Located on South Island, it is an area consisting of distinctively checkered ground with a grass surface and a lush biome, including palm trees and multiple flower species. Green Hill Zone debuted as the starting stage in Sonic the Hedgehog. Green Hill Zone, as it originally appeared in Sonic the Hedgehog. Occasionally, Tails, Knuckles, and Silver run along it. The background features a giant shuttle loop with a 1-Up monitor above it. They disappear on their own after a while. After a few seconds, spinning lampposts stop and can be attacked again. They only deal 10% /8% damage, but cause decent knockback with KO capabilities. They are normally blue, but when attacked they turn red and start spinning: in this state they are able to hurt players other than the original attacker. Occasionally, checkpoint lampposts randomly spring up. The broken parts regenerate after 20 seconds. The sections will naturally break after a random amount of time between 90-150 seconds, regardless of how much damage it has taken. The ground of the middle part is split into three sections that are susceptible to attacks, and the sections will crumble away if they sustain enough damage (125 /100 damage), transforming the center of the stage into a pit. The stage consists in a single piece of land with a bridge on its left, walk-offs at both sides and a depression in the middle. In Brawl and Ultimate, Sonic is fought here for his unlocking battle.

It is unlocked after Sonic himself is unlocked in Brawl but is available from the start in subsequent games. Green Hill Zone ( グリーンヒルゾーン, Green Hill Zone) is the stage that represents Sonic the Hedgehog in Super Smash Bros. The ground can collapse after attacking it, so be careful! A Point Marker will twirl when the ball is hit, dealing damage to anyone nearby.

The concave landscape and blue Point Marker are iconic to this stage.
