Riruru
Voiced by: Yuriko Yamamoto (1986) Miyuki Sawashiro (2009)
A mysterious girl who appears before Nobita asking him about robot parts that he has been collecting recently. It is revealed that she is a female robotic spy sent to Earth to scout the area and build a robot army to take over the world. Though because she has befriended Shizuka, she begins to cast doubt on her commander and her race.
- Adaptation Dye-Job: Her hair is pinkish-orange while in the remake it's pink.
- Disappears into Light: The effect of rewriting Amu and Emu's program.
- Finger Gun: Overlapping with Finger Firearms since she's technically a robot, she can fire some sort of electric shockwave through her right index finger.
- Heel–Face Turn: After discovering humans, her supposed enemies, are capable of kindness and compassion, she turncoats on the Steel Troops.
- Heroic Sacrifice: Was willing to help reprogram Amu and Emu to prevent the invasion after going back in time, even if it meant wiping out her existence.
- My Country, Right or Wrong: She knows well that enslaving Earthlings is wrong, but her loyalty toward her planet conflicts her so much she refuses to be in the frontlines. She instead goes with Shizuka to change Mechatopia's past.
- My God, What Have I Done?: In the remake when she attempts to shoot Nobita only for Pippo to take the shot.
- Redemption Equals Death / Redemption Earns Life: Knew full well that she'll cease to exist when the past is changed, but in the end is reborn as a robot angel.
- Psychic Link: A robotic and non-supernatural variation. She and Judo/Pippo can communicate through mind link with each other because she gives Judo/Pippo a piece of her heart components.
- Really 700 Years Old: She looks like she's 15 but is really 30,015 years old.
- Ret-Gone: After meeting the original creator of the robot race and convincing him to change their programming, Shizuka realizes that this mean she would be erased as well. She goes through with the plan anyway, and her last moment before fading away is her telling Shizuka that she wishes that she'll be reborn as an angel-like robot. She gets it in the end.
- Robot Girl: She's mechanical on the inside despite looking like a human girl, in order to assist the Steel Troops in spying on humans. Shizuka was the first to discover the truth when Riruru have a Robotic Reveal.
- Set Right What Once Went Wrong: She and Shizuka travels into Mechatopia 30000 years prior to the timeline in order to tell her ancestors' creator about Mechatopia's current condition. The professor responds by rewriting her ancestor's program.
- Spell My Name With An S: "Lilulu" in some subbing.
- Technopath: To some limited extent; when Suneo controls Micross to attack Nobita early on, Riruru simply waves a finger and Micross starts attacking Suneo and Gian instead. It works only on simple, present-day robots however, hence she can't use it on Doraemon or other Steel Troop robots.
Zanda Claus
Pictured with the gang for size comparison.
Originally named "Jude", Zanda Claus is a giant robot assembled by Nobita and Doraemon as its parts are summoned at their yard as its AI controller has slipped into their house and has been locked away accidentally by Nobita's mother. While the robot is initially controlled with Doraemon's gadget controller, the AI eventually returns to the bot.
- Centrifugal Gravity: He seems to have one built in the central cockpit, which the story lampshades - as Nobita controls Zanda Claus into somersaulting, none of them feels dizzy at all. Doraemon then explains the concept of this trope to Nobita and Shizuka.
- Expy: Of Hyaku-Shiki from Mobile Suit Zeta Gundam, with the white-blue-red color scheme common to a Gundam.
- Heel–Face Turn: Or rather, FORCED Heel-Face Turn as Doraemon reprogramed his brain.
- Humongous Mecha: One so huge his parts need to arrive, bit by bit, starting with his legs and shin.
- Not So Invincible After All: After defeating scores and scores of hostile robots, being the heroes' seemingly unbeatable trump card, in the final battle he finally collapses, taken down by the robot army's Zerg Rush, much to the horror of Doraemon and the boys.
Micross
One of Suneo's radio controlled robot which has been given its own AI personality with Doraemon's gadget. Like its owner, Micross appears to be cowardly and all-talk.
- Chuck Cunningham Syndrome: Despite all versions of the story having Micros surviving to the very last scene, he seemed to have disappeared from the franchise altogether, with his master Suneo never mentioning about him again in later Long Tales. He might be sent back to Suneo's cousin (who made him in the first place) or maybe Suneo got tired of him, it's never really explained.
- Demoted to Extra: His role was heavily demoted in the remake. Only appear in the beginning and gone from the rest of the movie in favor of Pippo.
- Helicopter Pack: How he travels around.
- Named by the Adaptation: Micross is based on Suneo's unnamed prototype robot toy from "Let's Assemble a Handmade Robot " (which the movie is an Adaptation Expansion of). His original counterpart doesn't have a name, but he's called Micross here.
