Aiba, Takaya

相羽タカヤ

Takaya Aiba is the elder of the twins (by 30 minutes). His father saved him before he transformed into a Radam Tekkaman, and he escaped to defend Earth from their invasion. Aki and Noal found him when he fell to Earth; since he claimed to have lost his memories, they called him D-Boy. He can only remain in Tekkaman form for 30 minutes before losing control and becoming a killing machine. He knows he must fight his siblings and close friends, but he still decides to continue, even though it pains him. He does not care what happens to him in order to save the planet.
In the English version, he is called: Nick Carter.
