Sonic the Hedgehog & Knuckles
After Sonic and Tails made Dr. Eggman's Death Egg crash land on Angel Island for a second time, Sonic and Tails passed through Sandopolis Zone during their mission to destroy the Death Egg for good. Knuckles later passed through Sandopolis Zone in pursuit of a fleeing Eggbot controlled by Dr. Julian Snively, Dr. Eggman's assistant, after multiple encounters on the island. During each of these trips, the heroes encountered the Guardian in the Sandopolis Zone.
- Note: From the readers point of view, this picks up from where the Sandopolis Zone's original timeline ended.
Eclipse the Darkling later passed through the Sandopolis Zone with the Dark Arms, who were carrying the Master Emerald, in an attempt to reach a shuttle in Launch Base Zone. Along the way, he encountered the Guardian as one of the traps that Rouge the Bat activated in an attempt to slow him down until Knuckles the Echidna and Shadow the Hedgehog could reach Eclipse.
