Characters introduced in Doraemon: Nobita and the Galaxy Super-express.
Galaxy Express
A galaxy-faring train capable of carrying hundreds and hundreds of passengers across alien worlds, before arriving in a mystery grand destination.The Conductor
"At your service!"
A small and cuddly alien who's in charge of the train's services, facilities, and general safety of the passengers and crew.
- Ambiguous Robots: The Doraemon wiki and most external sources said the conductor is a robot, but it's never made clear within the story itself.
- Big Damn Heroes: While Doraemon, Nobita, Gian and Shizuka gets ambushed by enemies led by possessed!Suneo, the Conductor managed to save Baum from the same fate by showing him a hidden underground passage. Later on the two of them saves Nobita and gang by knocking out possessed!Suneo.
- Cute Oversized Sleeves: The Super-Express' conductor is a short, cuddly midget alien (or robot, it's not really clear) who wears a human-sized uniform. As such, his arms are tucked inside both sleeves in every scene, which flops around comically whenever he walks.
- Everyone Calls Him "Barkeep": His full name is never revealed in the film. Even the credits refer to him as the "Galaxy Super Express Train Conductor".
- It's All My Fault: After the first train crashes on an abandoned mining planet after having its fuel sabotaged by possessed!Ashton, the Conductor blames himself over the issue. Baum, Nobita and the other main characters tells him it's not, he couldn't have foreseen it either.
- Never Bareheaded: The Conductor never lose his cap, no matter what, even when he's atop the Super-Express during a high-speed chase against raiders or when the train starts crashing into an abandoned planet and throwing everyone off their feet.
- Nice Guy: Friendly, affable, polite, and sees to it that the guests of the galaxy express have all their accomodations properly tended.
- Robot Buddy: Assuming that the conductor is a robot, then he's this to the passengers.
- Token Non-Human: The only alien / robot / non-human member of the heroes, besides Doraemon of course.
Baum
"Mr. Baum from the 22nd-Century News Agency, nice to meet you."
A journalist aboard the galaxy express, seeking the latest scoop regarding the mystery destination before getting dragged into the Yadori invasion.
- Big Fun: A huge man, but certainly a helpful and friendly member of the cast.
- Intrepid Reporter: He goes in for the scoop after finding out about the Yadori invasion, with his reports proving useful for the Time Patrol to be alert of future Yadori activity.
- Nice Guy: A pretty helpful and friendly member.
- Token Adult: He's the only adult member of the main characters (discounting the Conductor who's presumably an adult).
Aston, Don and Jane
From L - R, Aston, Don and Jane
A trio of 22nd Century tourists who made a rather bad first impression with the gang after Nobita tries greeting them, only for them to laugh at Nobita and everyone else for being "cavemen from two centuries ago".
- Adaptational Badass: Don and Jane doesn't partake in the final battle in the original manga, but they do in it's anime adaptation.
- Adaptational Nice Guy: The anime movie have the trio apologizing to Nobita and gang for being dicks to them during the tour, something that the manga didn't include.
- Ascended Extra: They have slightly more scenes in the anime (compared to the manga), including having Don and Jane help out in the final battle.
- Brainwashed and Crazy: Ashton completely loses it after getting possessed by a Yadori, where he then Drives Like Crazy around an asteroid field (nearly crashing a few times) before kicking Don and Jane out and bailing his former friends. He goes back to normal by the end of the story.
- Break the Haughty: Ashton, for most of his screen time is The Ace of the trio, and gleefully shows it off in front of his friends as well. And then he's possessed by the aliens and goes crazy and momentarily becomes the scapegoat when Don and Jane blames him for abandoning them on an asteroid. He's a lot less smug in his final scene.
- Chekhov's Gunman: They appear briefly to make fun of Nobita and gang before leaving, only for Don and Jane to reappear in the mining planet's underground tunnels to show Gian (who's lost underground just like them) the second express train crucial for the heroes to use for their escape.
- Disproportionate Retribution: They're kind of rude to Nobita and the others, but that doesn't justify having Ashton getting possessed and becoming a minion of the Yadori aliens, or Don and Jane getting stranded on a dead planet and nearly dying of thirst.
