Takuya Kanbara

Takuya Kanbara (神原拓也 Kanbara Takuya) is the main character in the fictional series Digimon Frontier. Takuya, the leader of the group, chose to wield the Spirits of Fire that hold AncientGreymon's power. Takuya begins as a typical goggle boy, a member of his school's soccer club. He was at home sitting at the table just before his little brother Shinya's birthday party when he received an SMS message from a mysterious voice.

Takuya has a strong sense of justice, and tries to do the right thing. He is energetic and athletic, tending to act without thinking first. Takuya's hotheaded personality generally ends up in him arguing with Koji Minamoto but eventually they put away their differences and become friends. Takuya acts like an older brother to Tommy Himi (Tomoki Himi), who reminds him of Shinya. He was voiced by Junko Takeuchi (Japan), Michael Reisz (US, TV) and Dave Wittenberg (US, movie and EmperorGreymon).
