The third animated season in the ''[[Franchise/LyricalNanoha Magical Girl Lyrical Nanoha]]'' franchise.

''Magical Girl Lyrical Nanoha [=StrikerS=]'' takes place [[TimeSkip ten years after the second series]], with the previous cast having become high-ranking members of the TSAB.

Following the emergence of a new type of [[LostTechnology Lost Logia]] called Relics, Nanoha, Fate and Hayate seek permission to form "Section Six", an elite rapid response team and training squad composed of powerful veterans and talented rookies.

As their investigation into the Relics continues, Section Six comes into conflict with MadScientist Jail Scaglietti and his [[ImprobablyFemaleCast all-female]] group of [[SuperSoldier cybernetic operatives]], the Numbers. Jail is the mastermind behind a number of illegal projects, such as the creation of Artificial Mages and Combat Cyborgs, and now he has his eye set on the Relics. Section Six also runs into Vivio, a orphan of the same "Project F" that [[CloningBlues created Fate]], who Nanoha and Fate decide to adopt as their own child. When Vivio is suddenly kidnapped by Jail, who intends to use her as the lynchpin of his ultimate plan, Section Six must mobilise to save her and stop Jail's plans once and for all.

Unlike the first two seasons, this one had a full 26 episodes [[TwelveEpisodeAnime instead of 13]]. It had the [[LoadsAndLoadsOfCharacters largest cast so far]] and [[GenreShift shifted the tone]] to a [[DarkerAndEdgier darker]], more [[MilitaryScienceFiction SF/military]] feel.

It has a supplementary SliceOfLife manga and [[AudioAdaptation Sound Stages]] that take place between the episodes. ''Audioplay/StrikersSoundStageX'' could be considered its SpinOff, as it only features the new characters from this season.

'''NOTE:''' Only general tropes for the series are listed here. For character-specific ones, check out the '''[[Characters/MagicalGirlLyricalNanohaStrikers character]] [[Characters/LyricalNanoha sheets]]'''.

!!''MGLN [=StrikerS=]'' contains examples of:
* AbsurdlySpaciousSewer: The site of a battle.
* AdultFear: The finale began with the simple yet real fear of losing your child because you were away when they needed you most.
* AgentsDating: Subaru and Teana (agents of a special counter-terrorist unit) hang out together on their day off—which is [[ShipTease technically not a date]] — but it's cut short, anyway, when they accidentally rescue the resident MacGuffin Girl and are ordered to RTB.
** Erio and Caro also get cute scenes with a date-like overtone to them (complete with ShipperOnDeck telling them where to go).
* AlienSky: Mid-Childa has a lot of moons.
* AllYourBaseAreBelongToUs: The assault on the Riot Force 6 HQ.
* AmazonBrigade: Riot Force 6 in general, not counting Erio and Zafira.
* ArtifactTitle: While the entire cast is seasoned mages, they barely fit the "Magical Girl" archetype aside from Caro. Teana is a gunslinger, Subaru is [[spoiler:a HollywoodCyborg]], Nanoha and Fate are 20-ish military combat instructor and career officer, Erio is [[TheOneGuy a token male]], and "Lyrical" has not been seen since episode one of season one.
* BanOnMagic: In episode 5, it's revealed that clearance is required for use of personal flight in populated areas, due to the fact that it could cause problems with air traffic.
* BeamOWar: The only times in the franchise where it's played straight is Nanoha's [[CurbStompBattle "fight"]] against Dieci, Caro & Friedrich vs. Lutecia & two Jiraiou, and Voltaire vs. Hakuten'ou.
* BeamSpam: Played with. The anime and manga warn that dismissing battle strategy in favor of zerging enemies puts an unhealthy strain on the body. [[spoiler:Foreshadowing as Nanoha's Blaster mode damages her linker core so badly she's recovering years after]]
* {{Bookends}}: The season begins with a young Subaru shouting for help while she's trapped in a burning airport, and Nanoha coming to save her in the nick of time, congratulating her for doing well to survive and assuring her that she'll bring her to a safe place. Subaru's WhereAreTheyNowEpilogue has two young children (who look like younger Subaru and Ginga with blonde hair) shouting for help while trapped in a sinking ship, and Subaru saving them in the nick of time [[MeaningfulEcho while echoing the same words Nanoha told her many years ago]]. Bonus points for the fact that Subaru's Barrier Jacket was modeled after Nanoha's.
* BrainInAJar: [[spoiler:The TSAB high Council]]
* BreakOutTheMuseumPiece: The Arthra is planned to be scrapped; however, the heroes decide to use it as their command center [[spoiler:after the Long Arch was destroyed.]]
