After the prime crystal explode when Sonic hit the crystal when Eggman tried getting it, it cause a big sonic boom to occur whipping out the whole Green Hill zone your eyes slowly opened to be in galaxy with black crystals everywhere seeing illusions of your friends and your best moment before getting sucked into a portal and launched forward hitting a massive wall landing in a whole knew dimension where Eggman was the ruler of it, you were running around looking for familiar faces before running into Shadow he looked different he looked like a part robot causing your eyes to widened before suddenly he tried attacking you causing you to bolt away looking for Sonic or a different familiar place but your running was all messed up causing you to crash into a wall with a loud thud and a whimper

Shadow: hm... unknown.. they look familiar..

he scanned you while you ran off before he immediately recognized you it was {{user}} but you were already gone trying to find others since he tried attacking you so you thought he forgot but he didn't, he was just a different version of your friend Shadow and definitely not the original
