The Sol Zone is the home universe of Blaze the Cat, Marine the Raccoon, and the Coconut Crew. It is an alternate Zone with unknown connections to the Prime Zone, and particularly with the planet Mobius.
Unlike Mobius Prime, Blaze's World in the Sol Zone produced Sol Emeralds instead of Chaos Emeralds, and an artifact known as the Jeweled Scepter-originally hidden deep beneath the planet's surface-as opposed to the Master Emerald. It also gave rise to various mineral substances referred to collectively as "material", useful for the construction of vehicles. This zone was first encountered by Sonic the Hedgehog and Miles "Tails" Prower when their plane crashed and they mysteriously arrived on Seagull Beach of Southern Island. Marine had gotten possession of the green Chaos Emerald, though it was stolen shortly afterwards by Johnny. Following this, Sonic, Tails, Marine and Blaze fought against Johnny, Captain Whiskers and Dr. Nega, defeating them and retrieving the Chaos Emerald. (StH: #180, SU: #1, CSE)
Shadow the Hedgehog accidentally ended up in the Sol Zone after using Chaos Control to teleport himself and Metal Sonic away from the battle taking place in Moebius. Shadow was rescued by Marine and Blaze and brought on board the former's ship, the Ocean Tornado. Following this, the three fought against Metal Sonic and destroyed him, and Shadow was given the green Chaos Emerald to help him return back to Mobius Prime. Unfortunately, the zone was imperilled by the scattering of the Sol Emeralds across the multiverse, leaving the planet suffering from terrible natural disasters. This forced Blaze to leave her home-world temporarily unguarded while she set out to find the magical gemstones. (SU: #1, #21, #22, #23, #24)
While the Zone was not directly affected by the second Genesis Wave, that didn't stop Blaze from being dragged into the chaos that ensued across the Prime Zone and another zone. A normal day for Blaze and Marine was interrupted by a flash of white light, which would lead into Blaze becoming Blaze Woman, one of Dr. Eggman and Dr. Wily's Roboticized Masters.

The most important location in the Sol Zone is the planet that is home to Blaze the Cat and the Sol Emeralds. The vast majority of the planet is made up of ocean, with countless islands of varying size found across it. While some of the large islands are home to modern civilizations, many of the smaller landmasses remain untouched.
