Walter White
Breaking Bad · 2008
The show was pitched as turning a protagonist into an antagonist, and it delivered without a single episode where the change is obvious. That is a structural achievement nothing else on television has matched.
The advantage of serialized television is time. A film villain gets ninety minutes to make an impression; a television villain can spend three seasons quietly becoming someone else. That produces a specific kind of antagonist, one built on accumulation rather than revelation, and the best examples on this list are characters whose worst moments are set up years in advance.
How this list was scored. Scored on use of long-form structure (35%), performance consistency across seasons (25%), how much the show depends on them (25%) and influence on television writing (15%).

Breaking Bad · 2009
The most controlled villain the medium has produced. He establishes total authority in one wordless scene and never needs to do it again.
The Sopranos · 1999
The character that made prestige television possible. Every morally compromised lead of the last twenty-five years is downstream of him.

A superhero body with the emotional development of a lab-raised child, played with a permanent sense that he is one second from breaking.

The series uses a mind-control power to interrogate consent and coercion, and it never once lets the charm excuse anything.

She loses constantly and keeps escalating until the board resets. Her solution to being cornered is one of television's most shocking single acts.

Eight seasons of buildup and not one line of dialogue. As a piece of pure visual antagonism he was extraordinary, whatever you think of the resolution.

He arrives with a functioning system in a world that has none, and the charm is doing exactly as much work as the bat is.

An assassin written as a full character rather than a threat, with a performance that shifts accent, register and mood inside a single scene.

The first antagonist in his series who can speak, and he attacks through grief. The result was a genuine cultural moment built around a 1985 song.

Effective precisely because he has no philosophy at all. He was written to be hated and the show never asked for sympathy.

Not competent, not clever, and still one of the most reviled characters ever broadcast. He proves that a villain does not need to be good at anything.
