I had three Ideas for Flame Sonic's Identity.
First:Eggman had Sonic's DNA and he was trying to make another Sonic to stop Sonic from always beating him,and While he left the area open(by the way, his base was near lava) and when metal sonic saw this, he knocked sonic's DNA into the lava, which made flame sonic.
Second:In the world where Blaze Lives, Blaze was 5 years old and then, Blaze's mom got pregnat and instead of another cat, it was a hedgehog.
Flame Sonic Quote:I Pesonally like this one because Blaze has Flame Powers.
Last (best):A long time ago when the world was in turmoil, Flame Sonic had been a young Hedgehog and he was the only one who could weild the chaos crystals (there are seven of them and one chaos crystal equals seven chaos emeralds) and he needed to stop the evil behind all this and while he was fighting this ultimate evil, he got knocked out and knocked into a mountian and he was in crystalized in a deep sleep by the crystals,
100's of years later Sonic was running and found him, what sonic didn't know, but Flame Sonic knew, that Flame Sonic was his ancestor but waited a long time to tell him.
Those are the three backgrounds for flame Sonic.
