Yamato Kazakiri is a young zoologist with empathy for humans and animals alike. During his childhood, Yamato ran away from home to escape his father, Kageyuki, whom he resented for not being with his dying mother in her final hours, only to get lost during a storm until a mysterious eagle Zyuman, Bud, rescued him and presented Yamato with a Champion's Proof,, which he kept as a good luck charm ever since.
Years later, Yamato discovers the Link Cube, a structure that serves as the gateway between Earth and Zyuland, and uses the Champion's Proof to travel to the latter location, where he meets four Zyumans who also possess Champion's Proofs. Upon returning to Earth and learning of the Dethgaliens' attack, their Proofs transform into the Zyuoh Changers and allow them to fight back. However, the Link Cube is destroyed during the battle and the fledgling Zyuohgers discover they need six Champion's Proofs to fix it, but the sixth Proof has gone missing. Despite this, Yamato takes in the stranded Zyumans and continues to lead them in their fight against the Dethgaliens. Later in the series, Yamato goes on to discover Bud's connection to Kageyuki and why the latter was unable to see his mother before reconciling with his father. As the red-colored "Champion of the Skies", Zyuoh Eagle, Yamato can use his Wild Release ability to grant himself a pair of wings to fly at high-speeds and wields the EagRiser sword, which can double as a chain whip and allow him to perform the Riser Spinning Slash finisher. Additionally, Yamato gained enhanced eyesight as a result of his becoming a Zyuohger and acquires additional powers and forms amidst his battles with the Dethgaliens, which are as follows: |
| Zyuoh Gorilla A form that is also known as the "Champion of the Jungle". In this form, he gains superhuman strength, the ability to produce powerful gusts from his nostrils, and perform the Gorilla Super Punch finisher with the other Zyuohgers' energies. |
| Zyuoh Whale A form achieved via the Whale Change Gun that is also known as the "Champion of Champions". In this form, he can perform the Zyuoh Final and Deep Lock finishers.
|
| During the final battle against Ginis, Yamato is empowered by the Earth's energy and gains the ability to activate a Great Wild Release similarly to his ally Misao Mondo and combine all of his forms' powers.
During the events of the film Doubutsu Sentai Zyuohger Returns: Give Me Your Life! Earth Champion Tournament, Yamato uses Cube Condor's power to fuse with Bud and transform into the violet-colored "Champion of the Blue Skies", Zyuoh Condor, gaining combined usage of both of their abilities and weapons. |
