Mobius-Seventeen

Mobius-Seventeen is an alternate zone where Sonic is a super hero called Stealth the Hedgehog and Robotnik is a super villain called Professor Egg.

History
One day when Stealth was having one of his many battles with Professor Egg, they notice a giant hand over them as it crushes their zone. The one responsible for destroying their zone turned out to be Mammoth Mogul, who was destroying nearly every other zone except for Mobius Prime. When Titan Tails defeats Mogul, he restores all the destroyed zones, including this one.(StH: #149, #150)
