Super Shadow

Super Shadow (スーパーシャドー, Super Shadow) is the name of the form Shadow takes when undergoing a Chaos Metamorphosis and achieving a Super State. Similar to Sonic, this has became Shadow's most common form to power up to.

Overview
By absorbing or using the energy of the 7 Chaos Emeralds, Shadow is able to achieve his super state. As shown with other characters, there might be other ways for Shadow to achieve this state, but they haven't yet been shown. Shadow takes a drastically different appearance compared to Sonic, with his quills not changing much other than being slightly spiked upwards more, and his fur becoming a creamy yellow color. The red of his body tends to also become more of a scarlet color, and a yellow aura surrounds him. During his first appearance, Super Shadow was more of a silver color.

Shadow gains the general abilities given by a Super State, however, he tends to have drastically different effects while in this form. His Limiters tend to be set to overdrive, without much damage to himself, however, this causes his stamina to drop drastically. Many of his usual techniques tend to be stronger, or have better variations of themselves, such as his Chaos Spears being much larger, or his Chaos Blast being able to wipe out an entire city.

A major weakness, as stated before, is the increased amount of Stamina Shadow uses up when in this form. if he's not careful, he can completely burn himself out, more than the other characters do, and as seen in Sonic Adventure 2, he injured himself to the point he was on the brink of death.
