Planet Esmeralda is a vibrant world known for its precious emeralds, which possess immense energy properties, and for its ruling royal family. It functions as a central setting in the film and becomes a key target because the power of its emeralds can fuel conquest.

The Land of Light refers to Nebula M78, the home world of the Ultra beings. It functions as a sanctuary for Ultraman and his allies but is constantly threatened by dark forces such as Kaiser Belial. Belial's earlier clash with Zero and other Ultramen on this planet is part of why his return in this film carries such weight.

The 2-D Planet of Mirrors is a surreal world where reality itself is distorted. It harbors secrets that become crucial for the fight against evil in the film. Its otherworldly nature makes it a unique setting compared to the more conventional worlds of Planet Esmeralda and the Land of Light.

Run, voiced by Yû Koyanagi, is a brave young man who shows unwavering loyalty to his brother, Nao. Throughout the film, he evolves from being a mere survivor into an active participant in the battle against Belial.

The film centers on three major themes: heroism, friendship, and the pursuit of power. Heroism is expressed through Zero and his allies' willingness to sacrifice for others, friendship drives the team's unity against overwhelming odds, and the quest for power is explored through both Belial's destructive ambition and Zero's transformation into Ultimate Zero. Together, these themes shape the film's classic light-versus-darkness narrative.

The film portrays heroism as a combination of bravery, selflessness, and the willingness to make ultimate sacrifices. Ultraman Zero repeatedly puts himself in danger to protect others, and supporting characters like Princess Emerana also step forward at great personal cost. The story suggests that true heroism requires resilience in the face of impossible odds rather than raw power alone.

The film contrasts two uses of power: Kaiser Belial's destructive ambition to conquer and the heroes' use of power to protect. The emeralds of Planet Esmeralda symbolize how energy sources can fuel conflict when pursued selfishly. Zero's transformation into Ultimate Zero ultimately shows that power, when wielded for good, becomes a force for salvation rather than domination.

Standing against him is Ultraman Zero, who must rise to meet his father Ultra Seven's legacy and rally allies from multiple planets.