* BusmansHoliday: In Episode 10, the Forwards' day off is cancelled when they find Vivio and two Relics, leading into a battle that spans the next two episodes.
* ButNotTooForeign: The three members of the Nakajima family and the name Nakajima itself sound pretty Japanese despite they are from Mid-Childa. This is justified because Genya's ancestors came from Japan. However, their first names and family name are written in western order and in katakana to emphasize their foreign nature.
* CallBack: When Nanoha uses Starlight Breaker against [[spoiler:Vivio]], her pose and the camera angle are identical to when she used it against Fate back in the first season.
* ChekhovsSkill: The very first episode starts out with Nanoha blasting through the walls of a burning airport in order to secure a safe path for her to fly out Subaru. In the penultimate episode, the same scene shown again [[spoiler:when Quattro realizes that Nanoha plans to [[DungeonBypass blast through the walls of the Saint's Cradle in order to blast]] ''[[DungeonBypass her]]''.]]
* CherryBlossoms: In the final episode.
* ChurchMilitant: The Saint Church has its own armed force of comparable power to the TSAB Ground Forces.
* ConspicuousCG: The helicopters.
* ContinuityNod: [[spoiler:Megane Alpine]]'s wheelchair looks exactly like Hayate's.
* CoolStarship: [[spoiler:The Saint's Cradle]].
* CostumeExaggeration: Nanoha and Fate change their previously more mundane MagicalGirl uniforms for slightly more complicated and extravagant versions, though Fate was actually ''downgraded'' from her [[{{Stripperiffic}} infamous]] previous outfit. This time, however, it's more indicative of Nanoha and Fate growing up 10 years and thus outgrowing their nine-year-old selves, and ultimately they switch back to the old outfits two thirds of the way in, mostly to indicate they're getting serious.
* DarkerAndEdgier: While nowhere near the level ''[[Manga/MagicalRecordLyricalNanohaForce Force]]'' would later reach, it still traded in most of the MagicalGirl trappings for military sci-fi tropes and revealed the near-fatal consequences of overdosing on BeamSpam among other things.
* DemotedToExtra: Yuuno, Chrono, Lindy, Zafira, Shamal, Arf, and arguably even Hayate suffer from this.
* DeusExitMachina: During the press conference, Nanoha, Fate and Hayate are required to turn over their Devices to the Forwards in order to go in. This costs them valuable time when Scaglietti's forces attack.
* DieHardOnAnX: The end of the season has the Riot Force Six and the Ground Force headquarters destroyed, Ginga and Vivio captured, most of their forces injured, and now it's up to Nanoha, Fate and the trainees to work their way from square one into Scaglietti's headquarters and blow his entire operation from inside.
* EveryoneIsASuper: Once they get off a certain InsignificantLittleBluePlanet. Mid-Childa is populated by mages, making magic use mundane. Of course, the heroes' [[StuffBlowingUp signature type of magic]] is still second to none.
* EvilIsNotAToy: Regius and the high council fund Scaglietti's (a known criminal) research in order to develop new weapons and tech for the TSAB. Scaglietti of course develops weapons to fund his own agenda and turns on them. Might be a case of OutGambitted as they were planning to betray him and he got there faster.
* ExactTimeToFailure: The last few episodes end with how much time is left before Scaglietti's plan succeeds.
* {{Fauxshadow}}: Vita speaks about her mortality several times, then towards the end of the series gets several opportunities to go out in a blaze-of-glory, but then she gets better. This does, however, show the Wolkenritter's CharacterDevelopment in dealing with their mortality, as well as having causes they're willing to risk their lives for.
* FireIceDuo: The series has two [[RobotGirl Unison Devices]]: Reinforce Zwei of the Yagami family and Agito, an ally of the BigBad. Agito has a built-in affinity for fire magic -- a phenomenon known in the series as "Mana Conversion Affinity", of the flame-type in this case,--and while there is no canonical equivalent for ice-based magic, Rein's offensive spells are all cold-based. Needless to say, the two of them rapidly develop an intense rivalry (especially since Rein has a designated master, while Agito technically doesn't), which gets resolved at the end of the season by [[spoiler:Agito being adopted into the Yagami family, as well]].
* {{Foreshadowing}}: There's plenty when one pays attention, but a key one is Subaru and all the [[SuperStrength hints]] dropped before TheReveal [[spoiler: that she's a cyborg.]]
* FreezeFrameBonus: Yuuno's ferret form can be seen at the bottom left of episode 13's EyeCatch.
