Characters from Doraemon: Nobita and the Green Giant Legend.
Kibō
"Ki, ki, ki!"
A sapling Nobita found in a dumpster and took back home with intentions of planting, only for Tamako to forbid because their garden is already cramped. Doraemon, on the other hand, had other ideas, specifically involving giving the sapling a Life Elixir turning it into a sentient, living plant that the Nobi household decide to adopt, naming him "Kibō".- Accessory-Wearing Cartoon Animal: He wears shoes given by Nobita, even though his root-like legs couldn't possibly fit in them. Somehow.
- Adaptational Attractiveness: His original form in "Goodbye, Kibō!", is a flower with a face, and still appears closer to a plant than an organic being. This Kibō on the other hand gains more human-like features, including a face akin to a human child, and a more humanoid body. Compare and contrast (left is the original, right is the remake)
. - Adaptational Nonsapience: Kibō from "Goodbye, Kibō!" gains the ability to speak after being taught by Doraemon and Nobita, even conversing fluently with the other major characters. This version of Kibō on the other hand doesn't have any abilities of speech until late into the film, after the climax.
- Almost Dead Guy: Narrowly dehydrates halfway into the film, while everyone's trapped in a series of tunnels under Planet Green's surface, too far from any source of water. Thankfully, Gian volunteered to collect water after the gang is informed of an underwater spring nearby, arriving just in time before Kibō succumbs.
- Alternate Self: Is an alternate version of the titular character from the manga short, "Goodbye, Kibō!". Note that the OG Kibō had previously appeared in Doraemon: Nobita and the Kingdom of Clouds playing an important role.
- Apocalypse Maiden: It turns out Kibō is the last component for growing the World Tree on Tokyo, which will completely terraform earth's surface into one similar to Planet Green's, with plants coming to life and replacing humans and animals. Nobita and gang in the finale must race against time to prevent that from happening.
- Become a Real Boy: An element absent in the manga short where the movie is adapted from, much of Kibō's story arc have him growing from a sapling to a sentient tree-boy and finally embracing an identity as a true member of the Planet Green plant population in the ending.
- Break the Cutie: The moment he's captured alive and forcibly converted into a bioweapon meant for destroying earth, a process which is as tortorous and as painful as it sounds.
- Bucket Helmet: Shortly after wandering off from the Nobi household, Kibō befriends a little girl who's cooling off in an outdoor pool, and gets a plastic beach bucket as a "souvenir" which he uses as an impromtu cap.
- Children Are Innocent: Even sentient plant children. Sadly little does Kibō know the danger he's facing on Planet Green.
- Constantly Curious: Kibō loves exploring the world, though it's justified since he's a tree stalk recently bestowed life by Doraemon's gadgets.
- The Cutie: Looks and behaves like an adorable, hyperactive child.
- Everyone's Baby Brother: Having Kibō around really drives out the brotherly and sisterly instincts among the gang, with everyone rushing to protect the plant-child from every danger imaginable.
- The Gadfly: Towards Princess Lire, at first. He repeatedly trolls and clings onto her, despite her repeated attempts to knock him off. His attitude mellows out after a while though.
- Meaningful Name: Kibō is derived from the Japanese words, "Ki" (lit. "tree") and "Bo" (lit. "boy"). Additinally, when combined, "Kibō" also reads as "hope".
- Plant Hair: Has a bunch of leaves growing all over his scalp in place of hair.
- Pokémon Speak: He vocabulary consists of him saying "Ki, ki, ki!" repeatedly, so Nobita decides to name him Kibō.
- Suddenly Speaking: He gains the ability of speech in his final scene, after spending the entire film conversing with Pokémon Speak.
Princess Lire
Her royal highness addressing her subjects.
The princess of Planet Green, who's constantly tired of life in the palace and desires to explore the world outside.
- Defrosting Ice Queen: Begins as a haughty, snooty princess archetype who looks down on Kibō as well as Kibō's earthling friends, until she got to know them better. She eventually begin accepting these "commoners" as friends.
