Enigmatic Blade

"I challenge my fate!"

A masked swordsman who claims to be the Hero-King of ages long past. He wields another Falchion, a blade once thought unique, and appears during Chrom's hour of need. Whether he's truly the Hero-King or simply an impersonator is a mystery. She is actually Chrom's daughter from the future, Lucina. A kind and just princess who has made it her duty to save the world. In her era, the world was devastated by the reawakened Grima and, by Naga's guidance, she traveled to the past to stop Grima. She loves her father and would do anything to keep him safe. The least likely to get a joke. Her birthday is April 20th.

She's every bit as competent and determined as her father, and can also be one of the most powerful units in the game like him if bred/trained properly. Among the future children, she's considered the most capable.

Lucina appears as a playable character in Super Smash Bros. for Nintendo 3DS and Wii U and Super Smash Bros. Ultimate, the fourth Lord (after Marth, Ike, and Roy) in the series to be playable in Smash, and is also a playable unit in Codename STEAM and Fire Emblem Fates via her Smash Bros. amiibo.

Class: Lord (default), Great Lord (Future Past DLC)

Voiced by: Yuu Kobayashi (Japanese), Laura Bailey (English, Awakening, Smash, Codename: STEAM, Heroes (original version)), Alexis Tipton (English, Heroes (all variants of Lucina), Warriors)

---

A-K

• Action Mom: To Morgan, if she marries the male Avatar.
• Alternate Self: Uniquely among the Second Generation, she has actually been born in the main timeline by the time she shows up, her infant self left back at Ylisse Castle being wet-nursed (or in the care of her village maiden mother if none of the Shepherd candidates marry Chrom); both versions have a Brand of the Exalt in their left eyes, which is how Chrom realizes who she is during The Reveal. While it's not heavily telegraphed, a lot of her actions prior to Chapter 13 make more sense in hindsight knowing this.
• Ancestral Weapon: The Parallel Falchion, inherited to her from her father Chrom.
• Armor-Piercing Attack: The second hit of Aether. To differ her and Chrom, Lucina's leap up skills to Aether in Fire Emblem Heroes are New Moon and Luna.
• Animal Motif: Butterflies, by way of representation in the animated intro, shape of the mask, and shape of the shield as a Great Lord. Lucina also received a Ljósálfheimr-themed Resplendent outfit in Heroes, keeping the butterfly motif intact. In many cultures, butterflies are symbols of change for the better. May also be a reference to the Butterfly of Doom.
• Aren't You Going to Ravish Me?: Lucina's supports with a female Avatar who's not her mother first see her warn the Avatar against trying to seduce her father. When the Avatar assures her that she isn't attracted to him like that, Lucina becomes insulted and demands that the Avatar admit what a wonderful, attractive man he is and start falling in love with him immediately!
• Badass Adorable: Lucina brings this trope to a whole new level in a series that was already packed with this particular type of badass. In the battlefield, she's tough as they come. Outside of it, though, she totally gets the "D'AAAW!" effect.
• Badass Cape: Ever billowing in Dramatic Wind.
• Bamboo Technology: The cover of the game's soundtrack CD shows Lucina wearing a pair of large flowers like "headphones", with a vine as the "cord".
• Battle Couple: Can be paired with male Avatar and any male second generation character. Her fastest support is with Laurent, though.
• Bishōnen: Artwork of a maskless "Marth" in the pre-order artbook reveals he is quite the pretty boy, not unlike the original Marth.
• Bifauxnen: As it turns out, it's justified that he looks like a girl because she is a girl.
• Big Sister Instinct: Aside from her actual sibling, Lucina has shades of this towards many of the other children, but it's especially pronounced towards Cynthia and Nah.
• Birds of a Feather:
  • With the male Avatar. Tiki describes both as leaders capable of inspiring trust and love among their comrades.
  • Lucina believes she and Gerome are similar in that they both only shine on the battlefield, but Gerome reassures her that she is also a capable leader, unlike him.
