Kazuya is driven by his need for control, power, and revenge against his father. After initially appearing to be a sympathetic protagonist in Tekken, from Tekken 2 onwards he has shown that everything comes second to his plans for complete control and power. Kazuya is violent and vengeful due to trauma, corrupted by his thirst for power, but ultimately capable of love. Kazuya is generally presented as a proud, yet bitter, vindictive, stubborn, smug, cynical, manipulative, and cold-blooded man.
