Never Forget

What if Maria and Sonic had swapped places...well to the sense that Shadow became the Hero of the both Past and Present.

Shadow is rarely seen on Mobius, being G.U.N's secret Bio Weapon, they have tabs on him at all times, but he was never late whenever there was a threat to the planet. But what the dark hedgehog did on his own time...

Well he was at the Colony where he was created, he was just drawn to the place, for reasons that didn't share.
