Professor Han is a Dinosaur Empire scientist who succeeds Director Galeli as lead developer of Mechasaurus units. He knows Kamui Sho's secret identity as the previous Emperor Gore's offspring and selectively shares this fact with the Getter Team, despite the Empire's later plans to betray its human allies.

Physically, he stands tall as a dinosaur man with reptilian facial features, including a distinctive nose, beady eyes, and visible facial hair like eyebrows and a beard. His appearance lacks the imposing demeanor common among high-ranking Empire figures, aligning instead with his gentler personality. He consistently secures his cloak with shoulder pads.

Unlike many in the Dinosaur Empire, he lacks intense hatred toward humanity or a strong drive for battle. His primary motivation is ensuring his people's survival, leading him to enter an Enemy Mine scenario where the Empire temporarily allies with the Saotome Institute against the Andromeda Stellaration. He demonstrates genuine concern for Kamui Sho's well-being, guided by their shared history.

His technical expertise includes advanced robotic engineering, enabling him to integrate Dinosaur Empire and Saotome Institute technology to create hybrid units like the Gettersaurus. He also provides navigational guidance through hazardous environments like the Zone for both human and dinosaur forces. During the alliance, he facilitates coordination between former adversaries, reflecting his pragmatic approach to interspecies cooperation.

His narrative function centers around supporting Kamui's character development and enabling temporary tactical alliances. His ultimate fate remains undocumented.