• Birthmark of Destiny: The Mark of Naga in her left eye, which allows Chrom to realise who she is after having seen it in her infant counterpart.
• Black Knight: Her "Marth" persona has shades of this trope.
• Boyish Short Hair: Subverted. When she poses as "Marth", her hair appears to be shorter. When her mask gets broken in Chapter 6, her hair comes loose and is let down, revealing that it goes down to the middle of her back.
• Breakout Character:
  • Outside of her home game, she has made appearances as a playable character in Super Smash Bros. for Wii U and 3DS, the fourth Lord in the series to be playable in Smash, and in Codename STEAM and Fire Emblem Fates via her Smash amiibo, and is the first Fire Emblem character to get a figma action figure. At this point, she's overshadowed her own father, largely stemming from his infamous exclusion from Super Smash Bros for 3ds and Wii U, and has essentially become the Rosalina of Fire Emblem. Eventually, it was announced that she will be included in Project × Zone 2, though fortunately, Chrom is included too.
  • In Fire Emblem Heroes, within six months of the release, you could possibly field a team of four distinct Lucinas — so, basically, a full team of Lucinas: Default Lucina, Spring Bunny Lucina, Masked "Marth" Lucina, and Brave Lucina. What makes it even more impressive is that two of those (Masked Lucina and Brave Lucina) can be obtained by players without having to go through the gacha system, making her also the first character to be available "for free" in two different versions. In addition, Lucina utterly curb-stomped Sharena, Eirika and Ephraim during the first Voting Gauntlet, winning it all and cementing her popularity.
• Broken Bird: As "Marth". She keeps her distance from the Shepherds and doesn't show much emotion at first unless things start to look like they're going the same way as in her timeline. When she reveals herself as Chrom's daughter, she finally breaks down and expresses her sadness and pain over losing him; assuming one of the Shepherds is her mother, she'll break down in her arms as well after explaining she comes from the future. Even once she's free to express her emotions, by default she is very stoic and serious even when faced with a rather silly situation. Nevertheless, escaping from the Bad Future allows her to heal somewhat via experiencing Mundane Luxuries and getting to spend time with her parents again.
• But Now I Must Go: In her non-paired ending, she whispers the words "Yours will be a happy future" to her infant self and then simply disappears. No one knows what happened to her after that.
• The Comically Serious: A complete badass on the battlefield, but an utterly adorably humorless dork off of it. She's so used to being completely serious that she generally takes pretty much everything completely seriously, like her epic struggle to buy a wooden figurine of one of her parents in the DLC chapter "Hot Spring Scramble", or when Owain tells her that by renaming Falchion to "Pointy Demonspanker", she's insulted the spirit that has dwelled within the blade since it was first named millennia ago (something he made up on the spot to get her to change the name back without making fun of her), her reaction is horror, and her voice clip is "No... oh gods NO!", which is usually reserved for whenever history seems to be heading back towards its original course. She's aware of her own stiffness and asks several of the wackier second-generation characters for help dealing with it in her supports.
• The Champion: Winds up as Basilio's in Chapter 4, in a literal sense. Once she reveals her true identity, Lucina seems to quickly become Chrom's champion, dedicating her everything to his cause and prioritizing her father's safety above all else.
• Char Clone: A mysterious, skilled, masked fighter, and even competes against Chrom at one point.
• Compressed Hair: Word of God says she tucks the longer layer of hair under the shorter, as depicted by the game's artist here.
• Cool Big Sis: To her possible siblings, but especially towards Cynthia (whether they're sisters or not) as shown in the Harvest Scramble DLC.
• Cool Mask: One shaped like a butterfly, which she uses to hide her identity in the first few chapters of the game.
• Cool Sword: Wields the Falchion as well, initially thought to be a separate sword to the one Chrom uses — which stumps everyone, since it's supposed to be one of a kind. It really is, as "Marth's" Falchion is actually the same sword, brought back from the future.
• Childhood Friend Romance: With all the second generation boys, though the biggest vibes are with Gerome, as she explicitly tells him that he's her "most stalwart companion from childhood".
