As Ladybug and Cat Noir talked on Le Grand Paris rooftop, the crowd that had gathered below were still astonished by the new heroes, who were waiting for the duo to return.

"I'm going up." Birdy launched an arrow with rope attached into the wall near the top and into the middle of his bow. Birdy retracted the rope, so it pulled him up. In the crowd, Alya took advantage of the quiet.

"Are you new heroes who form a team with Ladybug and Cat Noir?" The Ladyblog manager shouted. The heroes looked around, but could not see her. Alya started shoving people to get in front of the crowd. "Excuse me. Sorry. Make way, please." Alya reached the front of the crowd. "Alya Césaire. Creator of the Ladyblog."

Mercury zoomed in to be right in front of Alya. "Mercury. And no, we're not on a team with Ladybug and Cat Noir. Been there, done that."

"Uh... What do you mean 'been there, done that?'" Before Mercury could answer, Cat Noir, Ladybug and Birdy landed on the ground, giving Alya the chance to ask about Cat Noir's outburst. "Ladybug, Cat Noir! What was that all about? Was Cat Noir under mind control again?"

"No, Alya." Cat Noir answered. "I was just angry, not thinking straight."

"Does it have to do with the break-in at the Paris PD?"

"Yeah. But that's all you're getting from me."

The superheroes walked to speak with the adult heroes.

"You must be the associates of... our predecessors." Ladybug guessed.

"Correct." Melodie answered. "I am Melodie."

"I am Mercury." Mercury introduced himself. Mime walked up and stood next to him, smiling, but remaining silent.

"This is..." Melodie hummed. "Well, we used to call him Kid Mime, but he isn't a kid anymore. Just like mimes, he can't talk. Not when he's in costume, anyway." Mime smiled and waved. "We're here to find one person: Hawk Moth. We heard about the Police Department and we can track his Miraculous. Birdy, you got the device?" Birdy pulled a device out of the packet on his leg and tossed it to Melodie. Melodie activated the device and its screen switched on with a beeping purple dot. The dot was shown to be in Le Grand Paris. Ladybug panicked.

"Everyone, get out of here! Hawk Moth's inside!"

"But you took his power source!" Alya objected.

"And Fire Ant took it back." Everyone started running in panic with the knowledge that one of France's most wanted criminals was inside the Parisian Mayor's hotel...

Inside the hotel itself, an elevator stopped on the 11th floor. Nathalie Sancoeur was in the hallway near door number 32. As the elevator opened, Nathalie turned to see who it was.

"Mr. Agreste?" Nathalie said. "I didn't see you go out."

"I can be stealthy." Gabriel retorted. "The hotel's being evacuated. Hawk Moth's come for me."

"What?" Nathalie was scared. "Then we need to get you out of here."

"Not without Adrien." Gabriel walked into the hotel room. Observing the room, the layout was immediately apparent. The 'living room' was right in front of Gabriel. There was a velvet red couch and two chairs of the same velvet surrounding an oval glass table. To the left was a double bed and to the right was a door leading to a kitchen. Gabriel reached inside his pocket and grabbed something, clenching it in his fist. He heard someone in the kitchen, and snuck to the side of the door, peaking in. The person was holding a book. Grinning, Gabriel hid as the figure walked out. When the figure walked out, Gabriel grabbed them and pressed his previously clenched hand onto the book. The book was smothered by the black and purple aura... of an akuma. The figure stood there, frozen. Gabriel referred to them by their name.

"Gabriel Agreste." 'Gabriel' said. "You and the Quantic Kids took my wife and daughters when you killed Blitzwolf. Now, you've already lost your wife, and your son has stolen from you. Your book of inspiration's been taken by the person you should trust most. Now, I give you the power build a new one. Maybe you'll pick up a Miraculous on the way." The frozen Gabriel stood there, trying to fight the rage. His fight was in vain as the aura ensnared him and changed him. His skin was now pale purple. His hair now white with black vertical stripes, along the back of his head and his neck being black as well.

He wore a black dress suit with a white lapel, stiff shoulders, and black and red downward-bent stripes on the front. Each lower sleeve had a white stripe, and his hands now bore white gloves. He also wore black dress pants and high heel boots connected to the pants, and the boots are black with black and white striped heels. The Gabriel that attacked spoke again. "Dark Wings, Rise." At that point, Nooroo shot underneath his scarf and he transformed into Hawk Moth. "What's your answer?"

"The one thing I had left of my wife has been stolen from me. The one who took it will be a fine addition to my new portfolio. Gabriel Agreste is gone. I am... The COLLECTOR!"
