butterfly motifs. They could be a reference to "The Butterfly Effect" as it's a time travel theory in which a small change in one state of a deterministic nonlinear system.
 * She's the only child character (not literally a child, but still) who must be recruited for story purposes
 * She's the only child in Awakening with fixed hair color and cannot inherit the hair color of her non-determinate parent.
 * Her birthday is on the same day as the first Fire Emblem game (Shadow Dragon and the Blade of Light)
 * If Lucina and Owain achieve an S-support, they will gain the title "Companion", on their character cards instead of "Husband/Wife" to prevent implications of incest. The title is also used if she achieves an S-support with Morgan if Inigo or Brady is his father (and Chrom is Inigo or Brady's father).
 * If Lucina is the daughter of Robin, Lucina will have the most amount of class options out of all characters in the game with a total of 35 (34 without Bride).
 * Her confession image is unique in that the background does not change to a bubbly pattern variant seen in most other confessions.
 * If Female Robin marries Chrom, Lucina will have both the Exalted Blood and Fell Dragon Blood. Lucina is one of four children who can possibly have this trait, the other 3 being both Morgans and Owain.
 * Although Lucina can use Counter in Super Smash Bros. for Nintendo 3DS and Wii U, it is impossible for her to learn it in Awakening since it is a male-exclusive skill and because Chrom cannot reclass into the Fighter classes. Even if he could learn it, Lucina will never inherit it since Chrom always passes Aether down to her.
 * Lucina is the first unlockable character in the Super Smash Bros. series to be female, being unlockable in both versions of Super Smash Bros. for Nintendo 3DS and Wii U; all of the other unlockable characters, in addition to the ones from the past three games, are either male or gender-neutral (referring to Pokémon). Also, the first clone/Echo character to be a female before Daisy became an Echo of Peach.
 * Lucina is one of the few units whose status screen portrait changes at some point of the game, a trait she shares with Marth, Alm, Celica, Ike, Volke, Sothe, Julia, Micaiah, and Kris. Her change happens when her mask is broken before Chapter 6. Unlike most examples, Lucina's portrait changes when she's still an NPC.
 * Lucina's mask holds great symbolism. Butterflies have been known to symbolize Hope, Joy, and New Beginnings: all of which are aspects for which Lucina and the other second-generation characters fight. It also symbolizes the element of time, which is reflected through their time traveling in-game.
 * 1) *In the Drama CD and the Manga adaptation, she intended to use a pair of massive glasses.
 * One of the two items that the player can receive from Lucina in Fates is the Bear Hat. She refers to it as being totally cute which is a joke on Lucina's terrible fashion sense. The hat itself is a reference to the final Drama CD for Awakening.
 * Her tiara was a gift from her mother.
 * Her "Masked Marth" variation is the only character in the game with no innate passive skills whatsoever.
 * Is heterochromatic with her left eye being brighter than her right one. Most likely, it's because of the brand than of an actual genetic change, but it was never clarified.