• Critical Status Buff: Her Defiant Speed skills in Fire Emblem Heroes provide her with boosts to her speed stat when her HP drops below half. Her amiibo in Fates has a similar skill called "Awakening".
• Daddy's Girl: Very much so. She Hero Worships Chrom and desires to know about and spend as much time with him as possible. Her love for her mother is quite something as well — it may be the only thing that prevents her from killing Robin if she is her mother during Chapter 21.
• Deadpan Snarker: She has her moments, such as when her true gender is revealed:
  Chrom: Wait. You're... you're a woman?
  Lucina: And quite the actress, too. Honestly, I'm surprised you didn't figure it out until just now.
• Deuteragonist: She goes through time to change her fate, and makes many key attempts to alter her future.
• Developers' Desired Date: For Male Robin. They get a fair amount of Ship Tease, and her assassination attempt changes if they're married.
• Developer's Foresight: A certain cutscene after Chapter 21 changes should Lucina be either married to the male Avatar or if the female Avatar is her mother.
• Dude Magnet: She's able to marry the Avatar and any second generation male, plus Inigo and Gerome both claim to have always been in love with her. Even Basilio is attracted to her. This isn't too surprising, though, considering who her father is.
• Exotic Eye Designs: Her Mark of Naga is in her left eye. It's what makes Chrom realize that she is his daughter from the future, as she has the Mark of Naga in that exact same spot.
• Expy:
  • A gender-flipped version of Future Trunks. Both came from a Bad Future where almost all the heroes were killed. Despite failing to stop the awakening of the villain, they definitely change the tragic future in the end. The main difference between them is that Lucina can wind up sharing her role with the other Second Generation characters.
  • A princess who takes on a face-concealing male alter ego after her kingdom is conquered by the forces of evil, in a plot that revolves heavily around time travel and collecting magical orbs to awaken a legendary sword whose purpose is to seal away said evil? What other Nintendo game have we seen this in before?
• Flower Motifs: In the Bad Future, flowers are all but extinct. In Lucina's S support with a male Avatar, he gives her a bouquet of flowers, a symbol of their promise to never surrender to fate, the main theme of the game.
• Foreshadowing: When "Marth" matches Chrom's swordplay blow-for-blow during their arena cutscene, as well as having the exact same one-of-a-kind sword, it's clear that something's up.
  Chrom: Tell me, who taught you to fight like that?
  "Marth": My father!
• Foolish Sibling, Responsible Sibling: Lucina will typically be the responsible sibling to any of her prospective siblings' foolish sibling. It's most pronounced, however, with Cynthia, Inigo, and Male Morgan.
• Fragile Speedster: If Chrom marries Maribelle, Lucina's Defense will take a hit, although her Speed will remain fairly high. The boost she receives in Magic and Resistance, however, does make reclassing to a Squishy Wizard a viable option, plus being reclassed into a War Cleric or Dark Knight will give her self-healing skills like Renewal or Lifetaker.
• Freaky Is Cool: She is very accepting of the odd personalities of her comrades and admits to finding Owain's strange personality and speech pattern charming and attractive because of how unusual it is.
• Futile Hand Reach: Her death/defeat animation. Lucina weakly reaches out for the sky before collapsing.
• Future Badass: Who would have thought that adorable baby girl would grow into such a tough-as-nails badass?
• Gender Flip: Coming full circle, the DLC version of Marth◊ in Awakening is a gender-flipped version of Lucina model-wise, with the same clothes and tiara as well as the shorter hairstyle that she used when in disguise. He might even be using the same face as Lucina, making his model nothing more than a combination of Lucina's disguised and unmasked looks.
• Giver of Lame Names: In her supports with Owain, she decides to change Falchion's name to "Pointy Demonspanker." Owain convinces her to change it back.
• Glass Cannon: If Chrom marries Sully or Olivia. The two offer Lucina several offense-oriented skills (like Astra), but fewer defensive options. She can possibly inherit Galeforce from Olivia as well.
