Calm, soft-spoken, and reserved, Yazoo has few facial expressions and rarely shows strong emotions. Yazoo's more playful side shows when bantering with his brothers, particularly when light-heartedly teasing Loz, or maliciously taunting the Turks. Yazoo is somewhat more expressive and sadistic when fighting, often coldly smirking and quietly laughing. He displays crazed excitement during his takedown of the Turks' helicopter before recomposing himself, which hints at a shade of instability.