* {{Gainaxing}}: Fate, Nanoha, and Subaru's breasts noticeably jiggle in their transformation sequences.
* GenreShift: In ''[=StrikerS=]'', the series branches out into a more sci-fi fantasy/military genre.
* TheGlovesComeOff: While various characters (and their devices) have PowerLimiters that are inevitably removed to give them a power boost, the gloves coming off in the psychological sense happens twice in [[WhamEpisode episode 17]]:
** First, Subaru finds that Cinque, Nove, and Wendi [[spoiler:having just defeated Ginga, are loading her up to take her back to Scaglietti for reprogramming]]. Subaru ''[[UnstoppableRage loses her mind]]'' at the sight of this and immediately attacks all three of them [[spoiler:using her Inherent Skill, revealing that she's also a combat cyborg]]. She forces Nove and Wendi to retreat while Cinque [[YouShallNotPass holds her off]], but defeats Cinque in short order as well, though [[{{Intangibility}} Sein]] manages to save her. Then Subaru collapses, from the combination of [[HeroicRROD the massive damage she inflicted on herself as well as the Numbers]] and the fact that [[spoiler:she couldn't stop them from taking Ginga with them when they fled]].
** Later in the episode, Caro and Erio arrive at Riot Force 6 HQ in response to a distress call, just in time to see Lutecia kidnaping Vivio. They try to stop her, but are blindsided by Deed and Otto, who take out Erio and Fried before fleeing, leaving behind a small army of gadget drones and an automated announcement that they will be destroying the HQ building momentarily. Caro, the last defender standing at this point, summons Voltaire -- the {{Kaiju}} sized guardian dragon of her homeworld, who can only be called at great need. [[CurbStompBattle Voltaire wipes out the drones with a single attack.]]
* HeroicAmbidexterity: Teana Lanster is ambidextrous, which doesn't escape her future mentor's notice in the manga, so the new Device she organizes for Teana is [[GunsAkimbo a pair of handguns]].
* HomeFieldAdvantage: The Saint's Cradle, which gives an edge to the Combat Cyborgs because they aren't affected by the huge magic dampening field all around the ship.
* HypotheticalFightDebate: A two-parter chapter of the manga revolves around the younger members of Riot Force 6 arguing about who of the [=RF6=] aces would win in a fight. All that's known is that [[BigGood Hayate]] [[UnskilledButStrong would not]].
* IKnowYoureInThereSomewhereFight: [[spoiler:Subaru vs. Ginga]], Nanoha vs. Sankt Kaiser Vivio, and Caro and Erio vs. {{Mind Control}}led Lutecia. Subverted in that talking didn't really help much in any of the cases and the mind controlled parties were only stopped the old-fashioned way - by a thorough befriending. Hey, it's ''Nanoha'' after all.
* InterserviceRivalry: The Navy and the Ground Forces dislike each other and try to one up each other constantly. The factions and rivalry come to a head when Regius, head of the Ground Forces, turns to Scaglietti's research and hides it from the rest of the TASB.
* KidHeroAllGrownUp: Former KidHero Nanoha is an adult from ''[=StrikerS=]'' onward.
* {{Koan}}: "To defeat someone stronger than you, you must not be weaker than that person." This gets a few interpretations, but is never conclusively explained.
* LateArrivalSpoiler: The Wolkenritter's HeelFaceTurn and Fate's adoption into the Harlaown family.
* LikeAnOldMarriedCouple: Doing nothing to stop the HoYay between the two, Nanoha and Fate lapse into this at times. Of note is when the're arguing about how to raise Vivio.
* LoadsAndLoadsOfCharacters: The best example of the franchise, as ''[=StrikerS=]'' introduces more characters than any other ''Lyrical Nanoha'' series. Its character sheet is the largest so far.
* LoopholeAbuse: The TSAB doesn't allow too much raw power on the same squad. Nanoha, Fate, and Hayate together are way over the stated power limit. Their solution is to have power limiters to artificially keep their collective rank under the stated limit. See the rest under PowerLimiter.
* LostSuperweapon: [[spoiler:The Saint's Cradle]].
* LuckyTranslation: Sein and Wendi call Quattro "Megane-nee" or "Mega-nee" when not in her presence. There's a direct translation in "Glasses-sis" and "Glass-sis", which has exactly the same pun.
* LyricalColdOpen: No pun intended. It means that second ending theme, "Beautiful Amulet," starts with lyrics right off the bat.
