The third season in the ''[[LyricalNanoha Magical Girl Lyrical Nanoha]]'' franchise and so far the last to be animated.

''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 [[ScienceFiction 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 feature the new characters from this season.

----
!!''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.
* 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 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.
* 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.
* 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.
* 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/NanohaForce 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.
* 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.
* 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.
* 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.
* 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.
* GenreShift: In ''[=StrikerS=]'', the series branches out into a more sci-fi fantasy/military genre.
* 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]].
* IKnowYouAreInThereSomewhereFight: [[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.
* {{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.
* 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.
* MedicalHorror: Some of Scaglietti's more depraved experiments jump right into this. Especially his end-of-season backup plan.
* 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]].]]
* 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.]]
* 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 even worse things to come if they're not averted. 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.
* 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 [[CodeGeass C.C.]]
* SoundOff: The Ground Forces trainees in the manga, in a ShoutOut to ''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.
* TheTeam: Riot Force 6.
** TheLeader / BigGood: Hayate Yagami
** TheLancer: Reinforce Zwei
** SergeantRock / TheHeroine / TheAce: Nanoha Takamachi
** FairCop / FragileSpeedster / TheAce: Fate T. Harlaown
** MultiMeleeMaster: Signum
** GlacierWaif: Vita
** CombatMedic: Shamal
** TeamPet: Zafira, Friedrich
** CuteBruiser: Subaru Nakajima
** TheSmartGirl: Teana Lanster, also TheLeader of the Forwards
** TheOneGuy: Erio Mondial (the only guy who actually fights on the front-lines)

** SixthRanger: Ginga Nakajima
** RightHandHottie: Griffith Lowran
** BridgeBunnies: Shario Finienno, Alto Krauetta and Lucino Lilie
** FriendlySniper: Vice Granscenic
* 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.
* WhereAreTheyNowEpilogue: Takes place a few months after the events of the series.
