Blaze's dimension is a location that appears in the Sonic the Hedgehog comic series and its spin-offs published by IDW Publishing. It is the dimension which Blaze is from, and is home to the planet from which she hails. It exists in parallel to Sonic's dimension.
In spite of being different dimensions, the differences between this reality and Sonic's are not that great; both dimensions so far are shown to be inhabited by anthropomorphic animals. This dimension is also where the Sol Emeralds, which are the fiery counterparts of the Chaos Emeralds, come from.
