Doraemon: Nobita and the Space Heroes (2015) Timeline Explained – Every Event in Order

Nobita becomes jealous when Suneo shows off his new radio-controlled toy robot Micross at the playground. Feeling outdone, he begs Doraemon to conjure a giant robot that could outshine Suneo's toy. When Doraemon refuses, Nobita storms off and discovers the mechanical orb at the North Pole, which gives him the means to build one.

Foreshadowing: Nobita's jealousy over Suneo's toy earlier in the movie sets the stage for his willingness to use powerful gadgets without fully considering the consequences.

Zanda Cross is a massive robot built by Nobita and Doraemon in a hidden mirror world accessed using Opposite World Entrance Oil on water. They discovered a mechanical orb at the North Pole that could summon robot parts, which they used to assemble the machine. It was controlled remotely using a psychic controller since it lacked its own brain.

Foreshadowing: The mysterious orb found at the North Pole becomes the key to building the robot that later plays a central role in the invasion storyline.

The mirror world is accessed by applying Doraemon's Opposite World Entrance Oil to a calm water surface, creating a portal. Objects and people can pass through, though size limitations apply, Zanda Cross was too large to fit through the portal when it tried to pursue Nobita and Doraemon, causing the portal to collapse and trap the robot army inside.

Foreshadowing: The mirror world serves as both a construction site and later a trap for the invading robot army.

Lilulu is an android from the planet Mechatopia who tracks Zanda Cross (which she calls Judo) to Earth. She is the true owner of the robot, having created it for her homeworld. She initially asks Nobita to keep her presence secret and demands the psychic controller back, but later reveals she was part of a plan to invade Earth on behalf of Mechatopia's robot population.

Foreshadowing: Lilulu's mysterious tracking of the robot from the North Pole hints at her connection to a larger conflict beyond Earth.

Judo is the bowling-ball-sized mechanical orb Nobita discovered at the North Pole. It is actually the mechanical brain meant to pilot Zanda Cross. When Doraemon uses Translation Jelly on it, Judo reveals it has already signaled the robot army to invade Earth. The group later reprograms Judo to ally with them, transforming it into a weapon against the invasion.

Foreshadowing: The orb that seemed like a simple discovery tool turns out to be the key to controlling, and stopping, the robot invasion.

According to Lilulu, robots were created by God on Mechatopia after He gave up on humanity. The robots eventually rebelled against their creators, and in a compromise, they decided to invade Earth to enslave humanity. This backstory explains why Mechatopia's robot army views Earth as their rightful conquest.

Foreshadowing: Lilulu's explanation of Mechatopia's history reveals the ideological foundation behind the invasion plan.

The group creates a trap by using Zanda Cross's signal to lure the robot army into the mirror world through a lake entrance. When the robots discover the world is backwards and empty of humans, they realize the ruse. Meanwhile, Shizuka, Lilulu, and Micross travel back in time to ancient Mechatopia to convince God to rewrite history, which causes the invading robots to vanish from the present.

Foreshadowing: The mirror world that once trapped the robots becomes the setup for the invasion counter-strategy.

• mirror world trap
• time travel strategy

Shizuka, Lilulu, and Micross travel to ancient Mechatopia to plead with God to reprogram the two progenitor robots Amu and Imu, which would rewrite history and prevent the robot rebellion. God agrees but is too weak to complete the process. Lilulu volunteers to finish the reprogramming herself, fully aware this will erase her own existence from history.

Foreshadowing: Lilulu's willingness to sacrifice herself represents the culmination of her character arc from antagonist to ally.

• progenitor robots amu imu

After Lilulu completes the reprogramming in ancient Mechatopia, she fades away from existence while shaking hands with Shizuka. However, the final scene shows Nobita glimpsing Lilulu flying outside his window, interpreting her as an angel. The end credits confirm this when her silhouette is seen soaring into space, waving goodbye to Earth.

Foreshadowing: The bittersweet ending suggests that Lilulu's sacrifice may have granted her a transcendent existence rather than complete erasure.

Doraemon gives sentience and the ability to talk to Micross, Suneo's radio-controlled toy robot, to help in the battle against the robot army. Micross becomes a valuable ally, particularly when it rescues Shizuka by knocking out the injured Lilulu in the mirror world.

Foreshadowing: The once-simple toy becomes an unexpected hero in the final confrontation.

Shizuka, Lilulu, and Micross use Doraemon's time machine to travel to ancient Mechatopia to meet God, the creator of robots. Their goal is to convince Him to reprogram the two original robots Amu and Imu, which would alter Mechatopia's history and prevent the robot rebellion that leads to the invasion of Earth.

Foreshadowing: This time-travel mission is the key to resolving the conflict without conventional warfare.
