When in Rome... Sonic Underground : Season 1 Episode 18

Sonic becomes frustrated that maybe all of their efforts of fighting for freedom seem futile. Sonia suggests that they go to Oracle, the spiritual guide, to put everything into perspective. The Oracle makes a deal with the Hedgehogs, stating that if they can complete this next mission, he will reveal their future. Instead upon arrival in the ancient city, they discover their power medallions are missing and they are powerless.
