Sweeping Away Villains in American TV Shows

In an American crime drama, I awaken a System.

Reborn in the land of the free, I become an undercover agent and awaken the Villain Sweep System.

Punishing villains lets me gain experience, attributes, skills, and all kinds of items from my targets.

From then on, American-style Wing Chun is at my side, and I stand against evil with all my might!

Fight crime, sweep away villains, and restore peace and order to the land of the free!

This guy sells drugs, disturbs the neighborhood, and robs homes. He can't be allowed to live!

This guy carries a deadly weapon and is guilty of heinous crimes. He can't be allowed to live!

This guy stares at the sun and clearly has rebellious ideas. He can't be allowed to live!

This guy can even eat and drink on his own? His intelligence is at least as high as mine. He can't be allowed to live!

Brawling in the street and damaging public property, recklessly speeding and obstructing traffic, using martial arts to break the law and endangering bystanders, damaging national defense equipment and threatening public safety...

You're all coming with me!

And you alien species, every one of you better behave!

No crime or violation of the law can escape my keen eyes!

I am the nemesis of evil. I will set things right, and I speak for justice!

And you, inciting a world war and destroying international order. Your crimes are heinous, and you deserve to die!

When did I become the greatest villain in the Myriad Worlds?
