Utsusemimaru

"The Thundering Brave, Kyoryu Gold is here!"

- Kyoryu Gold's role call

"Vanquishing evil in the name of heaven! Prepare for wildness!"

- Utsusemimaru's word before fighting his opponent

Utsusemimaru (空蝉丸), nicknamed "Utchi" (ウッチー), is a Sengoku Period-era Samurai who was trapped in the sentient Raging Knight Dogold armor for 400 years. He assumes the role of Kyoryu Gold (キョウリュウゴールド) with his partner, the Zyudenryu Pteragordon.

400 Years Ago
During the Sengoku Period, Utsusemimaru had served under a lord named Moshinosuke Iwaizumi, who had made the future Kyoryuger a samurai despite his background as a commoner and a ronin. When the Deboss Army attacked Japan in an undisclosed time either before or after Utsusemimaru bested Zyudenryu Pteragordon, Torin had asked Iwaisumimonosuke for Utsusemimaru's power to fend off the Deboss Army, which was granted.

During one fateful battle with the Deboss Army, Utsusemimaru saw a Debo Monster with a carp banner kidnap a child on the battlefield, to which Utsusemimaru had foiled. Undoing his transformation, he tried to stir the child, unknowing until the last second of the ingenious trap the Deboss Army had made for him, with the boy actually a Zorima in disguise about to cut him down. However, Moshinosuke Iwaizumi threw himself to take the blow meant for Utsusemimaru, grievously wounding the lord. Slaying the Zorima out of rage, a distraught Utsusemimaru watched on as Moshinosuke Iwaizumi passed away in his arms minutes later after the attack after leaving some final words.

Without their lord, Moshinosuke Iwaizumi's remaining forces were later killed off by the Deboss Army, including Utsusemimaru's human partner Jurota.

With Torin captured and about to be executed by Dogold, a vengeful Utsusemimaru changed into Kyoryu Gold and saved Torin's life. However, Dogold attempts to escape into a dimensional portal and Utsusemimaru gives chase, only to be absorbed by the armor itself. .

Present Day
After the fateful day four centuries ago, Dogold returns, but not as Kyoryu Gold, which causes Torin to question what happened to Utsusemimaru. After a heated battle, Kyoryu Red breaks Dogold's mask, revealing the face of Utsusemimaru.

With the quick thinking of Amy, Torin, and Ramirez, Utsusemimaru was able to escape from Dogold's armor and transforms into Kyoryu Gold, free from his centuries-old spell, and defeats the remaining Knights and the remaining Cabrima, showing the Kyoryugers why he is nicknamed the Thundering Brave (雷鳴の勇者).

After the fight, the other Kyoryugers approach him and cancel their transformation, making Utsusemimaru remember his slain lord Moshinosuke Iwaizumi when he saw Daigo's face. Remembering his last words that his kindness would get him killed, Utsusemimaru had constructed a mask of cold aloofness and brushed off the Kyoryugers.

Utsusemimaru still helped the the team whenever he could, though he retained his coldness. But the continuation of the cold mask eventually made him feel exceptionally guilty, and was soon discovered of this by Amy. After the Horned Brave shared an ice cream cone with him, the samurai confessed his past and why he created a mask of coldness.

Utsusemimaru joined the other five Kyoryugers to get to Deboss but stopped to prevent Raging Knight Dogold and Hateful Knight Endorf from stopping the rest of the team. Utsusemimaru fought the two knights for long time but was caught by Endorf. When he is seemingly about to be killed by Dogold, Endorf was slashed instead. Dogold and Utsusemimaru makes a temporary alliance and when their attacks don't work, Dogold becomes the armor of Utsusemimaru and combines their attacks and defeats Endorf. After the battle with Endorf ends, Dogold challenges Utsusemimaru to a final battle with Dogold being truly destroyed by Utsusemimaru. He then afterwards faints and falls to the ground. He was later revived by his teammates melody.

Personality
While initially appearing to be cold and calm, Utsusemimaru is actually a very caring and comforting person.

Another thing about Utchy noted by both Amy and Debo Honenukky, the out-of-time samurai is quite bashful, being awkward around women.

Abilities
He has proven himself to be better at shooting than Ian, strikes harder with his kicks than Amy, has a more perfect swordsmanship than Souji, and is even physically stronger than Nobuharu, thanks to him overpowering Debo Honenukky when the other Kyoryugers could not.

He understands very little of the English language, as the only English words he can understand are "Perfect" (thanks to Amy), "King" (strangely), and the transformation words needed for the Gabrichanger.

While being possessed by the Raging Knight Dogold, Utsusemimaru is forced to wear Dogold's armor, and armed with Kenka Jōtō (喧嘩上刀) seven-branched sword.

During their final confrontation, Utsusuemimaru very briefly wore Dogold's armor once again in a temporary team-up against Resentful Knight Endolf. This time, however, he was not controlled but instead worked in conjunction with Dogold while wielding both his Zandar Thunder and Dogold's Kenka Jōtō, combining their techniques to destroy Endolf.
