I didn't mean they are the same person in the game's story.

I meant in 'real-life'. What I mean to say is that SEGA had a concept of a princess with a fire curse and all. That concept was initially given to Blaze in 2005. They wanted to continue the story in Sonic 06 but because of some drastic changes (probably the writing team got fired?) they gave that concept to another character.

They still wanted Blaze in the game (or they just wanted Silver to have a companion). But because Elise's concept is based on Blaze's, they changed Blaze's backstory for one game only.
