Super Shadow destroyed Black/Devil Doom completely, ending his existence. However, you could kinda say he lived on inside Black Death in Sonic Universe: Shadow Fall, but Shadow destroys him too. Metal Sonic never really died, the Metal Sonic in White Space is CLASSIC Metal Sonic. Modern Metal Sonic is still alive. Dark Gaia mostly likely did survive, but he was put back to sleep for another hundred/thousand years. The decaying/blood gushing were just from severe wounds from Super Sonic. Getting hit in like 7 or more eyes can do that to you, lol.
