Characters: The Professional
Leone "Léon" Montana
Played by: Jean RenoA mysterious assassin living alone. He ends up 'adopting' his young next-door neighbor after her family is murdered.
- Adorkable: Just look at him watching movies and playing with Mathilda.
- Anti-Hero: He's a decent enough guy. But he still makes a living by killing people.
- Badass Longcoat: Covering an even more badass rig for his pistols, silencer, spare magazines, grenades and bolt cutters.
- Book Dumb: He can't even read before he takes in Mathilda.
- Celibate Hero: Has not had a girlfriend since his last one died in the old country.
- Consummate Professional: Proficient with everything from his bare hands to explosives, doesn't drink alcohol, doesn't leave witnesses or evidence, lives off the grid, doesn't form emotional attachments and, aside from occasional trips to the cinema and tending to his plant, seems to have no life at all outside of professional killing.
- Cool Shades: Some badass circle shades.
- Dying Moment of Awesome: Léon's death scene counts — especially since he takes Stansfield with him.
- Everyone Has Standards: "No women, no kids."
- Hitman with a Heart: Reluctantly at first, but eventually warms to and becomes a protector of Mathilda.
- Loners Are Freaks: Before meeting Mathilda.
- Trademark Favorite Food: Gotta have his milk.
Played by: Natalie PortmanAn intelligent and tough young girl who becomes Léon's protégée following the death of her family.
- Bodyguard Crush: Mathilda has one of these for Léon.
- Cynicism Catalyst: Mathilda doesn't give a damn about the rest of her family — but the bastards who killed her little brother must die.
- Hot For Teacher: Develops a crush on Leon.
Played by: Gary OldmanA corrupt DEA agent on drugs who slaughters Mathilda's family.
- Cowboy Cop: A rare villainous example.
- Dangerously Genre Savvy: Manages to outwit the protagonists on several occasions, getting the drop on both Mathilda and Leon at separate points in the film.
- Dirty Cop: They don't make 'em much dirtier than this. Is involved in drug running (and apparently likes to sample the product) and will kill just about anyone who gets in his way.
- Hair-Trigger Temper: Reacts to an old woman asking him what he's doing by shooting at her. This is pretty much par for the course for Stansfield.
- Hand Cannon: Packs a snubnose .44 Magnum.
- Jerkass: His own men could hardly stand working alongside him.
- Knight Templar: Obviously.
- Large Ham: Oldman delivers a wonderfully over-the-top performance, to the point where some people consider him to stray into Narm territory at points.
- Rabid Cop: One of the worst in Western cinema. Makes Harvey Keitel in Bad Lieutenant look like Corporal Carrot.
- Sophisticated as Hell: While discussing the beauty of Beethoven, he has a "creative" way of discussing the composer's shortcomings.Stansfield: So powerful... But after his openings, to be honest, he does tend to get a little fucking boring.
- Villainous Breakdown: EEVVVERRYYYYONNNEEEE!!!
- Wicked Cultured: He is a fan of both Mozart and Beethoven, especially Beethoven. Brahms too.
- Would Hurt a Child: Very nearly kills Mathilda - and implies that he'll enjoy doing it - before being stopped at the last minute by news of the death of one of his subordinates.
