Series
- Nathalie Sancoeur is Gabriel Agreste's assistant in his business and his supervillain endeavors as Hawk Moth to steal Ladybug and Cat Noir's Miraculous to revive Emilie. She facilitates his plan on Heroes' Day by allowing herself to be Akumatized into Catalyst to boost his powers and let him Akumatize many people at once. When he is on the cusp of defeat, she uses the Peacock Miraculous to help him escape, despite the risks to her health. As Mayura, she creates Sentimonsters to supports the Akumatized villains in battle with Ladybug and Cat Noir, and she aids Hawk Moth in various plots. When Gabriel benches her due to the Peacock Miraculous deteriorating her health, she went against orders and created a Sentimonster copy of Ladybug and staged a fight with her to trick him, then erased her when Ladybug took her Amok. When Gabriel steals most of the Miraculous and becomes Monarch, Nathalie advises him to go back in time and give his past self the information to fix the Peacock Miraculous before it was used, then realizes how obsessed he was when he chooses to instead fight the heroes and loses that chance to save her and Emilie forever. She stays with the Agrestes and keeps half of Adrien's Amok to protect him from his father and prevent Gabriel from interfering with his love life. Learning that Gabriel is dying, she lets herself be Akumatized into Safari so that she can get the Miraculous and make a wish herself, nearly succeeding. Loyal to the Agrestes, she carried out her missions calmly and efficiently while avoiding the mistakes that Gabriel made.
- Lady Wifi is the Akumatized form of Alya Césaire, who wishes to expose Ladybug's identity. Wifi broadcasts Principal Damocles confessing he wrongfully punished Alya, then unmasks Chloé Bourgeois in a Ladybug costume. Pursuing the real Ladybug, Lady Wifi is able to avoid the heroes' attempts to trap her, as well as repeatedly luring the heroes around the hotel by restricting their movements through locking doors. Wifi would have removed Ladybug's mask had it not been for magic adhesive, and opts to make Ladybug detransform by forcing her to use her Lucky Charm to save a trapped Cat Noir. Wifi anticipates the heroes neutralizing her powers by destroying the wifi antennae, and is only defeated due to Cat Noir's faster speed. She returns as part of The Punisher Trio looking to get revenge on Félix Fathom, and later as a member of the Gang of Secrets to unearth the truth about Marientte, where Wifi's inherent goodness allows her to dispel her Akumatization on her own.

A theatrical Master Swordsman, Darkblade tactically lulls his opponents off guard by dropping his own guard and then laying both arms spread eagle at his sides in order to trick them into charging so he can defeat them head on. Turning the people of Paris into his knights, Darkblade is able to conquer and respond to any issues by using his minions as clever weapons or equipment. When the doors to city hall are barricaded, Darkblade uses a catapult to spring himself to the top so he can plant his flag and claim the city magically as his own.

Returning after his first defeat, he upgrades himself to Gamer 2.0 and captures all previous Akumatized villains to play a massive gaming tournament against the heroes while keeping them on their toes. After being defeated, Gamer 2.0 accepts his defeat gracefully while showing genuine respect to Ladybug for a game well played.
- "Simon Says": Simon Says is the Akumatized form of Simon Grimault, a hypnotist who was shamed on live TV. As Simon Says, he possesses the power to hypnotize anyone by throwing his special cards. Seeking to get revenge on Gabriel Agreste for humiliating him, Simon Says uses a brainwashed army of civilians to attack the heavily fortified Agreste mansion, managing to break past both the defenses as well as Ladybug and Cat Noir, and successfully kidnaps Gabriel. After hypnotizing Gabriel as revenge, Simon Says uses Gabriel as a hostage to make the heroes hand over their Miraculouses, and when they refuse manages to break Ladybug's magic yo-yo. Had it not been for Ladybug's Lucky Charm granting her a second yo-yo, Simon Says would have almost certainly won.
- "Robostus" & "Hack-San": Robostus is the Akumatized form of Max Kanté's robot Makarov. Tricking Hawk Moth into revealing that the combined powers of the Miraculouses will allow him to gain a reality warping wish, Robostus plots to use it to become human and be with his friend Max. Using his ability to control and bring life to technology, Robostus overthrows and takes over Paris. Robostus lures Ladybug and Cat Noir into a trap by intelligently boxing them in and later stops and contains Ladybug's Lucky Charm, which could be used to stop him. Returning after his first defeat, Robostus brainwashes the Parisians into giving him the thing they cherish the most, hoping that he'll claim the Miraculouses. When that plan fails, he instead uses them to lure Scarabelle and Cat Noir into a trap, managing to successfully corner the heroes. Making a deal with them to return the objects he's stolen in exchange for their Miraculouses and Scarabella's Luck Charm, Robostus comes very close to winning and only loses due to a surprise attack by Marinette. Usurping Hawk Moth by turning his weapons against him, Robustus proves one of the most competent and dangerous of the heroes' foes.

The trap is whipped cream which is too thick to allow breathing, but is not thick enough to be able to swim through unless they give up their Miraculouses to him. Able to go toe-to-toe with the heroes despite only having technology, he intelligently ensures his Akuma, which can be used to turn him back to normal, is not on his person. Returning as The Darker Owl after his first defeat, he takes Marinette's friend Socqueline hostage in order to lure out the heroes and manages to trap them within a Lotus-Eater Machine by utilizing the powers the Pig Miraculous.
