Green Hill Zone
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. Brawl, Super Smash Bros. for Nintendo 3DS and Super Smash Bros. Ultimate. It is unlocked after Sonic himself is unlocked. In Brawl and Ultimate, Sonic is fought here for his unlocking battle.
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. The ground of the middle part is susceptible to attacks, and chunks of it crumble away if they sustain enough damage, transforming the center of the stage into a pit. The broken parts regenerate over time: players below it when this happens will fall through it.
Occasionally, checkpoint lampposts randomly spring up. 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. They only deal 10% damage, but cause decent knockback with KO capabilities. After a few seconds, spinning lampposts stop and can be attacked again. They disappear on their own after a while.
Ω forms and Battlefield form
In Super Smash Bros. Ultimate, the main platform of the Ω form and Battlefield form is similar to the Ω form in SSB4; however, it does not extend below the blast line and is resized and reshaped to match Final Destination and Battlefield, respectively. The three soft platforms of the Battlefield form are reminiscent of the grassy checkered soil of the ground and are unique to this form.
This stage originates from the eponymous level in the first Sonic the Hedgehog game; it later appeared as an Easter egg in Sonic Adventure 2, its first 3D appearance, and as the opening stage of Sonic Generations. It is depicted as a lush paradise, with many plants and a peculiar checkered ground design. Some parts of the ground, often located at the edge of cliffs, crumble when stepped on.
Shuttle loops, which have to be ran through by building up enough speed, first appeared in Green Hill Zone, and became a prominent feature in later Sonic games.
Item Boxes are another recurring element in Sonic games: they display a picture depicting the item they contain. If the image is Sonic's head, they grant the player an extra life.
Throughout Sonic the Hedgehog, lampposts act as checkpoints and are activated when Sonic runs past them. Upon activation, the blue orb on their top turns red and makes the orb spin for a short time.
The characters which appear in the loop are: Miles "Tails" Prower, Sonic's friend who first appeared in Sonic the Hedgehog 2; Knuckles the Echidna, Sonic's rival who made his debut in Sonic the Hedgehog 3; and Silver the Hedgehog, who debuted in Sonic the Hedgehog (2006).
Super Smash Bros. Brawl
On March 17th 2009, the BBR announced that the stage should be banned, as opposed to its former status as a counterpick, and the stage has since been universally banned in tournament play. Many players take issue with Green Hill Zone for its extremely campy nature: the most effective strategy when fighting here is to camp the signposts, which have a centralising effect due to their significant defensive power for an already highly defensive game, can severely elongate the flow of the match. Another major issue with the stage is its deep slope design, which, besides being awkward to fight on, can create a cave of life effect since players can DI and tech into the ground. Furthermore, both sides of the stage have permanent walk-off edges, favoring chain throws or simply camping the edge; the frequent absence of a lower blast-line also negates any off-stage play.
