Neutral Zone

The Neutral Zone is an alternate dimension that can be reached through the Cosmic Interstate.

History
After Robotnik Prime sees Robo-Robotnik as a threat and teams up with the many Sonics whom Sonic Prime has gathered, he explains to his new "allies" that Robo-Robotnik is keeping an alien weapon called the "Giant's Hand" in the Neutral Zone. A squadron of Sonics head to the Neutral Zone with the intention of retrieving the Giant's Hand, but discover that the Neutral Zone is nothing but a colorless void. The Sonics find the Giant's Hand, but Evil Sonic and an army of Shadow Swatbots. After a brief battle, the Swatbots are defeated, but Robo-Robotnik locates the Giant's Hand and teleports it back into his base. (StH: #19)
