Egypt is a transcontinental country on Planet Earth. Its ancient history is a popular setting and theme in fiction, exploring its kings, pyramids, deserts and other elements of the country's culture.
History
Following Doctor Robotnik's attempt to crash Shanazar into Mobius, the combined planet now contained gateways to a variety of New Zones. To make Mobius even more of a portal to other destinations, people could now use the Ring of Eternity to visit Earth at any time, any destination. Tekno the Canary improved this functionality further by hooking her own computers to the Ring. This enabled the Freedom Fighters to choose when and where they wanted to visit Earth.
Sonic the Hedgehog was called in to witness the first use of this technology, with both he and Amy Rose witnessing an Egyptian slavemaster bullying a worker for tripping over. The hedgehogs immediately entered the Ring and tackled the official. Their arrival invited the interference of Set, Hathor and Thoth, three supposed "Gods" that ruled over ancient Egypt. Set wielded the Staff of Power to demand respect, but this earned him the other deities' ire. Discovering that they were really exiled aliens, Sonic intervened and grabbed the staff before defeating Set in battle. The slaves realises their masters' frailty and became free. However, Set would not accept this defeat and killed his fellows before following Sonic and Amy back to the Emerald Hill Zone. Tekno reversed the Ring's power to suck Set back through, but ended up in the limbo dimension instead.
In Sonic the Comic Online, the region of Solstice and the surrounding areas resembled Egypt. Set's Pyramid of Atum was built to look like the pyramids he used to have built on Earth.
