Biography
Stansfield is a corrupt DEA agent who murders the entire family of a girl named Mathilda over a drug dispute, and therefore becomes the target of her wrath when she hires the hitman Léon to help her in her quest to avenge her family.

After increasing her experience with firearms, Mathilda fills a shopping bag with guns from Léon's collection and sets out to kill Stansfield. She bluffs her way into the DEA office by posing as a delivery person, only to be ambushed by Stansfield in a bathroom. Léon, discovering her intentions in a note left for him, rushes to rescue Mathilda, shooting two of Stansfield's men in the process.

Stansfield is enraged that what he calls the "Italian hitman" has gone rogue. He threatens Tony, coercing him into surrendering Léon's whereabouts. As soon as Mathilda returns home from grocery shopping, an NYPD ESU team, sent by Stansfield, takes her hostage and attempts to infiltrate Léon's apartment. Léon ambushes the ESU team and barters one agent for Mathilda's freedom. In the apartment, Léon creates a quick escape for Matilda by chopping a hole in a slender air shaft. He reassures her and tells her that he loves her, moments before the police come for him.

In the chaos that follows, Léon sneaks out of the apartment building disguised as a wounded ESU officer. He is unnoticed save for Stansfield, who recognizes the hitman and shoots him. Stansfield jeers him haughtily. Léon places an object in Stansfield's hands, which he explains is "from Mathilda," then he dies. Opening his hands, Stansfield recognizes it as the pin from a grenade. He rips open Léon's vest to discover several grenades on his chest, right before a massive explosion kills him.
