In Gradient Hue
In Gradient Hue, Green Hill Zone is a tier 1 world. In this world, Gradient explores but is soon surrounded by Egg Pawns. After defeating them, Sonic the Hedgehog shows up and brings Gradient to Station Square. Gradient is able to recruit any two of these people for this world:
After getting into Eggman's base and defeating him and his Shadow Motobug, a wormhole opens back up into the Battle Frontier, and Sonic releases a Halfcharm. Gradient decides to put this together with another Halfcharm to open more wormholes.Sonic Heroes 2, the Green Hill Zone is the central location of the map. It is the location for Sonic of Team Sonic. The Green Hill Zone has four deviants in this game.
Mecha Green Hill Zone
In Sonic Heroes 2, part of Green Hill Zone has been roboticized; this is due to the trail of destruction caused by the new (then) Dr. Kintobor as he moved out of his underground laboratory. This roboticization has never been fully fixed, but to this day offers access to the old laboratory which, in numerous storylines, contains powerups (Team Sonic's storyline contains four pairs of "Light Shoes" which enable travel across paths of rings, for example).