• Guilt Complex: Her supports with Laurent and Yarne reveal that she has a tendency to blame herself for everything that goes wrong, regardless of whether or not it is her fault.
• Healing Factor: When wielding the Falchion in Fire Emblem Heroes, Lucina is healed 10 HP on every third turn. If refined, the Falchion ups that healing to every second turn.
• Heal Thyself: She can use the Parallel Falchion to restore 20 HP.
• Heroic BSoD: Goes into one when the main game catches up with the interlude.
• Hero of Another Story: The Future Past DLCs, despite intervention from Chrom and the Avatar, ultimately features Lucina as the central character.
• Hidden Depths: Surprisingly, when in private she is somewhat more bumbling than the average Action Hero, if her supports are anything to go with.
• Hidden Heart of Gold: While posing as Marth, she is a bit standoffish. Once she reveals her identity to Chrom, she mellows out immensely.
• Humanizing Tears: She initially acts aloof towards Chrom, becoming slightly more personable after the Gender Reveal while still keeping her distance. This completely changes after she reveals who she is, after which she comes crying into her father's arms. In the Hot Spring Scramble DLC, she admits she probably would have done this the moment they met if she didn't have a mask to hide behind.
• Humble Hero: Despite her righteous and kind personality and skills as a swordswoman, Lucina never gives herself any credit and is constantly fretting over if she can live up to Marth's name.
• Important Hair Accessory: Her signature gold diadem. It even has dragons engraved on it! The CD dramas say she got it from her mother, no matter who she is.
• Impossibly Tacky Clothes: The dresses she keeps picking out for her mother in her supports, although off screen, are implied to be this. Later, something similar happens with Tiki in the Harvest Scramble DLC. Her fashion sense is horrible, so if you ever see her wearing something decent, it's because someone else chose it for her.
• In Love with the Mark: Comes back in time to save the world from the future that befell her own time, and to kill the person who murders her father. She never actually learns who it is, however, only aware that they're someone close to Chrom. As noted in the beginning's cinematics, Robin is the one who offs Chrom. Despite this, Lucina is a romance option for a male Robin, and if they are married when Chapter 21 is completed, there will be a heart-rending cutscene where Lucina can't bring herself to kill Robin because of how much she loves him, despite Robin even potentially pleading with her to go through with it.
• Irony: If she marries the Male Avatar. She went back in time to stop Grima, only to fall in love with his vessel.
• Jack of All Stats: Lucina, by herself, is naturally quite balanced and flexible, so who her mother is will have a big say in what she can become.
• Kid from the Future: The first of many in this game.
  • Not only that, but like everyone else, she can get her own kid from the future (Morgan) if she marries the Avatar.
• Kissing Cousins: She can marry Owain, who is Lissa's son. This is narrowly averted in the English version, where they are listed as Companions instead of Husband and Wife; their S-ranked support is more platonic in nature because of it. However, their Event conversations are still as romantic as any other married couples' conversations. If Brady or Inigo is her brother and is paired with a female Avatar, she can also end up marrying her nephew, and unlike in the various cases of cousins marrying, the English version also lists this relationship as Husband/Wife.
• Knight in Shining Armor: A brave, mysterious hero who protects the helpless innocents and saves the day. Even Lissa is briefly swooned.
• The Knights Who Say "Squee!": Lucina places her father high on a pedestal and idolizes everything about him. Having lost him at a young age, Lucina is all too eager to learn everything she can about Chrom.

L-Z

• Lady of War: Her battle animations are all graceful, quick, and powerful.
• Lame Pun Reaction: During her support with a non-sibling Morgan, she comments on how the ties between their father and mother are so close that it surprises her that they never ""tied" the knot". Morgan recognizes that it's a bad pun, but appreciates the fact that it got her to at least try making a joke.
• The Leader: All of the second-generation Shepherds defer to Lucina.
• Leitmotif: "You may call me Marth."
