Silvia, with a determined look on her face, stood her ground, and threw her yo-yo into the air, exclaiming, "Lucky Charm!" A ball and chain appeared before her, and landed on the ground with a loud thud; not wanting to get hurt, Silvia leaped into Marinette's arms, frightened. "A ball and chain...? What am I supposed to do with this?" Silvia asked. "Trust me, Silvia, it's like that all the time. You never know what the Lucky Charm will give you," said Marinette. "Do you have any ideas?" asked Joe. Silvia looked at the ball and chain, and noticed it had an ankle cuff on it. She then looked up at Alastor. "I have an idea, but I don't know how I'm going to do it," she said. "Any idea is better than none," said Adrien. "And you better hurry with figuring out how to do it!"
The lightning began to strike, and the group scattered frantically across the school, avoiding the lightning. While running, she looked up at the roof of the school, and suddenly, it all made sense. "I've figured it out!" Silvia shouted in excitement. The four of them gathered around as Silvia explained the plan. Alastor, meanwhile, was gathering all of his energy, and created a giant sword. "Killing two birds with one stone, are we?" asked Hawk Moth, intrigued. "Or, in this case, four."
Alastor dove down, intending to defeat the quartet with one fell swoop; Adrien, however, noticed the sword, and shouted, "Jump!" The four, on cue, jumped to avoid the slash, and Marinette kicked Alastor out of the way. He tossed the sword away, and angrily flew up to the sky, intending on creating another tornado. "If we're gonna do anything, it better be now, Silvia!" said Joe. "Right!" Silvia agreed. "Everyone - split up as planned!"
Adrien and Silvia took off in one direction, and Joe and Marinette took off in another. Alastor frustratingly watched them hide in the building, declaring, "You can't run forever, punks! I WILL have the ultimate battle!" Suddenly, Marinette and Adrien appeared opposite to each other on the roof of the school, and Marinette said, "Sorry, Alastor, but this ultimate battle is coming to an end." "And the winner is - us!" finished Adrien. They then leapt in the air, attacking Alastor from both directions, and shouting "Red Hot Kick!" and "Cool Blue Kick!" in sync. Alastor laughed. "Do you never learn?" He flew upwards, leaving Marinette and Adrien to crash into each other. Silvia, however, leapt upwards off of Adrien and cuffed Alastor's leg with the chain. "Oh, we learn," said Silvia. "We don't repeat the same tactic twice!"
The weight of the ball and chain harshly pulled Alastor back down to ground level, and Alastor could not get himself free. He angrily looked at the cuff, and almost destroyed it, before Joe came out of nowhere and shouted, "Cataclysm!", destroying the skull on Alastor's head. "No!" shouted Hawk Moth from his lair. Alastor returned to normal, and a little black butterfly flew away. "And now, you have to capture the akuma!" Marinette said. Silvia nodded and said, "No more evildoing for you, little akuma." She opened her yo-yo and flung it at the butterfly, shouting, "Time to de-evilize!" The butterfly was caught by the yo-yo, and Silvia, grabbing the yo-yo, said, "Gotcha!" She then opened the yo-yo again, and a white butterfly flew out instead, and Silvia said, "Bye bye, little butterfly!"
"Ugh...what happened?" Alastor said, in a confused state. "And why are you two dressed as each other?" "You were akumatized, and you turned into this big demon!" said Joe. "You made this big tornado, and we ended up having to swap powers!" explained Adrien. Silvia remembered something. "Oh, right! Before I forget:" She unhooked Alastor from the ball and chain, and threw it up into the air. "Miraculous Ladybug!" The damage to the school disappeared, and Adrien, Marinette, Joe, and Silvia detransformed. Silvia and Joe handed the earrings and ring to Marinette and Adrien, and Adrien and Marinette handed the watches back to Joe and Silvia. The rest of the school came out cheering. "Good thing we got our items back before anyone else noticed," Adrien whispered to Marinette. They quickly hid their kwamis from the crowd.
"You did it, guys!" Kim said, in excitement. "It was so cool, it was almost like a real life movie!" He pulled out a piece of paper and a pen. "Can I have your guys's autographs?" he said, handing the items to Joe and Silvia, and they happily obliged. Kim then handed the piece of paper and pen to Alastor, who looked confused. "But...I'm the bad guy," he said. "True, but you were still the star of the show! You looked so cool, even though you were akumatized! And I love your work in the Viewtiful Joe movies too!" Kim explained. Alastor, touched, quickly took the piece of paper and scribbled on it, before handing it back quickly; he didn't want to have anyone know he was being emotional.
Hawk Moth, in his lair, was very upset. "Keep celebrating all you want, Ladybug and Cat Noir. But it won't be long before we have OUR ultimate battle!" His lair closed.
Max and Markov entered from the crowd of students. "Oh, Max! How did making the portal go?" asked Marinette. "It was a huge success!" Max said enthusiastically. "With the help of the students who fled to the science lab, we were able to build it in no time!" Markov said. Max turned it on, and it showed a city with signs saying "Movieland" on them - it was Joe and Silvia's home.
Joe suddenly had an idea. "Say...would you two like to come into our world for a quick minute?" Marinette and Adrien looked at each other. Adrien, being the fan of the Viewtiful Joe movies he is, nodded eagerly. "Sure!" said Marinette. The four walked into the portal, and Marinette and Adrien were blown away by how cool the city looked. A whoosh was heard, and the four looked off to see Alastor flying away.
"Well, I guess this is goodbye," Joe said. "It was fun teaming up with you two!" said Silvia. "I couldn't agree more," said Marinette. "We'll definitely call you if we need some help over in Paris," said Adrien. The four of them fist bumped, and said, "Pound it!", before Joe and Silvia walked away, and Marinette and Adrien walked back into the portal.
Joe and Silvia were walking through the city, when they walked by a store with action figures inside; two figures quickly caught Joe's eye, and he gasped, pulling Silvia towards the window. "It's them!" said Silvia, recognizing the figures. "Ladybug and Cat Noir! I didn't even know this store had them!" Joe quickly ran inside to purchase the figures for himself.
"You know, I'm really going to miss those two," said Adrien. "Would a date to the movies make you feel better?" asked Marinette. "I hear Viewtiful Joe is playing this evening!" "You just read my mind. I'd love to join you, m'lady," he said, winking. The two then made their way to the theater.
