Movie
Description
Gō Kurumada is a fifth-grade student in Class 5-1 at Takatomi Elementary and the primary pilot of Drive Head 01 Sonic Interceptor, later upgraded to Drive Head 01 Mk-II Cyclone Interceptor. He is the only child of Mobile Rescue Police chief engineer Jō Kurumada and Kumiko Kurumada. His deceased grandfather, Jōtarō Kurumada, worked on the Drive Head project, and his consciousness was later discovered within the Evil AI's robot Pit.

Gō has spiked blue hair and teal eyes. He typically wears a red shirt, blue vest, and tan pants. His pilot uniform consists of a blue jacket with a black collar, white shoulder stripes, black underarm stripes, and a "DH" badge, paired with blue pants featuring white knee accents and white boots. His personality is enthusiastic, loyal, and strongly driven by justice. He maintains an optimistic, trusting outlook, believing in people's inherent goodness and rarely losing heart, though he can be reckless and single-minded. A key ability is his photographic memory, enabling rapid situational analysis during rescues.

His family relationships are close, especially with his energetic, quick-thinking father whom he resembles. He deeply admires his grandfather's legacy, which becomes pivotal when Jōtarō's consciousness in Pit explains why the Drive Gear selects children with pure hearts. At school, Gō plays soccer and is friends with classmates Hiroaki and Kenichi. His relationship with Taiga Yagura evolves from initial distance to a close, competitive friendship after mutual rescues and shared experiences, like Gō accidentally eating Taiga's prized SyoriSyori ice cream during a geothermal plant incident. Gō harbors a crush on classmate Kasumi Haruno, who admires Sonic Interceptor's pilot without knowing it's him. Mobile Rescue Police regulations forbid disclosure, creating tension. This intensifies when Kasumi accidentally enters headquarters and nearly discovers his secret; Gō maintains the ruse to protect her and the organization.

Gō's journey as a Drive Head driver begins when he hears a "calling" from the Drive Gear during a chemical plant fire. With a 99.9% compatibility rate, he successfully pilots Sonic Interceptor to rescue civilians, leading to his recruitment. Early missions include apprehending robbers, stopping a runaway monorail carrying Kasumi, and rescuing a dog named Axel, who becomes the team's pet. Key challenges include mastering Synchro Fusion—combining his Drive Head with Support Vehicles like the Sonic Jet—initially hindered by his rapid perception outpacing teammates. He overcomes this during a plane rescue involving actor Harrisen Ford.

Technological upgrades and battles mark his progression. After Sonic Interceptor is severely damaged by Dr. Karigari's Walker Vehicle, Gō pilots its successor, Cyclone Interceptor, equipped with enhanced weaponry like the AM516 Magnum sniper rifle and a laser blade. He later achieves new Synchro Fusions, such as Mach Shooting Star with Blitz Formula and Jet Striker with Blitz Jet Fighter, to counter Karigari's weather-manipulation device and maritime threats. The Evil AI emerges as a persistent antagonist, causing disasters like electromagnetic storms and hijacking the Mobile Rescue Police base. During the climax, Gō infiltrates the underground Tower of Babel to confront the AI's origin, Ark, guided by Mikoto Ishino using the Cyber Eye Unit. The revelation of his grandfather's consciousness within Pit underscores the theme that only pure-hearted children can pilot Drive Heads.

In the web series and film, Gō continues battling the Evil AI, now embodied as Terra. He participates in rescues during electromagnetic storms and collaborates with Shun Kuroeda of the Mobile Assault Police. The film includes a crossover with Shinkalion, though Gō's role focuses on resolving the AI threat. His development culminates in reconciling his dual identity and responsibilities, epitomized when he rescues a cat in the finale—mirroring his first rescue of Axel.
