The Scrap Brain Zone is Robotnik's first and one of the most iconic fortress.

Acres of industrial superstructure. Ground encased in soulless concrete and steel. A thousand automated factories, belching jet-black pollution into the rancid air as robotic horrors crawl across the metal gangways.

Sonic the Hedgehog (16-bit)


Scrap Brain Zone Act 3

Scrap Brain Zone in the original Sonic the Hedgehog (16-bit) is the sixth of seven levels. It is a trap-filled industrial stage with many dangerous machines such as saws, flame vents, plus disappearing and rotating platforms.

At the end of Act 2, Robotnik appears behind a force field and pushes a button which sends Sonic into Act 3 (the only level-ending sequence in the game). This is a level similar to Labyrinth Zone (although the colors are changed), and unlike all the other Act 3s, has no encounter with Dr. Robotnik at the end. Instead, Sonic springs directly to the Final Zone.

This difficult third act is essentially a harder rendition of the Labyrinth Zone, mainly because air bubbles are few and far between, forcing Sonic to cover long distances on one breath, racing to the next bubble before drowning. Most of this however, can in fact be bypassed completely. When Sonic pushes the button at the beginning, causing the floor to move downwards, he can fall in front of it and down the slope. From then on, if he avoids falling down the pits, he will soon find himself at the end of the level. Taking this route, the act can be completed in about 35 seconds with the minimum of danger to Sonic's life count.


Aside from Ballhog, all of the Badniks from this Zone first appeared in previous Zones.

Ballhog Tonton (トントン) Tonton

Burrobot Mogurin (モグリン) Mogurin
Caterkiller Nal (ナール Nāru) Nal

Sonic the Hedgehog (8-bit)


Scrap Brain Zone also appears in the Game Gear / Master System version of Sonic 1, as the fifth stage. Unlike the other stages in the game, Scrap Brain has three standard Acts, and lacks a boss. Scrap Brain Zone Acts 2 & 3 are very maze-like, and Sonic may find himself doubling back to re-activate switches or take a different route through a teleporter platform.


In lieu of a boss fight, the end of Scrap Brain Act 3 shows Sonic chase Eggman onto a floating platform, which the Doctor uses to flee to his airship hidden within Scrap Brain's industrial smog. After helplessly watching his nemesis escape, Sonic is no doubt relieved to discover the platform comes back down, allowing the hedgehog to continue on to Sky Base Zone.

The 6 racetracks in Sonic Drift are sited within the first 6 zones of Sonic the Hedgehog; accordingly, Scrap Brain Zone features as one of the courses.

Sonic Drift 2: Iron Ruin?

Main article: Iron Ruin

The future of Robotnik's massive bases after Sonic has defeated the Doctor (this time) is rarely discussed in the games; however, for Scrap Brain Zone, hints as to the South Island base's fate may lie within Sonic Drift 2. The background for the Iron Ruin racetrack bears striking resemblance to the immense industrial zone, though (as the name suggests) the giant manufactures lie corroded and destroyed.

SEGA Superstars Tennis


Scrap Brain in Superstar Mode of SEGA Superstars Tennis.

Scrap Brain Zone is an unlockable court in SEGA Superstars Tennis. It appears a bit gloomier than the 16-bit version. On the side of the court is the machine Robotnik used as the final boss from Final Zone, still moving up and down. Spectating from the sideline is Metal Sonic and the Egg Gunners from Sonic the Hedgehog (2006). This is also the location of many of the missions in Superstar mode. In these missions Egg Gunners fire at you while you collect rings and avoid bombs that resemble Bomb from Knuckles' Chaotix. There are a number of unlockable tracks for this court from different Sonic games: Music from Final Fortress, Bullet Station, Egg Fleet, and Scrap Brain Zone are available.

Super Smash Bros. Brawl

The Genesis version of the Scrap Brain Zone music is an unlockable prize in Super Smash Bros. Brawl. It can only be used in Green Hill Zone or Custom Stages.
