Exo-Raikou
It's over. I'm sorry, but it's over.
But remember that everything that happened in Sonic 06 was erased from history at the end of the game, so essentially that one irregularity is rendered null and void. Giving the Chaos Emerald to Elise, however, was part of a far greater paradox. Now, I haven't played this game (for better or worse) but I believe the issue goes something like this:
This cycle is infinite, so there is no way for the emerald to actually enter the story - it was simply always there.
- Silver goes back in time and gives the emerald to Elise.
- Back in the present, Elise gives the emerald to Sonic (or he acquires it indirectly somehow).
- Sonic gives the emerald to Silver so that he can use Chaos Control to go back in time.
- Repeat.
...I really wish I could come up with something more than this. D:
True, true. But as far as that game's events go, Elise having the Chaos Emerald means that it could not have been used in that game's "continuity." In said continuity, the Emeralds were never united and thus all the Super forms couldn't have been utilized.
I'm probably reading too much into this.
