Characters from Doraemon: The Record of Nobita : Spaceblazer, for both the manga, original anime film and remake.
Civilians of Planet Koya Koya
Ropporu
- Adaptation Dye-Job: His hair is exceptionally dark in the original anime movie, with the remake following closer to the original manga.
- Big Brother Instinct: After his father's death, Ropporu sees to it that no harm comes to his mother and little sister.
- If I Do Not Return: He says this to his little sister, Clem, before going off to infiltrate the Gartite Corporation's mines, that if he gets captured by Borgant's mooks, she must then leave with his mother immediately.
- You Killed My Father: His father was killed by the Gartite Corporation because He Knows Too Much. Most of the story revolves around his efforts to expose the Gartite for the true villainous scum they are.
Chammy
- Interspecies Romance: She's an alien bunny-rabbit, and Doraemon is a robot cat. Do the math.
- Ship Tease: With Doraemon, of all the people.
- Talking Animal: A talking bunny rabbit, even if she is from another planet. Even then, the native wildlife of Planet Koya Koya are incapable of speech either.
- Trademark Favourite Food: Thanks to being introduced to it by Doraemon, she develops a craving for Dorayaki. Doraemon is more than happy to share his massive dorayaki supply in his Fourth Dimensional Pouch with her.
Clem
- Adaptational Badass: In the remake, she shows up in the climax helping Gian, Suneo and Shizuka in saving Nobita, Doraemon, and Ropporu.
- Adaptation Dye-Job: Like her brother, Clem have dark-colored hair in the first anime movie. The original manga and the remake on the other hand have the same light green tone.
Gartite Mining Corporation
Borgant
- Big Bad: He's the main villain of this story, and commands the Gartite Mining Corporation to mine Planet Koya Koya of all her resources... even if it means destroying the live hoods of all her citizens.
- Corrupt Corporate Executive: An executive of a powerful mining corporation who's willing to murder any witnesses to his activities and later on blow up an entire planet for the residual unobtanium supply!
- Non-Action Big Bad: Unlike his lesser minions, Borgant prefers commandeering his activities from the comfort of his office.
- Screw the Rules, I Have Money!: He repeatedly evades arrest and capture by the authorities by bribing the right people, which allows him to enforce a strong grip on Planet Koya Koya. But the moment he tries nuking the planet, he officially went too far.
- Sinister Shades: He's shown wearing shades in the original manga and the remake. Not the first anime adaptation however, where he wears glasses instead (making him closer to Four Eyes, Zero Soul).
- Suspiciously Similar Substitute: Him being a rich douchebag and Corrupt Corporate Executive who would take extreme measures to get what he wants, and have no qualms directly attacking children, makes him another Dolmanstein.
- Villain: Exit, Stage Left: Borgant attempts to flee when realizing the detonator is about to blow Planet Koya Koya into bits, but was stopped by the Galactic Police.
Uno and Doubt
Uno
Doubt
Two Gartite enforcers who constantly pursue the heroes. They serve Borgant directly, but they're kind of useless.- Bumbling Henchmen Duo: Always seen together, and they're not very good at their jobs.
- Butt-Monkey: They repeatedly, repeatedly, repeatedly get their butts handed back to them on a silver platter once Doraemon and Nobita discover they have superhuman strength on Planet Koya Koya thanks to it's weak gravity.
- Fat and Skinny: Uno and Doubt, in that order.
- Minion with an F in Evil: Approximately none of their onscreen schemes works, making them the token punching bags for the heroes.
- Mook Lieutenant: They're shown leading the Gartite Syndicate's lesser mooks.
- Those Two Guys: Borgant's two leading enforcers that are always seen together.
Guillermin
- Ascended Extra: He had a larger role in the remake than the manga or original anime.
- Brutish Bulls: His spaceship is based on a mechanical bull, which he use in an attempt to run over the heroes.
- Challenge Seeker: He desires to challenge the best gunslingers across the galaxy, and took an interest towards Nobita after hearing of the latter's various exploits in defeating the Gartite Corporation's enforcers. Even if it means dying from his own planet detonator in the process.
- The Dreaded: One of the Gartite Corporation's deadliest, most evil and powerful enforcers. Uno and Doubt are both terrified when Borgant informs them he's bringing out "the Great Guillermin".
- The Gunslinger: He's the top marksman of the Gartite Corporation, and serves as a direct counterpart to Nobita.
- Honor Before Reason: Despite knowing fully-well that the detonator is minutes away from blowing Planet Koya Koya into space dust, Guillermin is eager to stay behind and confront Nobita, one-on-one, instead of evacuating like the rest of the Gartite Corporation.
- It's Personal with the Dragon: The climax of the adventure have Nobita and Guillermin facing each other, mano-on-mano, with Nobita determined to take down Guillermin for trying to kill him and all his friends. Meanwhile, the actual Big Bad, Borgant, is halfway from leaving Koya Koya.
- Showdown at High Noon: His final duel against Nobita, where both of them will draw as soon as the light on the detonator hits the top.
- The Stoic: His face shows no expression but a grim, steely, solid scowl, not even blinking a bit as Borgant, Uno and Doubt are celebrating over Guillermin's grand plan to blow up Planet Koya Koya. He did crack a "little" smile when he thought he had won his duel against Nobita.
- Token Competent Minion: Once Nobita and Doraemon realize they have much superior strength on Planet Koya Koya, they easily bulldoze their way through each and every obstacle the Corporation throws at them. It's not until they confront Guillermin that they realize they might have met their match.
- Worthy Opponent: After seeing Nobita gun down multiple of the Gartite Syndicate's lesser minions with ease, Guillermin is more than eager to face Nobita in a one-on-one, mano-to-mano duel, which he gets to at the conclusion of the story.
- You Are Already Dead: Downplayed version, since, well, this being Doraemon nobody can really die onscreen. But his final duel against Nobita have both of them drawing guns at the same time. Nobita staggers a bit after pulling the trigger, as Guillermin gloats a bit… but then he collapses in an unconscious heap, defeated.