* MacGuffinSuperPerson: Vivio, who is sought after by the villains because she's [[spoiler:[[CloneJesus the clone of the]] [[CrystalDragonJesus last Sankt Kaiser]], and they need her to activate and control [[CoolStarship the Saint's Cradle]]]].
* MeaningfulEcho: Several in the finale, and they're all SugarWiki/HeartwarmingMoments.
** Vivio trips in episode 15 and Nanoha tells her to try and stand on her own, but she is unable to do so. [[spoiler:In the finale, Vivio manages to remain standing after being hit with '''Five''' Starlight Breakers because "I can stand on my own".]]
** [[spoiler:When she heads to take care of the Cradle's engine, Vita tells Nanoha "[[BadassBoast The Knight Vita of the Iron Hammer, and the Steel Count Graf Eisen. There's nothing in this world we can't destroy.]]". Hayate says an extended version of the line back to her when [[SugarWiki/AwesomeMoments she lives up to that claim]].]]
** The exchange between Nanoha and Subaru at the beginning of the season was repeated almost word for word when Subaru saved some children in the epilogue. Doubles as {{Bookends}}.
** When talking about memories of her original owner in the third sound stage, Agito says "Strangely, my heart feels warm." [[spoiler:Signum says the same thing to her the first time they unison.]]
* MedicalHorror: Some of Scaglietti's more depraved experiments jump right into this. Especially his end-of-season backup plan.
* MilitaryMoe: In contrast to previous entries in the franchise, the magical girls in this series operate as a military unit, with at least MildlyMilitary discipline, instead of being temporary assistants to enforcement operations.
* MoodWhiplash: Good lord, everything that happens from episodes 15 to 18. [[spoiler:In episode 15, the Forwards get in some good-natured casual training, [[CrowningMomentOfHeartwarming complete with some cute sibling bonding, Vivio is shown getting adorably comfortable with her new mothers]], and then it suddenly ends in a very solemn discussion about the imminent attack. Episode 16 continues the light-heartedness for the first half, until the predicted attack happens. In episode 17, everything just goes to hell - almost everyone at Section Six is injured, the surrounding area is in ruins, Ginga is captured, Vivio kidnapped, and [[TearJerker the last shot of the episode is of the stuffed rabbit that Nanoha bought for Vivio, mangled and on fire inside the burning building. Finally, in episode 18, we see the aftermath of the battle and the damage. Nanoha keeps herself busy to try and distract herself from Vivio's kidnapping, but that fails when she finds what's left of the stuffed rabbit. The episode ends in Nanoha breaking down into tears in Fate's arms, while Vivio is strapped to an operating table by the villains, fully aware of what they are about to do to her, screaming for Nanoha to help her]].]]
* MortalityEnsues: The Wolkenritter realize that this is happening to them as a result of their connection to Hayate. They're pretty accepting of it.
* OffscreenMomentOfAwesome: The season ends with the beginning of a mock battle in which the four Forwards face Nanoha, Fate, Vita and Signum, but none of it is shown. The manga shows a bit of the result. The winner is unknown, but the [[ClothingDamage Barrier Jackets and Knight Clothings are really, really badly damaged.]]
* ParentsInDistress: Invoked. Quattro tells Vivio that Nanoha is in danger, and all she has to do to get her back is to defeat the demon in front of her. The "demon" in question was Nanoha, but Vivio had been tortured so much in the past few episodes that she honestly thought that she was a monster disguised as her mama in an attempt to deceive her.
* PeopleJars: Jail Scaglietti loves these. They contain unfinished and injured cyborgs [[spoiler:and Lutecia's comatose mother]].
* PowerLimiter:
** Nanoha, Fate, and Hayate have them, partly due to the office politics of having too many powerful mages in one department, but also because it disguises the amount of power Section Six has at its disposal from their enemies, [[IAmNotLeftHanded giving them the element of surprise when necessary]]. The ''real'' reason is that they were starting to go OffTheScale and could have easily [[CurbStompBattle curb stomped]] all opposition without needing any help from [[NewMeat the Forwards]], which they very nearly do in the final battle.
** A four-level limiter is applied to the Forwards' own Devices so they can ease into the power they receive. One level typically gets taken off before each major battle.
** Lutecia also gets a six-rank limiter as part of her sentence.
* ProphecyTwist: A vaguely worded prophecy mentions the "destruction of the ship of law that guards the stars". Everyone assumes, given the seemingly easy conclusion of an earlier part referring to a disastrous terrorist attack, that this refers to the TSAB Headquarters. Turns out, [[spoiler:it's referring to the ancient warship the BigBad manages to excavate, thus prophesying that they'll manage to stop it]].
