Episode Title:
The Devil Is in the Tails
Episode Description:
With Grim Big destroyed, the team moves in on Nine's fortress. However, Nine destroys the Mothership, forcing Mr. Dr. Eggman to escape, with Dr. Done-It's ship also shot down. Nine forms more Grimions and Sonic's allies are overwhelmed. Angered, Sonic calls up his comrades and forms up a plan to beat Nine. He intercepts and battles Nine, who uses more energy to overpower him. As he falls off the fortress, Sonic uncovers a new ability in his Grim shoes: creating hexagonal footholds and shields to protect himself from Nine's attacks. Having survived their apparent demise, Sails and Mangey take control of Grim Big's remains to help turn the tide of the battle...
