The princess of Blaze's world, entrusted with the mission of wielding and protecting the Sol Emeralds. She usually maintains a calm and dignified appearance. However, this seems to be because she tries to suppress her inner passion with reason. While faithful to her mission as the guardian of the Sol Emeralds, she has a tendency to bind herself too strictly. Perhaps because of this, she is very shy when around others. However, after meeting Sonic and his friends, Blaze's perspective seems to have changed slightly. She can travel between her world and Sonic's using the power of the Sol Emeralds, though it seems she occasionally leaps through time and space in the process.
