Adrien confronting Ladybug while she's under the effect of Rider Brave's spell and completely devoid of any fear... Including that of killing people.
Ladybug breaking the spell that was put upon her by Rider Brave.
When attacked by Noel after Rider Brave's defeat, Kiva stands up to the much larger teen... And actually manages to defend himself. Badass in it's purest form.
Gargouille
The first mission including Rena Rouge and Carapace: defeating the Gargouille dragon, sending him back in the magical dimension it had emerged from. For reference, Hawk Moth sent an Akumatized champion to try and take control of it... And the Heroes had to save her from the dragon.
Snippets 1
One for an Akuma... As in, the butterfly: At one point Kim had the bright idea to fend it off with a flyswatter, but the Akuma broke it and then yeeted him into a nearby pond.
Zombizou
Mme Bustier briefly fending off an Akuma before being Akumatized.
The day after, Chloé apologizing for everything she's done in front of the class, starting her redemption.
Queen's Battle
When Style Queen shows up, Adrien attacks to hold her off just long enough to let the civilians escape.
The battle against Style Queen is particularly awesome, as not only she's made of gold dust and effectively invulnerable, her magic is so powerful only Ladybug's Miraculous Cure could reverse it... And it got both Carapace's shield and Marinette early, thus forcing a switched team: Adrien wielding the Ladybug Miraculous as the Scarlet Bug, Nino with the Black Cat as Night Prowler... And Chloé's debut as Queen Bee.
Queen Bee deconstructing Style Queen's pretense of being a queen.
Style Queen's defeat: after summoning a tube of glue with the Lucky Charm, Scarlet Bug has Queen Bee swing both her trompo and his yo-yo so fast to suck in things... Such as Style Queen's body after she's hit, before tossing the cut-in-two tube in the mix and trapping her as a formless mass of gold dust.
Scarlet Bug slapping and dressing Audrey down for her response to Chloé trying to help her as a person. Even if it comes too late to keep Hawk Moth from Akumatizing her, it's quite satisfying.
Queen Wasp's defeat: by using one of Rena Rouge' illusions they get her to expose herself... And then drag her in the pool of the Grand Paris Hotel, where the wasps can't help her, with Ladybug and Carapace pinning her down while Chat Noir deals with the Akumatized Miraculous.
When Audrey demands that he disown Chloé for what she did to her as Queen Wasp, Andrè Bourgeois finally grows a spine and instead annuls their marriage. Not merely a divorce, legally it's as if they had never been married. Andre is officially a Papa Wolf who will not let his daughter suffer anymore.
Prince Charming
As soon as he realizes how liked by the girls Luka is, Noel tries to bully him into submission... And Luka just humiliates him by being perfectly rational and nice about the whole thing.
Juleka calling out Alix for tormenting Chloé even as she's not done anything wrong since the Zombizou attack.
Unable to transform due the presence of witnesses, Chloé goes out and willingly pisses Prince Charming off to give Juleka, Rose and Alix a chance to escape while he's coming after her. And then, even after being injured, once everyone's away she transforms to fight anyway.
The debut of the Moth Swarm, holding off four of the heroes and allowing Prince Charming to summon thorny vines and capture them.
Immediately followed by Queen Bee cutting all vines-while injured by having been kicked in the stomach by an Akuma while a civilian.
How the heroes deal with the Moth Swarm before the final fight with Prince Charming: having worked out they're actually butterflies, they lure them away a few at a time with the flashing light app of their tools and beat them up. By the time they reveal themselves there's only one Moth still standing...
One for Luka and Juleka, for actually helping while kept hostage by Prince Charming: Luka points some of the Moths to the flashing lights, and Juleka keeps the one officiating her "marriage" to Prince Charming droning as long as possible to give the heroes more time to cull the Moths. And then, when the Heroes attack openly she throws it in the Seine.
During the final fight, Ladybug's Lucky Charm is a mason jar. She actually puts it to use to trap the Moth Swarm in it after defeating them, preventing Hawk Moth from regenerating them.
Again for Queen Bee, for being the one who defeats Prince Charming... While still injured by the kick she suffered before transforming.
Soccer Mom
The Miraculous Alliance fighting a lightning-throwing living cloud-and winning.
During the fight, the debut of Jinxx, the Kwami of Randomness. The heroes needed a distraction to take out the cloud-and she summoned a rain of spaghetti.
Kwamis cannot manifest in the world without a Miraculous. Unles it is the Kwami of Randomness Jinxx is doing just that, after her Miraculous was destroyed millennia previously.
When Lila and Jinxx reconcile after Jinxx did her runner, and given Miraculous Metal by Ladybug, their bond turns the alloy into a new Bat Miraculous, making Jinxx Lila's kwami, as well as allowing Lila to transform into her own Miraculous hero form, Pipistrello.
The Director
Steeleo
The Akumatized villain turns the building where the Robot Wars take place in a stadium where the heroes are forced to fight the robots of the other contestants, which are turned into MECHA.
Ladybug hijacks one of said mecha, first turning it against Steeleo and later reformats it into a Ladybug mech to beat Steeleo with.
Powerfist
Greg Cipica, to protect his godson Adrien, takes an akuma butterfly that was intended for the latter and hijacks his own Akumatization as Powerfist. Not only that, he is so powerful he can hijack Hawkmoth's footsoldiers with his powers.
Silencer
Feast Hyper
Despite being locked up and weakened from her use of the Peacock Miraculous, Nathalie manages to briefly regain control of the Sentimonster Feast, using those moments to send clues that ultimately lead the heroes to find out Hawkmoth's identity.
