A noble soul, Blaze is normally calm, solemn and level-headed, but tends to conceal her true feelings. She is often described as elegant, which is demonstrated through her body movements and her ballerina-like fighting style. Being royalty, Blaze is quite mannerly and typically maintains a relatively quiet, stoic and formal air among others. Despite being a princess, she doesn’t liked to be called as such.

While Blaze gives the impression that she keeps her emotions in check, she is inwardly highly emotional. She possesses a fiery temper, and when she loses her composure she is quite frightening, aggressive, harsh, and prone to making bad decisions. This is due to the demon, Iblis, being sealed inside her and amplifying her powers when not in check. She also lacks in social skills and has a hard time opening up and talking to people.

In the original timeline, she acted as a Big sister to Silver the Hedgehog, sacrificing herself for him to seal Iblis away and leading to her current state. While her memories of that timeline have been wiped clean, she easily gets along with the new Silver after they meet, albeit it’s debatable that how she feels towards him has changed from sisterly to more intimate.
