Avalon is an area that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. It is a territory located on Sonic's World and contains the Eurish Egg Army of the Egg Army and their base.
When Doctor Eggman, Orbot, and Cubot went to Avalon in Eggman's Egg Mobile-bi-plane after crash-landing in Efrika, the G.U.N. forces were already stationed there, causing trouble for the local Egg Army unit. After being shot down by G.U.N. pilots, Eggman and his lackeys crashed-landed at Avalon's Egg Army Base.
With some supplies courtesy of Lord Mordred Hood, Eggman turned his Egg Mobile into a combat vehicle and ambushed the G.U.N. Carrier. Eggman then set his Egg Mobile to attack the control station of the carrier, thus destroying the whole thing, while he, Orbot, and Cubot escaped in a stolen jet.
- Avalon is named after the island that appears in the Arthurian Legend.
- With the name Avalon being from a medieval-culture location, Avalon location in Eurish, which is based real-life Europe, is befitting.
