Uchuyaro Subaru (宇宙野郎昴 Uchūyarō Subaru, lit. Spaceman Subaru) is an Astronaut-Type Humagear. His brother Uchuyaro Raiden is also an Astronaut-Type Humagear.


Subaru was created as a part of the Uchuyaro series at some point of after the launch of Satellite Zea. Ikazuchi (Raiden), being an older Humagear of the same series, acted as Subaru's elder brother and guided him throughout their carrier.

Meeting Aruto Hiden

After Aruto became the CEO of Hiden Intelligence and gained Zero-One Driver, a new activity was added to Subaru and Raiden's job, to reinstall Rise Hopper at Zea after Aruto summoned it on Earth. However, they were irritated by Aruto's reckless usage of the bike, causing them to install it on Zea several times and consuming a lot of fuel and so they headed to Hiden Intelligence's HQ to talk to him. We are the Astronaut Brothers!

Family Reunion

While he was on his way to continue his duty, He saw Raiden who just got revived in a very long time after his destruction. Later, Subaru unattached the Breaking Mammoth from the corrupted Zea, Raiden use Breaking Mammoth Jet Mode to destroy Ark and the corrupted Zea once for all. Thou, Take Thine Neighbor's Hand!

Although Subaru was not seen again after the destruction of Ark and Zea, Subaru likely return to his duty again with Raiden. The Future of Each


Subaru is the opposite of Raiden. While Raiden has a aggressive, passionate and hotblooded personality, Subaru was much more calm, such as when they're putting the Rise Hopper back to Zea and when they stormed Aruto's office, Aruto apologizes and Subaru forgives Aruto, but Raiden continues to berate Aruto. 


  • Cognitive Learning: Subaru can learn new experiences and act according to what he processes from them.
  • Connection with Zea: Being the maintenance head of Zea, Subaru can access Zea from Earth and activate Zat like Izu does.The End of Each


  • Uchuyaro Raiden: Raiden is Subaru's brother and fellow Astronaut-Type Humagear, who is then revealed to have been a spy for MetsubouJinrai.net named Ikazuchi. He appeared to have disowned him upon this discovery, but after achieving Singularity, Subaru began to mourn Raiden upon realizing his destruction. However, while he was on his way to continue his duty, he saw Raiden who just got revived in a very long time after his destruction and later help him destroy Ark once for all.
