Okay, I'm sorry, but I got a little impatient of waiting for someone to guess it right, so please forgive me.
It is actually a fact.
Here's the lowdown of the whole final battle. Sonic and Shadow (a black hedgehog that is Sonic's rival.) had transformed into their super forms to face the evil Dark Oak's ultimate form. He had transformed into a black dwarf star. What was different about this black dwarf star was that it was about to implode with a force so powerful, it would destroy the whole universe.

What was worse, he had created a forcefeild that stops all animal based life forms from attacking him. :blink: Despite this, both Sonic and Shadow tried to attack Dark Oak, but upon touching the forcefeild, they were paralyzed.
That's when Cosmo, a plant based life form that looks more human than plant on the outside, activated her ultimate power. A power she could only use once. With her amazing power, she cut right through the forcefield and attached herself to Dark Oak, immobilizing him and deactivating his forcefield and freeing Sonic and Shadow.

Now, it would still require a very powerful attack to finish Dark Oak for good. However, Cosmo knew that once Dark Oak was destroyed, she would be gone too. Yet, she was willing to give her life to save everyone from the evil.
She then told the one she loved, Miles "Tails" Prower, to use the Power Cannon on Dark Oak. Tails couldn't do it, for he knew that the blast would destroy Cosmo as well, and he loved her too much to do that to her.
Cosmo explained to him how it was the only way to defeat Dark Oak. After that, there was a very tearful goodbye between the two lovers. Sonic and Shadow entered the Power Cannon while still in their super forms to ensure the blast would finish Dark Oak, for it required someone who could use the Chaos Emeralds, which is what gave them their power.
Then, with one last goodbye, Tails pushed the red button that would activate the Power Cannon, launching the final attack, thus finishing both Dark Oak, and sadly, Cosmo as well.

Sonic searched in vain for anything left of her. Hoping for a miracle of some sort that she was still alive. Yet, all that remained of poor Cosmo was a small white seed, which he gave to Tails, knowing how much he loved her. :cry2
Here is a picture of the one who sacrificed herself to save the universe.

And here is the love of her life, who had to kill her to save the universe.

And yet, it still qualified for Y7. (7 and older for those who don't know.)
Also, after all this, there are those who belive Cosmo will return. Most likely from the seed. I do see that as a possiblity. After all, she is a plant.

Well, with that explained, it is now a free for all. The turn goes to whoever can come up with a Fact or Crap! statement first. :^.^:
