The scene begins by showing an old box with a red symbol on it.
"A very long time ago magical jewels named Miraculous appeared. They grant the wearer incredible powers…"
The scene follows heroes from the past who received Miraculous and use them for good.
"They both are the most powerful. The ladybug grants the power of creation and the cat that brings destruction. When united, it grants their wearer the power to grant a wish.
The scene changes to a lair in an unknown location with several white butterflies.
A man stands in the middle of the room with a creature resembling a pale purple butterfly.
? : Nooroo tell me again what is the power of the Miraculous of the Butterfly?
"He gives you the power to create your champion." Nooroo explains.
? : Interesting. Create a champion who sows chaos. Ideal for attracting superheroes.
"Wait, what? Master…"
? : Nooroo, wings of the night!
The butterfly's Kwami is sucked into the object, the butterflies surround it and transform it into a supervillain.
"Now I just have to wait for a negative emotion to kick in."
The scene changes for Royal Wood Elementary School.
Lincoln and Clyde walk to attend their first class.
"Class. Today we will have two new students. One more to come today. You can come in." Mrs Johnson announces.
A young girl with blue hair entered the classroom with a yellow box.
"Hello, my name is Marinette Dupeng-Chan. My parents opened a bakery in Royal Wood and I brought a specialty, macaroons." When opening the box, appear multicolored macaroons.
Marinette hands out to each of the students and to the teacher.
"That's very nice, Marinette. We're going to resume yesterday's class." The red-haired lady wrote on the board.
Chandler throws a ball of paper at Ivan's desk. The muscular boy reads it and gets angry.
"Chandler!"
"Ivan, why is it angry?"
"This is Chandler, he deserves to punch him in the face."
"Ivan, violence is prohibited here. Go to the principal's office."
Ivan is still angry with Chandler. He leaves the classroom with the ball of paper in his hand.
His negative emotions are felt by Hawk Moth.
"One student is angry with another. This is my first creation. Fly away little Akuma and blacken his heart."
The man in purple dresses blackens a white butterfly with evil energy and makes it fly out of the window of his lair.
At the same time. Ivan is in front of Principal Wilbur Huggins' office. Ivan knocks loudly on the door and enters.
"Have you ever been taught to knock on the door, young man? Come out and do it again." Wilbur Huggins told him.
Ivan growls and leaves. At the same time, Akuma is absorbed by the paper ball in his hand, and Ivan transforms into a stone golem.
In his office, Wilbur is waiting.
"So, are you knocking on the door?"
StoneHeart destroys the door with his force.
"Chandler !"
The golem returns to the classroom, destroying the wall in front of him.
"Chandler !" The creature says with Ivan's voice.
"Ivan ?!"
Chandler runs as fast as possible to escape the monster.
"Class, that will be all for today. Go home and take shelter." Mrs. Johnson told her students.
They all go home.
"Talk about the first day of school."
"Yes, and how did Ivan turn into a monster?" Clyde wonders.
"I don't know but if it was in Ace Savvy's universe, I was betting on a villain who has the ability to turn people into monsters."
The two arrived at Lincoln's house.
"No doubt. See you tomorrow."
"Yes."
Lincoln walks into his home, sees his family watching the news.
"Here, Katherine. A stone monster destroys everything in Royal Wood. He is in pursuit of a young boy who tries to escape the monster."
"Chandler !"
"The police are trying to stop the monster."
The cameraman films the policemen who try to stop the monster but they fail because the monster is too strong.
"Lincoln, that monster with the voice of one of your classmates?" Lori asks Lincoln.
"Yes. I don't know how but Ivan is turning into a monster."
"The most important thing is that everyone is safe."
"Yes. Until that passes, I'll be in my room reading the new Ace Savvy I ordered online."
Lincoln goes to his room, sees his comic book next to a mysterious box. At the same time, Marinette and Adrien received one too.
"What is that? He hadn't mentioned a surprise in it." Lincoln opens the box and a luminous white ball flies around him.
The light dissipates and reveals a small white creature with the card symbols on its head and arms.
"Greetings Lincoln Loud, I am Ace Diamonds, the Kwami of the ally."
"Kwami? Ally? I bet that's a Luan prank. Lua -"
"No! Your family must not know that I exist. It's for your safety and that of your family." As Carreau explains.
"Ok, I'm not going to say anything. But why are you here?"
"Like I told you, I am a Kwami. A magical creature that gives powers to its bearer in order to stop the villain. Your special power: is called Full Deck, allows you to randomly summon one of the Full Deck characters , after that you don't have five minutes before you detransform. "
"Wow. And transform me?" Holds the Ace of Diamonds card in hand.
"You just have to say, let's play."
"Let's Play!"
"Wait, I haven't -!?" The white Kwami is sucking into the card.
Lincoln's clothes change into a red and black suit with the red Ace of Diamonds symbols. A black mask appeared on her face and her hair turned black.
"Too cool. Ace now like I'm back to my way? Ace? I guess I have to wait until the time is up? What do I do during this time?"
Lincoln wonders but hears through his bedroom window the voice of Ivan chasing Chandler near his neighborhood.
He plays the hero, comes out of his window and jumps from roof to roof towards the source of the voices. Along the way, Lincoln meets two other heroes. They follow the Stone World to Royal Wood Stadium.
"Hi, are you one of my teammates from my Kwami talking to me?" The cat hero asks.
"Yes, I am Ace De Roi."
"And you?"
"Marin- Ladybug." She tries to wield her yoyo.
"My Kwami told me that I must capture akuma."
"He's got nothing on him."
"Her hand?"
"You're right. He keeps it closed all the time."
"So how are we supposed to stop him before he runs over this boy?" Cat asks.
"My Kwami to mention special powers."
"Let's try them!"
"Wait, don't do it…."
"Cataclysm!" The hand of the hero cat is concentrated with destructive energy. "I can destroy everything by touching it."
He tests his power on the stadium goal which crumbles to dust.
"Prepare to turn to dust again!" Cat rushes towards the enemy, touches them and nothing happens.
Stoneheart hits him and sends him across the stadium.
"Apparently our power is to be used together. It's only the two of us left. Lucky Charm!" Its power conjures up a wetsuit.
"Full Deck !" His Full Deck character cards fly away in a whirlwind and one of the heroes is selected: Deus.
The superhero looks like Lily who appeared.
"Poo-poo!"
"Seriously?"
"Poo-poo !" Deus threw tons of dirty diapers at Stoneheart.
The villain can't stand the smell of his diapers.
"What a smell! How can a single baby produce a stench like this?"
"Poo poo." Deus bombards the stone monster with a layer around the room.
During this time. The Ladybug superhero is trying to figure out how to use the item her Lucky Charm gave her a wetsuit.
She attaches a balloon pump to the suit and frowns on the enemy, purposely getting caught. Triggers the machine. The jumpsuit swells in his hand and Stoneheart drops the ball of paper.
The ladybug girl breaks the paper ball. Ivan goes back to being as before with no memories having happened.
"Where am I? Why am I at Royal Wood Stadium?"
"Everything is fine Ivan."
"How do you know my name?"
"That…" Her earrings start to beep.
The ring and the card too.
"I think it's time to go."
The three heroes go their separate ways. Lincoln returns to his room and deforms.
"Wow! That was great. We defeated a real villain."
"Yes and the akuma was captured right?" As Lincoln Asks.
"The what?"
The scene changes to Marinette's room. Tikki explains the importance of capturing the Akuma.
"So the black butterfly I saw came out was the Akuma?"
"Right. You have to capture it, otherwise it might multiply." Tikki explains.
"I made a huge, big mistake."
At the same time. The black butterfly multiplies in several ...
