Tails takes a failure during a battle with Eggman to heart. He feels that even though he's the smart one in the group, he's just not smart enough to help Sonic and the gang. So he creates a machine to duplicate himself and form a "brain trust." But will he and his duplicates be smart enough to defeat anything that Eggman can come up with?

Steve Eggman comes to town, claiming to be Eggman's long lost brother. He wants to fight for good alongside Sonic and the gang.

Morpho sends Sonic to a dimension where he never existed. Sonic must unite his gang and help take back the alternate dimension village.
