For those that don't know about the game 'Shadow the Hedgehog,' I'll fill you in; Shadow the Hedgehog was a Sonic game released in 2005 for the Gamecube, Xbox, and PS2. Surprisingly, the game crashed and burned. Part of the fact came from it's ten alternate endings that you need to complete in order to unlock the final ending. Sometimes I like to think of each ending being in the official canon. However, I know that it could never be possible.

Before I continue, here are all the endings in their entirety:http://www.youtube.com/watch?v=kIHMy73vDcU

If all these endings were canon, then that would mean that Shadow destroyed the planet, continued on by ruling the galaxy, restored the planet to build the dark empire, lived on the ark after building the empire, realized how much of a jackass he was, battled with Sonic to prove he was the best once again, kicked Black Doom's ass with Sonic, and finally saved the world.

Oh, and Dr. Eggman's a time lord.
