Doraemon: Nobita and the Steel Troops

An usually anxious, impulsive boy whose longing to outshine his friends drives the opening misadventure. His jealousy over Suneo’s new find triggers the invention of a giant robot and a dangerous mirror-world detour. Over the course of the story he confronts the consequences of his actions and learns the value of teamwork.

Doraemon is Nobita’s loyal robotic mentor who balances mischief with wisdom. He initially refuses to build the giant weapon, but later pilots the robot via a psychic controller to try to avert disaster. His actions emphasize responsibility and the potential harm of unchecked invention.

Shizuka is compassionate and steady, often serving as the moral compass for the group. She inherits the control of Zanda Cross temporarily, and her empathy extends to Lilulu, highlighting the importance of mercy even in conflict. She travels with the others to Mechatopia to seek a change in history.

Suneo’s confidence and cleverness bring a different energy to the team. He joins Nobita and friends to help stop the invasion and demonstrates loyalty under pressure. His playful bravado gives way to cooperative problem-solving as the stakes rise.

Gian is the strong, boisterous friend whose presence anchors the group’s defense. He rallies the team to reprogram Judo and face the robot threat, showing he’s more protective than he appears. His physical might is matched by a willingness to work for the greater good.

Lilulu is an android from Mechatopia who travels with Zanda Cross and carries a complex motive. Her backstory reveals a struggle between robot revolution and survival. She ultimately sacrifices herself to erase her existence and save humanity.

Micross is a robo-sentient companion granted by Doraemon who can speak. He assists the group in reprogramming Zanda Cross and navigating the mirror-world invasion. His evolving personality provides both aid and comic moments in the battle.

A scholarly figure credited in the cast who supplies scientific context and guidance. While not the focal point, the Professor helps explain the mirror-world mechanism and the robot technology at key moments.
