Synopsis
Late at night, Zack, Agent Yellow, and Bart pilot a helicopter scouring the Land of Ooo for the shard, while Agent Yellow and Bart argue over the radio station. While they search, Mega Man flies towards them and starts firing blasts at them. As they dodge Mega Man, Oscar and Phoebe latch on to the underneath of the helicopter trying to get them to land. Agent Yellow fires lasers at Oscar and Phoebe knocking them off the helicopter, but Mega Man catches them and they continue their chase. Bart jumps out of the helicopter, transforming himself to give him wings and chases after Mega Man. Oscar and Phoebe then team up and take down Bart. As Oscar, Phoebe, and Mega Man chase down attack Zack, two rainbow blasts knock Zack out of the city. Turning around, they are greeted by Roy and G. Biv who tell them they need help. From space, Genesect looks down on them and tells himself that he has found the one he seeks.

As Zack makes his way back and everyone gets into a battle formation, Phoebe asks the Rainbow Twins what they're doing here and they tell her that he's coming back and soon. Zack then tells the Rainbow Twins to give him more time and Oscar asks what he means by that and the Roy says they'll explain later, they just really need to get somewhere safe. Mega Man then ambushes Agent Yellow and tells him it's time for some payback. Mega Man takes Agent Yellow and dribbles him like a basketball down the street, as revenge for hypnotizing him. Zack then electrocutes the Rainbow Twins and takes them hostage, escaping Oscar, Phoebe, and Mega Man

In Zack's Lair, Zack interrogates the Rainbow Twins, who are trapped in the same device they had previously used to drain Ted's power, asking what the Cosmic Entity wants from him now. He says that he's trying his best to locate the other shard and he should hold off his invasion for just a bit longer. The Rainbow Twins retort saying that they don't work for the Entity anymore, but they're here to warn everyone here that the Cosmic Entity plans to completely destroy the Land of Ooo. Zack says that he's aware of that. The Rainbow Twins then break free from their chamber and blast Agent Yellow and Bart away. The Rainbow Twins then give Zack a chance to escape the Land of Ooo, but Zack says he can't and the Rainbow Twins escape. Zack then leaves his HQ.

At TFAWPS Tower, Oscar, Phoebe, and Mega Man report what they've learned last night to Sonic. Sonic says that they have to prepare an offensive, but Phoebe insists that they need to evacuate the city instead. Mega Man says that when Mario hears about this, he will for sure evacuate the Land of Ooo. Suddenly, the Rainbow Twins burst in, chased by Pink Panther, Ted, and Paco. Oscar stops them from attacking and they give the Rainbow Twins a chance to explain. G. Biv says that they used to be heralds for the Cosmic Entity, meaning they would travel to worlds that the Entity wanted an announced his arrival. He tells them that Frieza is a herald as well. Sonic asks them why all of a sudden to they have a change of heart and Roy explains that it was the only life they've ever known, but once they encountered TFAWPS, they had a change of heart and rebelled against the Entity. Still unsure if they're trustworthy, G. Biv says that whether they trust them or not, the Entity is coming for the Land of Ooo and they need to do something about it.

At his Castle, Pig King returns with Master Robot to find their castle in disrepair. Pig King then orders Master Robot to fix the leak, while Pig King feeds Gunther and Tyler who have been without food for several days. Suddenly, there's a knock at the door and it is revealed to be Genesect. Pig King is confused and asks how he got unfrozen, but Genesect blasts Pig King into a wall and subdues Master Robot with his new cosmic powers. Pig King asks Genesect what he wants and Genesect says that he's having company visit the Land of Ooo and once his company arrives, Genesect will be in charge and will need a place to rule over his new colony of slaves and he says that this castle will do. Pig King refuses to give up his castle and tells Genesect he'll just have to find a new building to claim, recommending TFAWPS Tower or City Hall. He refuses and locks Pig King in a closet.

Sonic travels into space with the Rainbow Twins, Paco, Mofo, Buster, Oscar, Phoebe, and Lupina to do deep space scans for any signs of the Entity. Lupina says she's not finding any evidence of a cosmic disturbance, but the Rainbow Twins inform her that the Entity is made of pure cosmic energy and is untraceable against the vastness of space. Suddenly, they are approached by Frieza, who motions them to land on a nearby moon. Frieza says that they should prepare for the end and that he's here to welcome the Entity to the Land of Ooo so that he can destroy it. He then confronts the Rainbow Twins saying he knew they never had the guts for this business and that they should count themselves lucky that he found them before Genesect did as he'll make their deaths quick, but Frieza discounts Genesect saying that all he cares about is vanity. Frieza then calls forth an army of Negative Zone Soldiers and Sonic prepares his team for attack.

Meanwhile, Mega Man gets to work with Mario and a bunch of S.E.C.R.E.T. agents to finish the work on his ship, the Starcaster. As they work, Genesect announces to the Land of Ooo that they have less than an hour remaining before their world is destroyed and tells them that they only have TFAWPS to blame. The Mayor urges the citizens to disregard that announcement and orders everyone to get on the Starcaster quickly. Pink Panther reassures the citizens that they will protect them no matter what and calls Ted and Wally with him to make sure everything is okay.

Back in space, Sonic tells Frieza that this is where the Land of Ooo will make its last stand he'll do anything to protect his home from the Cosmic Entity. Suddenly, a portal begins opening up behind them and Frieza informs them that it's time. Frieza says that they'd go easy on them, but traitors don't deserve mercy and begins to attack, but he is immediately hit by a rainbow blast, signaling the start of the battle. TFAWPS rushes into action against the soldiers, hitting them with all they've got. As they keep fighting, the Rainbow Twins have their own private battle with Frieza each trading insults back and forth. Just as the Rainbow Twins land a hit, the portal opens and the Cosmic Entity begins making his way towards the Land of Ooo and Frieza calls Genesect to inform him that the heralds' jobs are done and it's time to begin the eradication. The Cosmic Entity then begins pulling everything into the Negative Zone, much to Frieza's satisfaction.

At Zack's Lair, Agent Yellow, Bart, and Dr. Robotnik are just sitting around until Zack enters his facility. The three lackeys stand at attention, but Zack tells them to sit down. Zack tells them that he had no luck finding the shard and now it'll be too late. Agent Yellow asks what they do now and Zack gathers up his shard and tells them that he's getting out of there, just as his Lair is pulled into the Negative Zone.
