Synopsis
Sonic, Ted, and Paco race over to the location of the wormhole, which they discover to be right under a statue of the Mayor. As they investigate, Sonic warns the team that this could be something very dangerous and that they need to be ready for anything. As Sonic moves forward to investigate, he is sucked into the wormhole. Inside, he finds the man in the suit fighting a Cosmic Entity. Sonic asks the man in the suit what's going on and the man replies by telling Sonic that this Entity is what Frieza was telling them about. Sonic tries to join the fight, but the man in the suit warns him that it's too dangerous for him and he should leave it up to the Masters of Magic. However, the Entity, noticing Sonic, freezes him in place. The Entity tells Sonic that the people of the Land of Ooo trust him to keep them safe, but then asks what if they didn't. The Entity then enters Sonic's body and sends both himself and the man in the suit out of the wormhole. Ted and Paco stand over an unconscious Sonic waiting for him to wake up. As he does, he tells them they need to move the shard to safety.

Sonic assembles the rest of the team and they make their way to Pig King's Castle. Pink Panther asks Sonic why they are relocating the shard here and Sonic replies with "just because." Oscar comments that their leader is acting very strangely. Sonic then tells TFAWPS that now that they've helped him get the shard here, it's time for them to get lost and begins attacking them. Sonic says that he's going to use the shard, to take over the Land of Ooo and the Dark Order. Sonic then attacks Mofo and Buster, knocking them down. Sonic approaches them and the Entity extends himself to take control of them as well. Paco then suggests that they attack, but Pink Panther tells him that they can't attack their friends. Ted suggests a retreat, with Phoebe agreeing with him. As TFAWPS retreats, Sonic, Mofo, and Buster enter the castle and attack Pig King and Master Robot, kicking them out.

Back at TFAWPS Tower, Pink Panther sits down with Ted, Paco, Oscar, and Phoebe to try and figure out what's going on with Sonic. Phoebe says that she believes there is a dark energy living within him. Pink Panther suggests returning to the lab and doing another investigation. Upon returning to the castle, they find that it has been completely redone. Suddenly, Pink Panther is shot in the back with a laser fired by Zack, Bart, and Agent Yellow. Ted, Oscar, and Phoebe turn around, only to also be shot. Zack comments that he loves what Pig King has done with the place and enters a fight with TFAWPS. Paco battles Bart while Pink Panther takes on Zack. Pink Panther tells Zack to beat it because they're dealing with something here and don't need any added interference. Zack says that he's here for the shard, which makes it his business. Suddenly, Sonic, Mofo, and Buster emerge from the castle telling taunting them, saying they've brought new recruits for their evil empire. As everyone avoids Sonic, Mofo, and Buster's attacks, Oscar quips to Zack that maybe they could schedule a battle later in the week, which Zack replies would be lovely. Sonic says that he's raided Lupina's Lab and got a whole bunch of new experimental technology and is itching to try it out. Teaming up with the Dark Order, TFAWPS battles the robots. With everyone distracted, Sonic sends Buster and Mofo out to get new recruits, hypnotizing Bart. Sonic then laughs evilly.

Sonic then taunts his former teammates and enemies and tells them to join his conquest of the Land of Ooo. Ted says that he will never and charges up his energy, but his attack is thwarted by Sonic, who knocks him out of the sky. Ted falls unconscious and is picked up by Paco, who says he'll get revenge, but is talked down by Phoebe, telling him they need to get Ted to safety. Zack orders a retreat for himself and Agent Yellow and tells TFAWPS to run if they value their lives. Pink Panther reluctantly agrees with Zack and pulls TFAWPS out of there.

Paco and Phoebe nurse Ted back to health in TFAWPS Tower, but Ted is put on bed rest. With half their members unable to fight, Oscar and Pink Panther decide to recruit some help. Lupina says she'll stay behind and keep an eye on Ted while Pink Panther, Paco, Oscar, and Phoebe travel to the Sanctum to speak with the man in the suit. As the team enters, they find the man in the suit and the man in the silver suit waiting inside. Oscar and Phoebe restrain the man in the silver suit and Paco restrains the man in the suit. Pink Panther then questions them asking who they are and why chaos follows every time they show up. Pink Panther tells him that they've lost three friends and one on bed rest because of whatever happened at the wormhole and the man in the suit confesses. He introduces himself as Reeces and the man in the silver suit as Hershey, members of the Masters of Magic. He tells them that they've been tracking a Cosmic Entity and his heralds and informs them that they have their eye on the Land of Ooo.