• Life Drain: The first hit of Aether. Her Brave variant in Heroes learns Daylight and Sol as her lead up skills to Aether, which provide this.
• Lightning Bruiser:
  • If Chrom marries the Avatar, Lucina inherits the Avatar's ridiculous class and skill selection, as well as a variety of maximum stat modifiers that can easily boost her strengths and offset her weaknesses.
  • Lucina will also end up as this if Chrom marries Sumia, thanks to the latter's variety of great offensive and defensive skills for any challenge, a massive increase to her Skill and Speed stats in exchange for a medium drop in Defense that she can offset with her inherited defensive skills, and the possibility of getting the very sought-after skill Galeforce from Dark Flier much faster in comparison to other potential mothers who can pass off the skill (due to the fact that Sumia is the only one who starts off in the Pegasus Knight line, meaning she can promote into Dark Flier as soon as she reaches level 10, whereas the others must reclass into the line first).
• Like Father, Like Son: Her experience up quote implies that she has inherited her father's penchant for breaking things when practicing.
• Love Confession:
  I love you. And no matter what the future holds, I'm going to cherish every moment.
• Love Hurts: Played with. If she marries the Avatar, then this is very definitely the case after Chapter 21, where she discovers that he is the vessel of Grima who is going to kill her father and destroy the world. She eventually decides that even so, she can't bring herself to kill him, as she loves him too much (which also happens if the Female Avatar is her mother). In the end, though, it all turns out alright.
• Luke, I Am Your Father: If her mother is the Avatar, then this was Grima to Lucina all along.
• Luke, You Are My Father: She's Chrom's daughter. The blue hair is not coincidental. She accidentally outs herself in Chapter 13 by shouting "Father, no!" when Chrom gets ambushed by a Risen Assassin.
• Lunacy: A moon appears on screen when she uses New Moon or Luna in Fire Emblem Heroes.
• Master of None:
  • Compared to the other options, if Chrom marries the Village Maiden. Her growths are greatly hurt by not having a playable mother's growths stacked onto her own, causing her to drop off heavily as the game goes on.
  • A Magic Boon Avatar mother often results in this as well. Even if the Avatar has their best stat being Magic, Lucina's Magic growth will only cap at 36%, which is barely enough for her to even consider wanting to invest in a magic class. She'll be still decent at fighting, but she'll lag behind other child units by comparison.
• Meaningful Name: A twofold one. Lucina is part of the name of a butterfly, specifically the Hamearis Lucina, reflecting her butterfly motif. It's also the name of a Roman Goddess of Childbirth, and could be taken to mean "she who brings children into the light" in that context, which reflects on her role as the first of the Second Generation units in Awakening, and the one who introduces the concept to the player.
• Mind Screw: Being a time traveler and, on top of that, in a time when she's been born already (although still a baby), we get some of this in her support conversations with her possible mothers.
• Mirror Boss: "Marth" serves as this during Chapter 4. Unlike most bosses in the game, Marth can move around the map, just like basic enemies and the player's units can. Marth is also of the same Lord class as Chrom, and uses a stronger version of his Falchion to boot.
• Moveset Clone: "Marth" in Fire Emblem Heroes has the exact same stats as a neutral Lucina, but lacks any skills other than her weapon.
• Mundane Luxury: Surprisingly, given her normally very stoic and serious demeanor, her support conversations with her mother and the Scramble DLCs actually have her display a rather excitable side brimming with child-like enthusiasm in regards to small amusements such as dresses or feasts. She justifies this in her supports with her mother, saying that during the harsh times of the future, she often dreamt of such simple pleasures.
• Mundane Utility: She doesn't do it herself, but she gets REALLY mad during her B support with her sibling when she catches them using the Falchion to cut fruit!
• My Sister Is Off-Limits: Lucina's supports with the Female Avatar is a variation of this if the Avatar and Chrom are not married. Lucina is paranoid at how close the two are and is convinced that the Avatar is trying to seduce Chrom.
• Mysterious Protector: "Marth" protects both Lissa and Chrom on separate occasions, both times declining to reveal her true identity.
