* Super Sonic: While Super Sonic is typically blue with yellow highlights, in some media he appears with a more golden hue, like in the Sonic Adventure games. This isn't a separate form, just a stylistic variation.
* Hyper Sonic: This form, introduced in Sonic the Hedgehog 3, is a more powerful version of Super Sonic. In some depictions, Hyper Sonic has a golden aura or features, but again, this isn't a consistent, official color scheme.
* Super Shadow: This is a counterpart to Super Sonic and has a similar color scheme, except with a black body and red highlights. While not technically gold, it can be mistaken for it in some instances.
It's important to note that the color variations in these forms are often stylistic choices by the developers and artists, and not necessarily official or definitive.
