Blaze is normally calm and elegant but tends to conceal her true feelings. Devoted to her position, she sometimes gets herself bogged down by her own strict discipline, which made her anti-social, shy, and unfamiliar with the concept of having friends. After spending time with Amy and Cream and meeting Sonic, Blaze has discovered the value of friendship, allowing her to accomplish tasks for the good of her people and the innocent which she could never do alone. Despite the initial boundaries separating them, Blaze now travels freely between her dimension and Sonic's to visit her friends.