- Ridiculously Human Robots: Gains a human-like personality after being implanted with a 22nd-Century chip by Doraemon.
- Spared by the Adaptation: Suneo's original prototype robot from "Let's Assemble a Handmade Robot" was unceremoniously squashed at the end of the story, much to Suneo's dismay, but Micross survives the manga and both anime remakes.
The Robot General
Leader of the Steel Troops and the army's commander, as well as Riruru's direct superior. The remake sees him accompanied by a skinnier Deputy Commander.
- Big Bad: The Mechatopian General is the closest the movie has to a main villain, though he's more akin to a military leader doing his job.
- Canon Foreigner: The Deputy Commander exists only in the 2011 remake.
- Fat and Skinny: In the remake, the huge General and his taller, lankier deputy.
The Steel Troops
Foot soldiers of the Mechatopian army, lured into the Mirror-verse thanks to Zanda Claus sending a false signal. Most of the movie revolves around Doraemon and gang's efforts to keep the troops in the dark and prevent them from spilling to the real world, but inevitably all hell breaks loose.
- Cyber Cyclops: Several of their members, from their worker drones to foot soldiers, have a single red eye on their faces. Averted for their General and Deputy.
- Finger Firearms: Their basic troops fires energy bolts from the fingertips in all versions, which does minimal damage to targets. Some of them carries blasters capable of levelling buildings,
- Mecha-Mooks: Lower-class Mechatopian robots serving as construction workers in their facilities, which Doraemon and gang - and later, the reformed Zanda Claus - destroys with ease. Their soldier counterparts are far more competent and dangerous.
- Jetpack: Most of their members have jet thrusters for flight.
- Ret-Gone: Was erased from existence thanks to Riruru rewriting history and preventing the Robot War from happening.
- Robot Soldier: The troops of Planet Mechatopia, and they even follow a military hierarchy - they have a commander, and their sergeants have black markings on their shoulder.
- Zerg Rush: Attempts to overwhelm the heroes through numbers, and even took down Zanda Claus at the conclusion of the climax.
Pippo
Voiced by: Yumiko Kobayashi (2011)
His real name is Judo and is actually the brain unit of Zanda Claus. The tropes below mostly refer to his appearance in the remake due to him being nothing more than a computer in the original.
- Ascended Extra: Reprogrammed by Doraemon in the original, he's given a chick form with more screentime in the remake.
- Atrocious Alias: Pippo is the combination of "pi po", a Japanese onomatopoeia for the electronic "beeps". note He doesn't like it. Noibta gave him the name due to Judo making "pi pi po po" sounds before they transformed him with the Translation Jelly, plus Nobita reasoned that it was a much cuter name compared to "Judo". At the end before Pippo Disappears into Light, he tells Nobita that he loves the name.
- Badass Adorable: Has the appearance of a baby chick and has an amazing singing voice, but have him in control of his Zanda Claus mech, he's a walking force of destruction.
- Because You Were Nice to Me: He becomes loyal to Riruru because she repaired him after he was damaged ad thrown away for doing something a slave robot shouldn't have done. Nobita's nice attitude toward him is also what triggers his Heel–Face Turn, convincing Riruru to reconsider in the process.
- Berserk Button: Don't imply that he's trash within his hearing range, especially when he's in his Humongous Mecha body.
- Brutal Honesty: He tells off Gian about his singing voice right to his face. His own beautiful singing is what spared him from Gian's wrath.
- Disappears into Light: As the effect of rewriting Amu and Emu's program.
- Eggshell Clothing: After being hatched from it's robotic shell, Pippo wears part of the shell as a hat.
- Heel–Face Turn: A more natural one compared to the 1986 version.
- Heroic Sacrifice: When told by Riruru that her reprogramming their equivalent of robotic Adam and Eve - Amu and Emu - in the past would mean wiping out their existence in the present, he accepted it and kept fighting against the Steel Troops.
- My Country, Right or Wrong: Subverted. He's willing to fight his fellow Mechatopians to protect Nobita and his friends.
- Psychic Link: He and Riruru can communicate through mind link with each other because he has a piece of Riruru's heart component in him.
- Ridiculously Cute Critter
- Singing Voice Dissonance: This applies to his original form since he communicates through beeping sounds.
- Redemption Equals Death / Redemption Earns Life: Knew full well that he'll cease to exist when the past is changed, but in the end is reborn, appearing as an adult Phoenix-like bird.
- Took a Level in Kindness
- Tsundere: Type A. Like the Steel Troops, he has a hatred of humanity, but time spent with Nobita and the gang softens him. Nobita telling him that he doesn't want to fight him causes him to break down and cement his Heel–Face Turn.
- Verbal Tic: "Piyo", an onomatopoeia of "cheep". Which incidentally leads to his Atrocious Alias.
