In Hawk Moth's lair...
"I feel a police officer discovering who the Bay Harbor Butcher is, but due to being fired, he has negative emotions within him," the window to his lair opens, as he is ready to make his move to create another supervillain. "My akumas should have a field day on this."
A single butterfly lands on the palm of his hand and he covers it with his other hand, filling it with dark energy. This process converts the butterfly into an akuma.
Once that is done, he lets go of the akuma from his hand, letting it fly away from the window of his lair, ready to akumatize someone with negative emotions.
The akuma enters Doakes' handgun, causing a moth-shaped emblem to appear on his face.
"Congratulations, officer, you cornered the Bay Harbor Butcher," Hawk Moth's voice is heard speaking to him.
"Yes, I did, whoever you are," Doakes spoke next.
"Uh oh..." Dexter realizes he's going to be in more trouble.
"Mr. Detective, I am Hawk Moth," the supervillain speaks sinisterly of his deal. "This man has troubled you enough, so I'll be giving you the power to seek revenge on him for the loss of your job. I'm sure that once you apprehended him, everyone in the Miami Metro Police Department will praise you as the hero who apprehended the Bay Harbor Butcher. In return, bring me Ladybug's earrings and Cat Noir's ring when you cross their paths. Do we have a deal, hmm?"
"Yes, Hawk Moth, we have a deal," Doakes agreed to the deal as black and purple mist started to appear from his gun to cover his entire body.
As Dexter watches this, he knows he's screwed.
Once the mist clears out, Doakes' appearance changed. While he maintains his normal skin color, he now wears a black suit with a yellow fedora and trenchcoat ensemble.
"Doakes?" Dexter tried to call for him.
"My name is Mr. Detective, and you, my friend, are under arrest," the akumatized villain pulls out a larger handgun and points it at him.
"I'm so screwed."
"Yes, you are."
