Biography
"I will change fate with these hands!"

Born April 3rd, 1971, in Tokyo, Yamato is the son of Osamu and Kyoko Takahashi. Growing up in the suburbs, Yamato had a passion for art supported by his mother. In 1978, after being warned not to play near the main road, Yamato was struck by a bus while arguing with his best friend, Kohei Ito.

Little is known about the extensive injuries Yamato received, however his right arm and left foot had to be amputated, along with reduced mobility in his left arm. During the fifteen years after his accident, Yamato received daily physiotherapy, requiring around the clock care to carry out even basic tasks, such as dressing and cleaning. Yamato was hidden away from the world by the insistence of his father.

In 1993, on Osamu's order, Foundation X agents took Yamato to a base where he was experimented on by Elric Tachibana, converting him into a cyborg, giving him a robotic arm and leg. Waking, Yamato finds he is waiting to be brainwash into becoming an X-Rider, an AI has been installed into his cybernetics, called ARI.

Convincing ARI to help him instead of informing Tachibana that he has awoke early, Yamato frees himself again and takes the Alpha Driver, along with the Crystal FullBottle. Becoming Kamen Rider Hansei, Yamato fights against Masato, who is using a Sengoku Driver, escaping to the portal room. Yamato is attacked by another rider, named Onyx, and cast out into the multiverse.

Later, Yamato learns the truth of his origins, he is millennia-old immortal being from Mars that reverses to the state of an infant upon fatal injury. Recovering the memories of his previous incarnation, Yamato realises that his life will never be the same again.

Personality
Prior to his accident, Yamato was a cheerful and artistic child, with a short temper. However, after his injuries Yamato became bitter and angry, blaming Kohei for his accident. Additionally, Yamato grew to despise anyone who pitied or felt sorry for him, pushing away almost everyone around him, apart from his mother and his younger sister, Touka Takahashi.

After escaping Foundation X, Yamato's bitter and angry facade began to crack, as a result of ARI's presence and meeting Ryoji Hase, then later Hina Izumi. Once returning to his own world, Yamato's new outlook at life surprises those around him who remember the original timeline.
