Chapter 1

Tropes That Appear In This Chapter:

Beware the Silly Ones: While most of Hawk Moth's akumatized villains qualify, it's safe to say that Fairy Grandmother takes the cake. Originally an old lady who wanted grandkids from a daughter that refuses to give them to her, her akumatized form Fairy Grandmother induces a city-wide orgy that traumatizes the entire population and changes the status quo permanently.
Gone Horribly Wrong: To say that Hawk Moth didn't intend on his latest akuma causing a city-wide, magically induced orgy would be putting it lightly. The fact that it made him rape Nathalie and his son rape his classmate just makes it sting more.
My God, What Have I Done?: Pretty much everyone in the chapter has this reaction when the brainwashing wears off. Gabriel for causing it, Adrien, Alya, Nino and Marinette for what they went through while under it.
Not Wanting Kids Is Weird: The Inciting Incident that akumatized Mabel LaCrux into Fairy Grandmother is when her daughter told her that she doesn't intend on having kids.