- The Rival: There's a brief rivalry between Nobita and Ashton when they're on the Planet of Cowboys' shooting range, both of them trying to out-excel each other's Improbable Aiming Skills. Ashton seems to have won by hitting five out of six targets, with Nobita hitting only one, but then Nobita reveals the one can he shot at contains six bullets.
- Two Guys and a Girl: Ashton and Don are the guys, and Jane is the girl.
- Villain-Possessed Bystander: Ashton, after getting hijacked by one of the Yadori drones and leading them to take over the Express.
Villains
The Yadori Aliens
A bunch of Yadori drones.
Let's play "Find the Boss".
- Accidental Pervert: One of the random Yadori sneaks into the Super Express' bathroom, just as Shizuka is in the middle of taking her bath (what else?). While it has intentions of possessing Shizuka, on the other hand Shizuka mistaken the UFO to be a voyeur and sprays it with soap, accidentally killing it and later revealing the Yadori's major weakness to the rest of the heroes.
- Aliens Are Bastards: Discounting Doraemon: Nobita's Little Space War (which has good and bad aliens on both fronts), the Yadoris are the first completely malevolent alien race in the Long Stories series.
- Big Bad: The Yadori Emperor who leads the other aliens is the biggest threat of the adventure this time.
- Body Surf: Each individual Yadori can possess only one victim at a time, as seen later in the adventure when the one possessing Suneo then skips on Nobita instead. After Nobita gets doused with the soap solution and recovers, Suneo then wakes up, back to normal too.
- Clipped-Wing Angel: Basically what happens if they're infecting a human or humanoid body. Being inside another body doesn't remove their weakness towards soap, and it makes them even larger and easier targets.
- Flying Saucer: They pilot flying saucers the size of toys as transport, at least until they found a host.
- Gold-Colored Superiority: The Yadori Emperor pilots a golden saucer, unlike his minions.
- Nice Job Fixing It, Villain: The one random Yadori who tried possessing Shizuka who's in the middle of her bath unintentionally reveals his entire race's major weakness to the heroes.
- It Can Think: The Yadori aliens, despite being mere parasitic life-forms, are completely sentient. Their leader in particular can pilot giant robots.
- Manipulative Bastard: The first wave of Yadori infects the staff of an intergalactic theme park planet, uses its communication system to sabotage facilities on other surrounding theme park worlds to prevent guests from leaving, and traps the Super Express on it with the intentions of infecting everyone on board. Most Yadori, after possessing human bodies (like the one controlling Suneo) will pretend to be still humans in order to trick other victims to be captured alive for infection.
- Meaningful Name: They're named after the yadokari or hermit crab.
- Meat Puppet: What their victims become after being possessed.
- Mook Mobile: Their mini-saucers serve this purpose to individual Yadori aliens.
- Puppeteer Parasite: Their modus operandi have them infecting humans, humanoid aliens and assorted living creatures, using their infected victims as puppets.
- Take Over the World: Their goal is to take over entire populations of planets by infecting their victims, starting with the entire theme park and the Galaxy Express' passengers, staff and crew.
- That Man Is Dead: When possessed!Suneo reveals his true identity to Nobita and gang after capturing them alive.Possessed!Suneo: I'm not Suneo anymore. You can call me Parasite 006.
- There Is No Kill Like Overkill: After the Yadori Emperor gets shot down by Nobita and falls on the ground, his giant fifty-foot robot, now without a pilot, falls on him.
- Underestimating Badassery: The Yadori Emperor assumes Nobita is a helpless weakling who's frozen with fear at the sight of the giant robot, and gets out from within the safety of his mecha to infect Nobita from up close. Turns out Nobita was Playing Possum and quickly blasts the Emperor out of the sky.
- Villain: Exit, Stage Left: The rest of the Yadori turns around and flees after their Emperor is defeated.
- The Virus: What these microscopic-sized alien invaders amounts to.
- Weaksauce Weakness: They're highly vulnerable to soap solution. Even if they're inhabiting a human / humanoid body, once their skin or face is doused with soap, they shrivel and drops out of their victims, who then recovers shortly afterwards. The Yadori Emperor gets around this issue by controlling a gigantic robot from the inside to assault the heroes at the end.