• Nice Girl: Lucina helps around camp on her spare time, is very supportive of her friends, and is always trying to improve herself as a leader.
• Nice Job Breaking It, Hero: As it turns out, when she first used Naga's Time Travel spell, the future Avatar, who, unlike the present one, did accept their fate to become Grima, followed Lucina back into the past, proceeding to revive Validar after his botched attempt to assassinate Emmeryn, and then just bide their time until the time came for Grima's revival, upon which they offered themselves to Grima in the present Avatar's place. Of course, in Lucina's defense, she had no way of knowing that would happen.
  • Also inverted; her very time-traveling which allowed Future Grima to come back to ensure his own resurrection also gave them an amnesiac Avatar, making them more inclined to forge deeper relations with them allies and refuse their role as Grima's vessel. This works against Grima in the worst possible way, as the Avatar is the only one who can kill him for good.
• No Social Skills: Downplayed. She's capable enough with people, but seems to lack a concept of normalcy. For instance, she doesn't quite understand why people would see anything obscene about mixed bathing in the Hot Spring Scramble DLC.
• Not So Above It All: Her C support with her possible siblings has her scolding them for making a fuss over a bug, but when she sees the bug herself, Lucina screams hysterically, too.
• Not So Stoic: When she breaks down crying in her father's arms.
  • Also, if the Avatar is either her husband or her mother, she actually breaks down into tears that she can't bring herself to kill them, because, despite being the cause of Chrom's demise in the bad future, she still loves them.
• One-Man Army: Well, "One-WOMAN army", in actuality. Lucina is easily one of the most powerful characters in the entire game.
• Opaque Nerd Glasses: According to a Nintendo Dream comic, this is one of the disguises Lucina was considering using before settling for the butterfly mask.
• The Paladin: In the grand scheme of things, this trope perfectly defines what "Marth" stands for.
  • Bonus points for being able to eventually reclass into a Paladin due to her heritage from Chrom.
• Paper-Thin Disguise: A subversion: "Marth" is very obviously a woman trying to disguise her voice, but her actual identity as Chrom's daughter is very well kept. She lampshades this when her mask breaks and Chrom discovers her gender.
  Chrom: Wait, you're-you're a woman?
  Lucina: And quite the actress, too. Honestly, I'm surprised you didn't figure it out until just now.
• Perpetual Frowner: According to Inigo, but not quite as much when compared to Noire, Severa, or Gerome.
• Pre-Mortem One-Liner:
  "I challenge my fate!"
  "You will not stop me!"
  "I say when it ends!"
  "Hope will never die!"
  "I will never give up!"
  "Our bonds give me strength!"
• Poor Communication Kills: Played for laughs in some of the paralogues involving her potential siblings. Chrom would remark how Lucina neglected to mention she had a brother/sister when confirming the other child's identity.
• Properly Paranoid: Knowing what the future holds, Lucina will try to keep Basilio from fighting Walhart, and even tries to kill the Avatar in a desperate attempt to protect the world.
• Rank Scales with Asskicking: She is regarded as the leader of the second generation characters, and can match blows with the Shepherds' overall leader Chrom.
• Religious and Mythological Theme Naming: Both Geirskögul and Thögn are named for Valkyries from Norse Mythology.
• Requisite Royal Regalia: The signature tiara.
• Royal Rapier: Being a Lord, "Marth" is one of the only two characters who can use them.
• Royals Who Actually Do Something: Just not the royal she claims to be at first...
• Rubber Face: Inigo does this to her in their C support while trying to make her smile more often.
  Lucina: Gah! Ret go uh mah FAFE!
• Samus Is a Girl: As Lucina proves, it is not difficult for a woman to impersonate the male Marth.
• Set Right What Once Went Wrong: Time traveling to prevent the apocalypse.
• She-Fu: Her fighting style incorporates plenty of acrobatic flips and graceful twirls.
