Conceptually, these characters are the same. And the dates of their debuts are also around the same time.
This theory says that Blaze and Elise are based on one concept, making them the same person. But then the development team divided it into two people, with one of them just being a one-time character (Elise).
Further proof of them being the same person is in Sonic 06. Blaze was pushed into an entirely difference role in Sonic 06 with no explanations at all and that version was Blaze was never used again. Could it be because she was too similar to Elise?
- Blaze isn't a princess in the game
- No mention of fire curse
- No interaction with Sonic
- No Sol Emeralds
Basically, they removed whatever made Blaze similar to Elise, just for one game only.
