In games like Sonic Adventure, Sonic Adventure 2 and the Sonic Rush series however, Sonic's middle quills would retain their normal shape, making his overall quill style look identical to Shadow's. Up until Sonic Adventure, his middle head quills would also get longer when transformed.

Prior to Sonic Adventure, Sonic's eyes remained black when transformed (except in Sonic the Hedgehog 3, Sonic & Knuckles, and Sonic the Hedgehog 3 & Knuckles where they would turn turquoise), his golden aura was absent, and his quills would sometimes be more upturned and messy. Over the course of the Sonic series, Super Sonic's appearance has changed gradually.

His aura also sometimes displays either faint sparkles or electrical sparks. He also possesses a golden aura that varies in size and can be anything from smooth to flame-like in shape. Additionally, his green eyes become ruby red and his facial expression becomes more aggressive, with his eyes gaining sharpened corners. When transformed into Super Sonic, Sonic's blue fur becomes golden yellow in color, his peach skin gains a slightly golden hue, and the quills on his head become upturned.
