''Doraemon: Nobita and the Steel Troops'' is a 1984 anime film based on the seventh entry of ''Manga/DoraemonsLongTales''.

* GilliganCut: This funny scene early on, after Suneo boasts his new kid-sized robot toy, Micros, in front of Nobita ad Shizuka. Nobita leaves the scene, insisting he's NOT envious over Suneo.
--> '''Nobita''': I'm ''not'' jealous. It was just a stupid toy. Why do I have to be jealous over that stupid thing?
--> [one scene later]
--> '''Nobita''': '''[[SuddenlyShouting I'm so jealous!]]'''

* MassOhCrap: All of the heroes, when they realize the entirety of the robot army [[spoiler: is now heading for the lake at Mount Uta, Doraemon deducing that they have discovered the truth that the ''real'' world they're supposed to sonquer is on the other side]].

* EurekaMoment: In the anime and original manga, Shizuka and Micros is watching after the caged-up Riruru as Doraemon and the boys are at the lake fending off the robot army, a frustrated Micros angrily complains that he'd go back in time to tell off the robots' creators for making them so hyper-competitive. [[spoiler: This suddenly gives Shizuka an idea – they CAN indeed go back to time, at which point Shizuka, Riruru and Micros hops on the TimeMachine in Nobita's room and travels to Planet Mechatopia 30,000 years earlier to inform the creator of Amu and Emu of the war in the future]]. The remake have Riruru coming with the idea ''herself'', though.

* YouHaveFailedMe: The robot commander, learning of [[spoiler: Riruru's HeelFaceTurn]], orders for her to be locked up so he can ''personally'' dismantle her in afterwards. Luckily Nobita and Doraemon is around...

* CoversAlwaysLie: The 2011 remake have Doraemon's sister, Dorami, showing up on the front poster and promotional materials, suggesting she will play a major role. Instead, she only appears for one scene.

* CoversAlwaysLie: The 2011 remake have Doraemon's sister, Dorami, showing up on the front poster and promotional materials, even though she's NOT in this movie. She's not even referenced by name!

* RetGone: [[spoiler: The fates of Riruru and the ''whole robot army'' (and in the remake, Chippo) at the end, after the past was changed thanks to Riruru and Shizuka]].

* WorthyOpponent: Machatopian Army Commander consider Doraemon and friends as this, for they are brave enough to stand their ground and defend their home planet despite getting outnumbered and outgunned.

The anime and movie receives a 2011 remake, ''Doraemon: Nobita and the New Steel Troops ~Winged Angels~'', which fleshes out both Riruru and Zanda Claus, the new characters. Notably, Zanda Claus' brain turns out to have a sentient mind of it's own, hatching into a chick named Pippo.

* CoversAlwaysLie: The 2011 remake have Doraemon's sister, Doralin, showing up on the front poster and promotional materials, even though she's NOT in this movie. She's not even referenced by name!

* DefiantToTheEnd: The final battle at the lake ends with [[spoiler: Zanda Claus being defeated as Doraemon, Nobita, Gian and Suneo gets taken alive by the robots]]. Gian, however, is defiant enough to [[ShoeSlap kick his shoe into a nearby robot mook]] while struggling and cursing at his captors, not that it did him any good. Thankfully, the very next scene had [[spoiler: the RetGone happen]]...

* HoldTheLine: Twice from Doraemon and friends when they need to prevent the robot army from passing the portal from the mirror-verse to the ''real'' world

* MonumentalDestruction: To nobody's surprise, the robot's destruction montage including shattering the Statue of Liberty, blowing up the Eiffel Tower, and crushing the Tower of London.

* CyberCyclops: The foot soldiers and sergeants of the Mechatopia robot army has only a single eye in the center of their faces, as do some of their common worker drones (which Nobita and friends find themselves fending off while destroying the first robot facility). Their commander averts it with having two eyes.

* ShootTheRope: A robot guard had [[spoiler: Riruru]] handcuffed to him while dragging her to her punishment cell, but Nobita and Doraemon comes to the rescue, with Nobita shooting the cuff's chain with a laser pistol ([[ImprobableAimingSkills who else can be so precise]]?) and Doraemon firing a second shot taking down the guard.

* MechaMooks: The army of robots from Mechatopia coming over to enslave the rest of humanity. Them being machines allow Doraemon, Nobita, Suneo and Gian to destory in massive amounts without any gore or blood.
* NearVillainVIctory: [[spoiler: The final battle has Doraemon and the boys, with Zanda Claus, getting defeated despite their valiant efforts, after a lengthy battle. Zanda Claus is taken down, the heroes are surrounded, and the robot army is ''seconds'' away from entering the lake into the real world... and then the RetGone happens]].

* PortalPool: Doraemon and friends use Shizuka's bathtub, dabbled with the Come to the Reverse World Oil, to enter the MIrror-verse. Later on in order to create an entrance large enough to lure the invading robot army from the real world to the Mirror-verse, Doraemon uses a whole can of the Come to the Reverse World Oil to turn the lake in Mt. Ura into a giant portal. Leading to entire ''armies'' of robot soldiers swarming through the pool thanks to receiving Zanda Claus' radio signal.

