Metal Overlord, Metal Sonic after having absorbed the energy of Chaos, Shadow and some other people.
Although personally, That last answer did give me the giggles.
get the 7 chaos emeralds
No you cannot. The emeralds are only usable during the Final story against the Final Boss.
You have to have completed heroes story and then at the very end of the babylon's story,is the final boss,which is a ghost guardian.
I assume you're talking about Sonic Heroes. The answer is nope, you can only play as Super Sonic in the final boss fight against Metal Overlord *Metal Sonic*.
Yes, For The Last Secret Boss.
He does for the final boss, but that's it
You cant.Only in the final boss you can
at the end of subspace sonic will appear on the final boss kill the final boss to unlock sonic
The Final boss is called "The Seven Heroes" The boss is actually the seven main villains of the game, the Seven Heroes, combined into one.
You can only play as super Sonic once you unlock the final story(complete all stories and collect the seven emeralds). After the first three phases of the final boss, you will play as super Sonic, super Tails, and super Knuckles. There is no super Shadow.
You can be super sonic on the final boss boss for ps3, ps2,wii, and xbox 360
i don't think there's a final boss mode in sonic adventure dx