After some more discussion, Reeces reveals that he has a plan to save Sonic and the others. He says that if he can get close enough to the Sonic, he can pull the Cosmic Entity out and send him back to the Negative Zone. He explains that the more bodies he takes over, the easier it will be to pull him out. Reeces says that he's recruited some more help to their cause and introduces Wave. Wave says that she heard about what happened to Ted and reminisces about the times she, Ted, Vector, Charmy, and Espio had back on Fin-Land and agrees to help get her friend back. Suddenly, the Sanctum doorbell rings. Hershey answers it and the group finds Pig King and Master Robot at the door. TFAWPS immediately gets into attack position, but Pig King says that he's here to help stop Sonic and regain his castle. Pink Panther tells Pig King that he's lucky they're desperate and invite them inside while Reeces goes over the plan.

At the castle, Sonic explains to Mofo, Buster, and Bart about his plan to use the shards to take over the Land of Ooo, and Bart informs Sonic that Zack has a shard at his Lair.

Sonic, Mofo, Buster, and Bart storm Zack's Lair, but Zack and Agent Yellow are unable to hold them off. Suddenly, Master Robot runs up carrying Pink Panther, Oscar, Phoebe, Paco, Reeces, Wave, and Pig King. He drops them off and the new team begins fighting. Reeces says that, as odd as it may sound, they need to defend Zack and his shard to make sure that Sonic doesn't get his hands on it. Oscar and Phoebe battle Bart, while Reeces and Wave take on Sonic, but Sonic quickly overpowers them. Reeces tells Wave to hold him off a bit longer and Reeces conjures a spell, knocking Sonic out, briefly. Taking this opportunity, Pink Panther and Reeces approach Zack and Agent Yellow and ask him to put aside their differences and help stop Sonic. Zack asks what's in it for him, and Pink Panther reluctantly agrees to let him keep the shard, for now. Pig King points out that Sonic and his evil allies have escaped back to his castle. Paco asks if this new group has a name and suggests they call themselves the Defenders.

As the Defenders arrive at Pig King's Castle, Sonic taunts them yet again and they enter a giant battle. Agent Yellow battles Bart, Wave and Pink Panther battle Mofo, Master Robot, Oscar and Phoebe take on Buster, while Reeces, Zack, and Pig King take on Sonic. As Zack and Pig King battle Sonic head on, they restrain him long enough for Reeces to open the portal under Sonic's feet. Reeces grabs Sonic and the two of them enter the wormhole. As they fight, Reeces performs the spell, and the Entity leaves Sonic's head. Meanwhile, Mofo, Buster, and Bart snap out of it. Zack orders Agent Yellow and Bart away, saying that their work is done here. Pig King and Master Robot then retake their castle, kicking a confused Mofo and Buster out of the way. Reeces and the Entity battle over Sonic's unconscious body, with Reeces performing a highly complex and dangerous spell to cast the Entity away. Sonic's soul is the returned to his body and he and Reeces leave the wormhole.

Back on the Land of Ooo, Sonic greets his teammates and their allies that rescued him. The group returns to TFAWPS Tower where Sonic thanks them for organizing the Defenders but then orders that the Defenders disband so they can return to their TFAWPS duties. Ted greets Sonic and tells him that he isn't mad at him for hurting him and the two make up. Wave then arrives and tells TFAWPS that she is returning to Fin-Land, kissing Ted on the cheek and telling them not to let anymore evil entities take over their bodies. Sonic and Ted then meet with Reeces. Sonic says that he thanks Reeces for saving his life, but warns the Masters of Magic not to come near the Land of Ooo anymore. Reeces insists that the work he does here is important, but Sonic says that TFAWPS has it covered, but Reeces tells Sonic that they'll have to agree to disagree on this one, with Reeces teleporting himself out of their HQ.

In the Negative Zone, the Entity tries to return to the Land of Ooo, but realizes that it can't. The Entity calls over two of its heralds, Roy and G. Biv and tells them that it's up to them to infiltrate the Land of Ooo.
