Character: super shadow
Super Shadow (スーパーシャドウ Sūpā Shadō) is a transformation that appears in the Sonic the Hedgehog series. It is the Super State of Shadow the Hedgehog, achieved when he harnesses the power of the seven Chaos Emeralds.
When transformed into Super Shadow, Shadow's black fur turns into a golden lemon-cream color and his eye color becomes completely ruby red. Other than that, his additional fur colors, and quill style remains unchanged. He also possesses a golden aura that varies in size, which can be anything from smooth to flame-like in shape. In Shadow the Hedgehog however, his quills pointed upwards like Super Sonic's instead of being in their normal stance.
In this form, Shadow truly lives up to his title as "The Ultimate Lifeform". His numerous and versatile Chaos Powers become greatly enhanced beyond their normal limitations, granting him unstoppable destructive power and absolute control over time and space. In addition to the power of flight, increased speed, and invulnerability. Super Shadow is widely considered to be one of the most powerful characters in the entire series.
Like Super Sonic, this form is heavily dependent on Ring Energy and the Chaos Emeralds. Separation from these will leave him vulnerable.