- Fiery Redhead: She's a redhead and the feistiest, most active character in the entire film.
- Pimped-Out Dress: The regal blouse she wears when making a speech to her fellow plant-people. It's oversized, puffy, cumbersome, and even the princess herself looks uncomfortable walking around in it.
- Rebellious Princess: One who repeatedly runs away from her palace home and shirks her duty to her people, though she does mellow out later on.
Shirah
The grand vizier, advisor of the Planet Green royal family, and supervisor of their World Tree.
- Ascended Extra: In "Goodbye, Kibō!" he's just an enforcer for the plant aliens; he's promoted to becoming the leader and main antagonist of the picture.
- Big Guy, Little Guy: He's the little guy who stood up to his lackey Baruna's waist.
- Big Ol' Eyebrows: His gigantic, curvy white brows really sticks out on his face.
- Heel Realization: After his plans blew up in his face (see one line below) and was saved by Doraemon, Nobita, and the others. He then decide to cancel the planned apocalypse and give humans a second chance to preserve the natural environment on earth. Jii showing the devastated area around Planet Green's capital helped as well."I never thought... I'd be saved by humans."
- Hoist by His Own Petard: Part of his plans involve using Kibō to grow a second World Tree on the plant-covered Tokyo, to give life and sentience on plants, only for Kibō to grow rapidly beyond his control and swallow him alive. Shirah was ultimately saved by Doraemon and gang from getting crushed by his own bio-weapon and realize there's still good in earthlings, after all.
- Meaningful Name: His name can be a play on the word "Shinrabanshō (森羅万象)" which means "all things in nature".
- Named by the Adaptation: He doesn't have a name in "Goodbye, Kibō!".
- Parental Substitute: To the princess.
- Well-Intentioned Extremist: His reasons for dropping the green nuke on earth is to save his non-sentient plant brethren from other planets, driven by the polluted state earth was in and the massive amount of deforestation inflicted on our world.
Baruna
Shirah's eggplant lackey and second-in-command.
- Big Guy, Little Guy: Shares this dynamic with his boss, Shira, who's the little guy that stood around his waist.
- The Brute: Carries out his boss' orders, including hunting down Nobita and gang after discovering the presence of humans on Planet Green.
- The Dragon: The direct subordinate of Shirah.
- Minion with an F in Evil: He might be Shirah's second-in-command, but he seems pretty chill and friendly toward everyone, including the gang when he tries to capture them.
- Shock and Awe: Downplayed, but he can release weak jolts of static electricity from his hands, which knocks out the baby-sized Kibō. Doesn't work on the human characters though.
- Mook Lieutenant: Commands a bunch of giant tree-men security guards.
Tama, and the Underground Plant Tribe
Tama is the tallest one.
Tama's family.
A second race of plant aliens living underneath Planet Green's core, which the gang stumbles upon after fleeing from their cell.
- Children Are Innocent: Just like Kibō, the moment Tama meets the earthlings he's immediately interested in making friends.
- Identical Stranger: One of the citizens of the underground tribe is a huge plant alien named Moya, who looks like an exact duplicate of Gian, save for his green skin. Which leads to Tama mistaking Gian as Moya when they met for the first time.
- Nice Guy: Tama is the friendliest of the bunch, easily getting along with the gang after they met for the first time.
- Plant Hair: Their entire tribe have mossy hair.
- Small, Secluded World: The underground tribe is completely cut off from the surface, and their lifestyle is far more rural and free of technology, thanks to their village being hidden deep under the surface. None of them have desires of going to the surface either, being content in their simple lives.
Jii
Jii, the elder of the tribe.
The village elder that leads the underground tribe.
- The Faceless: His true face under his mushroom cap is never revealed in the film.
- Gag Nose: Part of his very few discernible facial feature.
- Mushroom Man: Jii, the village's elder, is a giant mushroom alien.
- The Pigpen: He's almost always covered by a swarm of gnats. Truth in Television - he's based on a Stinkhorn shroom which can smell really bad.
