The Sun Valley Zone is a location that appears in the Sonic the Comic series published by Fleetway Editions. It is a Zone of Mobius, renowned for being perpetually sunny. It contains tall, rocky mountains and dry scrubland.
Windy Wallis and Agent X once used the Sun Valley Zone to lay a trap for Miles "Tails" Prower. Windy Wallis used her weather machine to wreathe the Zone in thick fog, and Agent X (disguised as Johnny Lightfoot) lured Tails to the Zone in order to investigate. However, Tails managed to defeat the villains and destroy the machine, restoring the Zone's natural weather.
