Inspector Javert

Inspector Javert is a policeman who is the "antagonist" of Les Misérables. He's also Agent Maria Falcone's lust object

Character History
He's an extremely dedicated policeman who only lives by the word of the law. For most of the book, he chases Jean Valjean around after recognizing him from his own days as a prison guard. Has the interesting habit of showing up just about whenever the plot calls for conflict. He's also known for his creepy smile and his respect for clergy, though he's not particularly religious himself.

He's the same in the musical, although he's more religious there. Whether or not the Inspector is a religious man is one of the many, many things Maria and Michel fight about.

In Badfic
He's either slashed with Valjean, is the story's Designated Douchebag, or is the lust object, often romancing women several decades his junior. Agent Michel Javert is his uncanonical son.
