Super Silver

From Sonic Retro

Super Silver is Silver's Super State. Like Tails and Knuckles in Sonic Heroes, he did not transform on his own, but was given the power to transform by Super Sonic. He appears during the final battle of the 2006 Sonic the Hedgehog game.

Super Silver is a white-gold color and has a bright yellow mane. His hair continuously floats and he has red eyes. In addition to the usual speed, flight, and defense increases of a Super State, Super Silver gains a new ability called the "Shield of Light". He surrounds himself with a circular force field, and any objects that enter this field fall under his control. He is also able to use the same charged dashes as Super Sonic.

As the events of Sonic the Hedgehog were erased from the series's storyline, Silver technically never transformed at all.