* WhatDoesThissButtonDo: While Nobita, Doraemon and Shizuka are taking a stroll in the middle of Mirror!Tokyo in Zanda Claus' cockpit, Shizuka enquires what the buttons in Zanda Claus' cockpit does (since they're piloting it with a remote Doraemon is using). When Nobita and Doraemon admits they don't know, Shizuka randomly presses a button... and reveals the robot's massive laser cannon in it's belt which ''levels'' a nearby skyscraper, much to the trio's shock. Luckily it's an empty building due to being in the mirror-verse, but this leads to Doraemon coming to the ultimatum that they should keep Zanda Claus' existance a secret.

Soon enough, Nobita does end up with a giant, building-sized mecha, which Doraemon denies being one of his gadgets, while a mysterious RobotGirl named Riruru shows up in Tokyo claiming the giant robot currently in Nobita's possession - which Nobita nicknames "Zanda Claus" - belongs to her. And then an army of hostile robots from the distant planet of Mekatopia starts targeting Earth.

* AdamAndEvePlot: [[spoiler: The robots of Mekatopia are actually descended from two robots named Amu and Emu, created by a human scientist who is the [[LastOfHisKind last human alive in a barren world]] who wishes to form a peaceful utopia]].

* AIIsACrapshoot: [[spoiler: As Shizuka and Riruru finds out after travelling to Mekatopia in the past, the robots are intended to create a utopia, instead of creating an unequal society and eventually invading planets. As it turns out, the two robots from which the robots are descended have competition instinct programmed in them, causing them to sacrifice others for their own good]]. Though it takes generations of robots for the trope to have full effect, which is a much longer time compared to most other examples.
* AlternateSelf: [[spoiler: Moments before she's erased from existence, Riruru apologizes of her actions to Shizuka and wishes if she can be reborn, she'd like to return as an angel in an alternate timeline, which the rest of the heroes learns afterwards. In the final scene, Nobita does meet Riruru again... an alternate version who is born in a peaceful Mekatopia full of benevolent robots, where she is a tourist instead of a spy]]. The anime also have [[spoiler: alternate!Pippo with Riruru in the final scene]].

* HeroicSacrifice: [[spoiler: Essentially what Riruru did in the end; realizing it may be too late to reprogram Amu and Emu and remove their competition instinct, Riruru decides to do it ''herself'', even though this could very well erase her from existance. She succeeds, and then starts to [[DisappearsIntoLight dissappear into light particles]] when history rewrites itself, her last words being telling Shizuka she wished she could be friends with her in another timeline]]. It seems to have worked, though: [[spoiler: the last scene in Nobita, then alone after school, seeing the reborn Riruru, now an angel from a benevolent, non-violent robot planet]].

* KeepingSecretsSucks: After Nobita has to hand over the Roll-Up Fishing Hole containing the PoolPortal to Riruru, the latter who demands he keep their meeting a secret. Nobita becomes quiet and moody trying not to let his family know about it, finally losing it at dinnertime when his dad Nobisuke randomly mentions his colleague's interest of fishing while his mom Tamako talks about a friend of hers spending so much time applying make-up before a mirror. Doraemon realize Nobita's peculiar behaviour, puts two-and-two together, and caught Nobita sneaking to the fishing-hole at night before discovering the robot invasion conspiracy.

* PortalPool: Doraemon and friends use Shizuka's bathtub, dabbled with the Come to the Reverse World Oil, to enter the MIrror-verse. Later on in order to create an entrance large enough to lure the invading robot army from the real world to the Mirror-verse, Doraemon uses an entire can of the Come to the Reverse World Oil to turn the lake in Mt. Ura into a giant portal. Leading to entire ''armies'' of robot soldiers swarming through the pool thanks to receiving Zanda Claus' radio signal.

* RippleEffectProofMemory: [[spoiler: After the RetGone, there's no reason why Nobita and friends would even ''remember'' anything about Riruru, or have any memories about the robot invasion, since they're now in a timeline where the robots of Mekatopia are peaceful and the invasion never occurred in the first place. But they still do in the aftermath, with Nobita staying back in school and missing Riruru]].

* RetGone: [[spoiler: The fates of Riruru and the ''entire robot army'' (and in the remake, Chippo) at the end, after the past was changed thanks to Riruru and Shizuka]].

* WhatMeasureIsAMook: This trope is probably the reason why Nobita and friends decide to fix Riruru, a robot designed to look like a human girl around their age, despite Riruru ''actually'' trying to kill Nobita and Doraemon earlier during the forest chase, and attempting to strangle Shizuka the moment she wakes up (before getting knocked out). Meanwhile, the common robot drones, guards and soldiers (none of them human-looking) are killed by the multiple ''dozens'' without a single care, especially when Zanda Claus uses the WaveMotionGun to level enemies entire platoons at a time.

* EurekaMoment: In the anime and original manga, Shizuka and Micros is watching after the caged-up Riruru as Doraemon and the boys are at the lake fending off the robot army, a frustrated Micros angrily complains that he'd go back in time to tell off the robots' creators for making them so hyper-competitive. [[spoiler: This suddenly gives Shizuka and idea – they CAN indeed go back to time, at which point Shizuka, Riruru and Micros hops on the TimeMachine in Nobita's room and travels to Planet Mechatopia 30,000 years earlier to inform the creator of Amu and Emu of the war in the future]]. The remake have Riruru coming with the idea ''herself'', though.
