Doraemon: Nobita in the Wan-Nyan Spacetime Odyssey (2004) Timeline Explained – Every Event in Order

Old Ichi enters the time machine hoping to meet the person who once gave him a kendama. This is a personal quest to reunite with someone significant from his past. The kendama serves as a sentimental link to his original owner, driving his motivation to travel through time.

Foreshadowing: The kendama connection is established early when Nobita names the dog Ichi after hearing a bark that sounds like 'ichi' while playing with his own kendama.

A sudden time-space anomaly disrupts the time machine's normal operation. Instead of traveling forward to meet his intended person, the malfunction causes Old Ichi to regress backward in time, reverting to infancy. This accidental time travel is what leads to him being discovered by the researcher cat.

Foreshadowing: The time-space anomaly that disrupts Ichi's journey foreshadows the similar anomalies that later affect Nobita and the animals.

The Ray of Evolution was supposed to send the animals 300 million years into the past using the time machine. However, another time-space anomaly occurs, propelling them 1,000 years into the future instead. This unexpected shift is what leads to the discovery of the evolved canine and feline society.

Foreshadowing: The opening scene's time-space anomaly establishes the pattern that will repeat throughout the film.

The animals used the Ray of Evolution repeatedly over centuries. This technology accelerated their evolution dramatically, allowing them to develop intelligence, language, and complex social structures within just a thousand years. The continuous use of the ray is what transformed them from simple animals into the futuristic society Nobita encounters.

Foreshadowing: The desperate need to save the abandoned animals sets the stage for the risky use of the Ray of Evolution.

Hachi is the elderly dog Ichi from the timeline's end, not the beginning. After living in the evolved society for centuries, he traveled back in time as a young adult, becoming the leader of the teen thieves. When Nobita rescues him from drowning underwater, the experience triggers his lost memories, revealing his true identity as the Ichi Nobita met in the present.

Foreshadowing: Nobita's suspicion that Hachi resembles Ichi, despite the centuries between them, plants the seeds for this revelation.

Noradium is a rare material essential for building evacuation spacecraft. The government needs it to create a fleet of ships capable of escaping the asteroid impact. Nekojara steals the Noradium to power his revenge scheme, while the group ultimately recovers a Nobita-shaped statue made of pure Noradium to present to the authorities.

Foreshadowing: The Noradium statue becomes crucial in convincing the government to evacuate everyone.

Nekojara wants revenge on humans for abandoning animals, which he views as a betrayal of the bond between humans and their pets. He plans to use the Ray of Evolution's devolve function to send humanity back to primitive times, punishing them for this abandonment. His ancestor Zubu wrote a prophecy about this very event.

Foreshadowing: The theme of abandoned animals runs throughout the film, beginning with the deforestation scene.

Zubu, the cat who raised Ichi as a researcher, authored a prophecy about the Ray of Evolution and its potential misuse. This prophecy foretells of a time when someone would exploit the devolve function to punish humanity. Nekojara uses this prophecy to justify his revenge plot, believing he is fulfilling destiny.

Foreshadowing: The presence of Zubu as a stray cat in the present connects to her role as a historical figure in the future.

Ichi (both as the elderly dog in the opening and as Hachi in the future) hid a statue made entirely of pure Noradium in the shape of Nobita. This statue serves as proof of the children's journey and their connection to the animals. Presenting it to the government validates their story and helps secure the evacuation effort.

Foreshadowing: Ichi's bond with Nobita, formed through their kendama play sessions, explains why he would create such a statue.

After recovering the Noradium, the government completes several evacuation spacecraft. Everyone, including Nekojara and his minions, escapes the city just before the asteroid cluster impacts and destroys it. The successful evacuation ensures no lives are lost despite the city's destruction.

Foreshadowing: The government facility where Noradium is stored was established specifically to handle such cosmic threats.

The Ray of Evolution is a device capable of accelerating evolution. The children use it to send animals millions of years into the past, allowing them to evolve naturally before complex life existed on Earth. Nekojara attempts to use its reverse function, called devolve, to regress humanity to primitive states as punishment for abandoning animals.

Foreshadowing: The desperate need to save endangered animals leads to the risky decision to use this powerful technology.

Nobita forms a genuine emotional bond with Ichi during their time together. The promise to return reflects his determination to honor that friendship and go back to check on Ichi's welfare in the prehistoric era. This promise drives much of his motivation throughout the adventure.

Foreshadowing: Nobita's compassionate nature is established early when he rescues the drowning stray dog.

The animals, including Ichi and the other dogs and cats, evacuate along with the humans aboard the spacecraft. The film shows them departing the city together with Nobita and his friends, saying farewell moments before the asteroid destroys the city. In the post-credits scene, the group returns to the present and says final goodbyes.

Foreshadowing: The collaborative evacuation plan demonstrates the reconciliation between humans and animals.

Doraemon is forced to fix the Ray of Evolution because Nekojara threatens Shami, a cat idol who serves as his minion. The threat to Shami's safety compels Doraemon to cooperate, though he eventually breaks free and prevents the plan from succeeding when Shami turns against Nekojara.

Foreshadowing: Shami's role as a celebrity in the future hints at her connection to the technology.
