Aman-Rapi looks nearly identical to Sonic, except that his quills are shaped in a different style, his arms are blue, and he wears ancient Egyptian clothing.
In his own time, Aman-Rapi foretold the coming of Doctor Robotnik, and inscribed a blueprint on how to defeat him on a scroll which was placed in his tomb. Later, when Sonic and the others came looking for the scroll, Aman-Rapi's mummified minions mistook Sonic for him. After the Sonic Underground granted his request for a song, he used his spell of immobility to freeze the invading enemies long enough for them to escape. Unfortunately, the scroll was so old that when it was removed from its tube, it crumbled to dust. However, Aman-Rapi had left one message: inscribed on the tube was a hieroglyph, which when translated, meant "Hedgehogs will prevail".
- Two Ancient Egyptian ancestors of Sonic, Masonic and the Mummified Hedgehog, previously appeared in the Adventures of Sonic the Hedgehog episode "Robotnik's Pyramid Scheme".
- Aman-Rapi's voice sounds exactly like Sonic's, mainly because the character is also voiced by Jaleel White.
