Violator

"You've been violated, little girlie-man!"

- The Violator's famous cathphrase.

The Violator is one of the main antagonists in the Image Comics Spawn series and Spawn's archenemy. He is a demon under the service of Malebolgia, Mammon, and even Satan himself. He is also one of the Phlebiac Brothers. His true form is that of a demon, but he prefers the appearance of a morbidly obese clown. He also had his own series title Violator with him as the main character. Even though he is technically not the Big Bad, Violator is still the most recurring antagonist of the series.

Comic Book
The Violator is one of Spawn's most recurring and vicious opponents, being a mentor of sorts to the Hell-Spawn he is a arrogant and cruel entity that delights in the pain of others, while naturally a gigantic monster he often took the disguise of an obese clown when interacting with the mortal realm, hence earned his alter ego of the "Clown".

Violator sees murder, torture and depravity as forms of entertainment and holds humanity in contempt, feeling true demons like himself are superior beings, this in part fuels his particularly brutal interactions with Spawn: who he is sworn to serve but still holds in extreme contempt for being a former human.

In recent times he is currently in hell after Al Simmons returns he was stuck in his clown form for quite sometime after Jim Drowning's time as Spawn and he later teams up with Simmions to get power but unknown to Simmions he still had his ability to shapeshift.

Movie
In the live action movie he is the secondary antagonist of the film, Violator works together with Jason Wynn to have Wynn's best assassin, Al Simmons killed.

He was portrayed by John Leguizamo.

Shadows of Spawn
Violator appears as the deuteragonist in anime manga series, where a Japanese-American, is a street thug who hires himself out for money in order to care for his younger sister Mariko, who is very sick. He was known by the nickname Double K. After promising his sister to be with her for her birthday, Ken is murdered by clients. Seven years later, Ken is brought back as a Hellspawn. (It is heavily implied that Ken returned to Earth at the exact same time as did Al Simmons, as many events parallel events in the original comic). Like Al Simmons, Kurosawa initially has no memories, and is confronted almost immediately after awakening by the Clown. Clown briefly leaves the manga, replaced by a faerie-like creature calling herself Beelzebub. He returns as the Violator
