Doraemon: Nobita's Treasure Island

An adventure to the farthest edge of the ocean.

Doraemon: Nobita's Treasure Island is the 38th movie of the Long Runners Doraemon franchise.

A mysterious island is spotted outside Tokyo's bay during the summer break, prompting Nobita to suggest his friends to go explore it, disregarding his parents' wish for him to finish his homework first before embarking on his adventure. After a day of voyage, the gang finally reach the island, only to be attacked by a band of pirates who kidnap Shizuka after the heated battle. Nobita and the rest are soon met by Flock, a stranded boy who claims to have escape from the ship and its Captain, Silver. What is the mysterious Captain truly after, and what's the dark truth that lies within this "Treasure Island"?

Tropes used in Doraemon: Nobita's Treasure Island include:

• An Aesop:
  • Before saying out anything, tries putting yourself in other people's shoes and thinks of how they feel first once they hear it first.
  • Even adults can make mistake.
  • Communication between family and friends is important.
  • No matter how harsh life is, and even though we'll never know that our future will be good or bad, we must always have a hope to live fore it.
• Apocalypse How: Class 6. In the future (year 2295) that John went to, the world has become a ruin of itself with no life remains.
• Arc Words: "There is always something far more important than treasures."
• Call Back: To "the Night Before Nobita's Wedding" of all things: Fiona's last wish is for John to raise their children to be able to experience other people's sadness and joy like he always does, as it's what made her fell in love with him in the first place, the exact same reason that Shizuka's father affirmed that Nobita is the best person for Shizuka to spend her life with, for that he knows how to make people both sad and happy alongside him.
• Composite Character: In this movie, Captain Silver is a composite character of the titular character and the novel's protagonist's father.
• Cyborg: Gaga, Vivi's partner, is shown to be capable of extending his mechanical hansd indefinitely which he combines with his markmanship for maximum effectiveness.
• Dark Action Girl: Vivi, Captain Silver's right hand woman, is skilled in swordsmanship and serves as the gang's adversary throughout the movie alongside her partner Gaga. Her being able to easily block off Doramon's Air Cannon (one of his most powerful offensive gadgets) by simply slicing the air pressure shows how dangerous and intelligent she is.
• Heel Realization
  • Nobita gets one when he realizes that he was being too selfish for not understanding Nobisuke's words and instead thinking that his father hated him and what he wanted to do after hearing an Ironic Echo from Flock.
  • Flock gets one toward the end of the movie when he realizes how hurt John must be when he told John that he didn't see him as his father anymore and apologizes to him in tears.
• Identical Stranger: Sarah looks exactly like Shizuka, except for hair and eye color.
• Karma Houdini: Despite their actions still falling under the definition of Time Criminal, none of the bad guys get punished/arrested by the Time Patrol at the end of the story.
• Mood Whiplash: The gang's voyage to the Treasure Island started off safe and secure, but the action and drama quickly kick in the moment Vivi and Gaga led their troop abroad their ship and kidnap Shizuka.
• Punch Clock Villain: Vivi, Gaga, and their troop are all amiciable and friendly when outside their job, and the major reason that they're very serious in battle against the gang primarily comes from the fear of their dreaded superior, Silver.
• Self-Fulfilling Prophecy: Though not stated in the story, Silver (John)'s plan to syphon all the energy from the earth in order for him and his crew to flee the planet in order to avoid the 2295's dystopia is implied to be one of its possible causes in itself.
• Strong Family Resemblance: Flock and Sarah both took after their mother Fiona more than their father John.
• Shout Out: The movie notably is more similar to Treasure Planet than the original novel, from the sci-fi and futuristic theme down to the core plot of Flock (Jim Hawkins)'s antagonistic relationship with Silver (Leland), not to mention the similar role of Nobita and B.E.N.
• Walking Shirtless Scene: The boys and Flock spend a quarter of the movie only in their shorts/pants.
• Younger Than They Look: Flashbacks suggests that Silver(John)'s age shouldn't be anything more than 40s. This is justified as he looks the way he is because he became so stressed from continueing his wife's project and from losing all the hope of the Earth's future after seeing the apocalyptic world of 2295.