* RankInflation: In Season 1, the scale goes up to AAA. By ''[=StrikerS=]'', [[GlassCannon Hayate]] is ranked ''SS'', and Nanoha, Fate and Signum are all S-ranked.
* SaintlyChurch: The Belkan Saint Church.
* SandersonsFirstLaw: The ''Nanoha'' series has always been fairly consequential about how its magic works, but it really comes to shine during the final battle of ''[=StrikerS=]'', when Nanoha utterly destroys [[spoiler:Quattro]]'s schemes by combining two basic abilities the audience already observed her use many times: [[spoiler:Area Search, which finds whatever Nanoha wants to locate, and Divine Buster, which blasts anything dumb enough to be in the White Devil's way into oblivion]].
* ShipSinking: Fate/Chrono already took a blow after Chrono's mother adopted Fate at the end of ''A's'', but it and Nanoha/Chrono is only finally sunk when Chrono [[spoiler:marries Amy]].
* ShootingGallery: Subaru and Teana go through one of these on the first episode for their B-Rank qualifying mage exam.
* ShoutOut:
** In episode 7, Zafira yells to let a group of Gadget Drones know that they [[LordOfTheRings "shall not pass"]] as he stomps once on the ground which causes large cracks to appear.
** In one of the {{Omake}} chapters, Rein cosplays as [[Manga/CodeGeass C.C.]]
* SnipeHunt: Lutecia's search for the Lost Logia turns out to be this. Jail tells her to find a specific Relic with the promise that it would bring back her mother. [[spoiler:Later, it's revealed that her mother was not only not dead but an enemy of his placed in a forced coma. He only gave her the task to keep her loyal.]]
* SoundOff: The Ground Forces trainees in the manga, in a ShoutOut to ''Film/FullMetalJacket''.
* SpoilerOpening: The second opening shows who most of the cast fights in the final battle.
* StormingTheCastle: A two-in-one combo for the final showdown: Fate, Schach and Verossa attack Jail Scaglietti's lab, while Nanoha, Hayate, Vita, and a ton of air mages attack the Saint's Cradle.
* SwivelChairAntics: There's an adorable scene in episode 3 where Reinforce Zwei spins around at her new desk. It's made all the more adorable by the fact that she (and the desk) are less than a foot tall.
* TalkingInBed: Twice. Neither case had anything to do with relationships, but they were both full of LesYay:
** Hayate, Nanoha, and Fate have a discussion during a flashback that led to the creation of Riot Force 6 in what appears to be a hotel room.
** Nanoha and Fate had on in their shared room while talking about the Forwards.
%%* TheTeam: Riot Force 6.
* TimeSkip: Six years between ''A's'' and the first six chapters of the manga then another four to series proper.
* TitleDrop: Fate explains the designation/title of "Striker" to the Forwards.
* TrainJob / TraintopBattle: In Episode 5 the Gadgets attempt to steal a Relic form a train and the Forwards get their first chance to kick ass.
* TrainingFromHell: Subverted in Episode 9, where the dangers of over-training to the point where it damages your body are a major plot point.
* UnusualUserInterface: The Numbers use holographic piano keyboards.
* UpgradeVsPrototypeFight: One of the final battles had [[TheLancer Fate]] facing against the [[QuirkyMinibossSquad Numbers]] {{Cyborg}}s [[TheDragon Tre]] and [[BattleBoomerang Sette]]. Fate was [[SuperPrototype the first successful]] [[SuperSoldier Artificial Mage]], while the Numbers {{Cyborg}}s are enhanced versions of that, with Tre in particular being the most powerful of the cyborgs in combat.
* WhamEpisode: Episode 17. Several details about character's backstories are revealed, and the bad guys for the most part score an overwhelming win. [[spoiler:Subaru and Ginga are combat cyborgs like the Numbers, Erio is confirmed to be a clone of the original Erio Mondial, the press conference attack is revealed to be a diversion for an attack on Riot Force 6's base, which leaves it utterly wrecked, Vivio and Ginga are kidnapped and most of the heroes who aren't too late to do anything are left either badly damaged/wounded.]]
* WhereAreTheyNowEpilogue: Takes place a few months after the events of the series.
* YouShallNotPass: In a villainous example, Cinque pulls one of these against Subaru in episode 17 in order to let Nove and Wendi escape [[spoiler:with Ginga, who they've just beaten unconscious and are bringing back to Scaglietti]]. Subaru damn near kills her, and she only makes it out because [[{{Intangibility}} Sein]] arrives to rescue her.