• She Is All Grown Up: Played backwards. It seems some of the male characters are really looking forward for present-day-Lucina to hit 18 now that they see that the future-Lucina is quite the looker. Basilio is among them, but, in his case, it's also zigzagged. He primarily wants baby Lucina as his champion once she's all grown up, rather than as a romantic partner. That being said, he does admit to finding Future Lucina attractive in his B Support with Flavia.
• Ship Tease: She gets plenty of this with the Male Avatar.
• Shock and Awe: Her Spring variant in Heroes uses thunder magic.
• Shrouded in Myth: "Marth" prefers to reveal as little about himself as possible, leading others to speculate where he came from and why he fights.
• Signature Move: Lucina will always inherit Aether, even if Chrom himself does not know it yet.
• Single Woman Seeks Good Man: All of her romantic supports have shades of this.
• Spectacular Spinning: Perfectly mimics Chrom's implausibly awesome spinning attack during a cutscene.
• Status Buff: Her Charm skill gives allies in a 3 tile radius +5 to Hit and Avoid, and in Fire Emblem Heroes her Spur Attack skills give adjacent allies boosts to their attack.
  • Her Spring variant in Heroes comes with the Rally Speed skill, allowing her to boost and ally's speed by 4 if used.
  • Her Brave variant in Heroes wields the Geirskögul which gives allies who use a sword, lance, axe, bow, or dagger within two spaces +3 to attack and speed. She also has the Drive Speed skill, giving any ally within two spaces +3 speed during combat.
• Stealth Hi/Bye: Has a really bad habit of doing this.
• The Stoic: Serious, dedicated and typically repressing her emotions, especially when she poses as "Marth", prior to revealing to Chrom that she is the future version of his recently-born daughter.
• Straight Man: Well... "Straight Woman". Usually plays this role in her most comedic moments.
• Stupid Sexy Flanders: In-universe, Lissa gets chided by Chrom for considering Lucina "kind of dreamy" while she's still going by her "Marth" disguise. Wonder how she took the news, and how he took it in retrospect when he found out who she was...
• Superdickery: "Marth" and Chrom fight early on in the Ferox arena as part of a Combat by Champion contest. Naturally, early trailers played this up to make "Marth" look like an antagonist.
  • "Marth" can kill Chrom or the Avatar, which is an instant game over, or any of Chrom's companions, who never come back. It doesn't help that this chapter is difficult for new or rusty players, as the recommended strategy is entirely offensive, and he is quite difficult. He's still a good guy through and through.
• Superpowerful Genetics: Just like her dad, she Inherited the Mark of the Exalt, AKA the Mark Of Naga.
• Suspiciously Similar Substitute: She is essentially a female Seliph, having taken up the Falchion after her father was killed by someone he trusted. She bears other similarities with both him and Lilina, since all of them are long blue-haired royals and second-generation children who lost their fathers to the antagonists in their timeline, having to fight for them. Their fathers also arguably fall under the Martial Lord archetype. In addition, Lucina and Lilina have very similar names, though the meanings are different.
  • Also, she has a fair few similarities to Lucia from Fire Emblem: Radiant Dawn. Not only are their names almost identical, but also they have long blue hair that is significantly shorter at one point for storyline reasons. They’re skilled at swordplay, and have unyielding loyalty to a specific member of royalty.
• Sweet Polly Oliver: Played with, possibly why Lon'qu — who otherwise never lost a single fight for Basilio — lost so easily to Marth.
• Take Up My Sword: How Lucina assumed possession of the Falchion.
  • Discussed in her Supports with her sibling, after the initial hilarity of the Bug incident. After they express a desire to see if they can wield Falchion as well, Lucina begins to seriously consider letting them try, believing it would be an asset to the Shepherds if someone could use her Falchion if something happened to her. However, this upsets her sibling, who realizes what she's suggesting and suddenly gets cold feet about using the sword for fear she will become more reckless by virtue of feeling more expendable. In their A Support they turn out to be perfectly capable of wielding it, but decide to forgo doing so to avoid their fears from coming true.
