Blaze's world is a location that appears in the Sonic the Hedgehog comic series and its spin-offs published by IDW Publishing. It refers to the planet that Blaze the Cat resides on in her own dimension. It is a world that is parallel to that of Sonic's world and is home to the Sol Emeralds.
Blaze's world is the planet that is known as being the one that Blaze hails from. Not much is known about it, although it apparently has islands on it and a moon orbiting it. Other than that, the differences this world and Sonic's world are not that great; both worlds are primarily inhabited by anthropomorphic animals. This planet is also where the Sol Emeralds, which are the fiery counterparts of the Chaos Emeralds, come from.
- Blaze the Cat at some point becomes the sole reigning princess of the Sol Empire and assumes the duty as the protector of the Sol Emeralds.
- Blaze leaves the world on a quest and ends up in Sonic's world. She later returns.
- Blaze feels the will of the Sol Emeralds, which has her go to Sonic's world to prevent a "terrible event". She later returns.
- Blaze and Gardon find an amnesiac Sonic after he crash-lands on their world. After a while, Blaze manages to restore Sonic's memories with the Sol Emeralds and send him home.
