Scrap Brain Zone

Final Zone is the seventh and final Zone of Sonic the Hedgehog (16-bit). It is a single Act that consists of only a boss battle, in which Dr. Robotnik tries to defeat Sonic using pistons and energy balls. No rings are available in the standard version of this Zone, although 3 are provided in Sonic Jam's Easy mode.


The arena contains four pistons, arranged as two pairs; one pair on the floor and one on the ceiling. Robotnik's attack pattern consists of causing any two of these pistons to extend and strike the opposite surface, with himself inside one of them. Sonic must hit Robotnik's piston on the side to damage the contraption. Next, the pistons retract, and generators at the top emit ball lightning that Sonic must dodge. If Sonic is able to hit Robotnik 8 times, the machine is destroyed, and Robotnik again attempts to escape in his hovercraft. This time however, Sonic can jump up and hit the hovercraft, causing it to begin exploding and lose altitude. Whether the player does this or not, he/she is taken to the ending sequence.


There are two places where the pistons could not reach: the left and right edges of the arena. You can stay in the edges to hit Robotnik and come out to avoid the balls, but the right edge is better because it's larger and because the left edge has got a low ceiling.

In Sonic Jam's easy mode, Final Zone undergoes a couple of changes that affect the difficulty of the zone. Instead of having two pistons move out, only one is moved. Sonic is also provided 3 rings before battling Robotnik.

The hit-stun period for this boss is longer than that of Robotnik's other incarnations in the game. This normally makes it impossible to hit Robotnik more than once in a single piston round. However, upon delivering the 8th hit, the destruction sequence causes the pistons to move more slowly for the remainder of the round, and if the 8th hit was delivered early enough, it is possible to get a 9th hit on the way back down. In any case, this is inadvisable, as it underflows the boss health counter from 0 to 255, thus causing the battle to continue until Sonic lands 255 more hits, which is normally impossible within the time limit.

As shown in full maps of the level, the arena and the other parts are located near the right of the end of Scrap Brain Act 2.