• Terminator Twosome: With the Hierophant/future Avatar. While Lucina came to the past to avert the Bad Future, the Hierophant followed Lucina back into the past to ensure that Grima's resurrection does come to pass.
• Think Nothing of It: Never expects anything in return for what good she does.
• Time-Travel Romance: She can get married with male Avatar.
• Tomboy Princess: She dresses in masculine clothing, takes on a male persona, and is a very skilled swordswoman, although she also has a few girly tendencies as seen in her Supports.
• Tragic Keepsake: The Falchion, her tiara, and also a pendant from her mother, which she and Gerome look for in their B support.
• Tritagonist: It's her Bad Future that the Shepherds are trying to prevent, after all.
• Twice Shy: Her S Support with a male Avatar is like this.
• Undying Loyalty: To Chrom. So much so that she is willing to kill the Avatar to protect him, provided the Avatar isn't her husband or mother, in which case she will still try, but falter and ultimately decide not to go through with it (because in that case she's just as loyal to the Avatar as she is to her father). Even if the Avatar isn't related to her, Chrom will convince her to stand down when he walks in on the confrontation.
• Unexplained Recovery: One of her flashbacks reveals that she was faced with Grima herself, with the dragon about to devour her as she holds out her sword, prepared to go out fighting... at which point the flashback ends. It's never revealed how Lucina got away. In the Drama CD, it's revealed that Gerome, Cynthia, and Noire save her from Grima.
• Unusually Uninteresting Sight: She is pretty apathetic about the quirkiness of most of her companions. She doesn't even notice there is anything odd about Noire having split personalities.
• Vagueness Is Coming: When first meeting Chrom and needing to avoid interacting as much as possible:
  "This world teeters at the brink of a horrible calamity. What you saw tonight was but a prelude. You have been warned."
  • To her credit, she doesn't stay like this. As soon as her identity is revealed, she tells everything she knows. ...except for one important detail about the Avatar. Though that case is justified, as she wanted to be absolutely certain after seeing how close the Avatar and Chrom are, as how could someone like that kill their best friend in cold blood?
• Wake-Up Call Boss: "Marth's" stats when fought in Chapter 4 are considerably higher than any prior boss, and he will also advance upon your units if they enter his range.
• Walking Spoiler: The latter part of the story cannot be done without spoiling the fact that "Marth", who really is Chrom's daughter Lucina taking on the guise of the legendary prince, hails from a Bad Future where Grima has decimated most of humanity, and has come back in time to Set Right What Once Went Wrong, along with the other children (though she is the only important Second Generation character, while the rest is technically Demoted to Extra).
• Warrior Princess: She was taught how to fight by her father, Exalt Chrom.
• Weapon of X-Slaying: Her Parallel Falchion is effective against Wyvern and Manakete units, like a Wyrmslayer, but unlike a Wyrmslayer, is also one of two weapons that can deal effective damage to Grima.
• We Cannot Go On Without You: In the Future Past 3 DLC, NPC Lucina must survive or the mission immediately fails. In regular gameplay, however, Lucina's death will not trigger a Game Over.
• What Happened to the Mouse?: Her solo epilogue indicates that after the world is saved, Lucina said goodbye to her present infant self, and disappeared. No one knows if she had departed for another land, or returned to the future.
• What the Hell, Hero?: Tiki gives her a brief one for stealing the name of Marth, whom Tiki actually personally knew. As they talk more, however, Tiki considers it to have been a worthy choice after all.
• When She Smiles:
  • The thrust of her supports with Inigo.
  • Her Spring Festival artwork in Heroes depicts her as the happiest she's ever been seen, and it makes her look absolutely adorable.
• Why Did It Have to Be Snakes?: Bugs in her hilarious C support with her sibling.
• Workaholic: Her supports reveal that, when she's not pushing herself to the point of injury during training, she's helping out the others with whatever task she can possibly find in camp.
• You Are Not Alone: Her supports with a male Avatar revolve around him reassuring her of this. This causes her to fall for him if they reach S Rank.
