He is a being built of necroplasm, ego and lies. If there was an "older-child
syndrome" he'd have it in spades. He is one of the five "famous" Phlebiac brothers,
demons all, servants of the Malebolgia. His purpose is to guide Hellspawn towards
  fulfilling their master's desire: to cultivate evil souls on Earth. But, because of
jealousy, the Violator is doomed to fail. This is his own particular torment.

He claims to have been born from the magic of Dr. John Dee in the 16th century,
and yet he has dealt with a Spawn in the Middle Ages, four hundred years earlier.
His true origin is lost in the mists of time and the fumes of Hell. He brags that he
  could destroy a Spawn, to its very face, and then whines when the battle turns
against him. His fighting is vicious, born of a dog-eat-dog Hell, but not strong
  enough to overcome his master's pets. The Violator is a contradiction both in form
and substance.

   For eons he has been a poisonous, dripping-fanged, spindly, terrifying, spiked
demon with a weakness for the taste of human hearts, and it's gone to his head. He
has been granted immense powers by his lord, and he simply abuses it, through
ignorance and apathy. Sometimes he appears in his Clown form, which was a joke
he's long forgotten. However, he is now stuck in that configuration. The
Malebolgia took away his shapeshifting powers to punish him for his over-zealous
approach to training Al Simmons. The Violator is dangerous nonentheless. He is a
   yapping chihuahua with shark's teeth, a tiger with the brain of a squirrel, a chimp
with a gun.

He believes that one day his service to the Malebolgia will be rewarded. He believes
that he'll get to become a Hellspawn as have so many men, and women, since before
he was created. All he has to do is teach the Spawn how to use their powers and
goad them into succumbing to the dark evil in their dead bodies... and do it without
telling them directly, the better to add to their confusion. But who will instruct the
Violator, to end his own confusion? His methods are base, mean and cruel. And
wrong. He has yet to come close to his master's expectations, always foiling the
best laid plans. But he has to prove himself, must prove to the Malebolgia that he is
better than mere humans, a better choice to be a Spawn. One day, he tells himself
often, he'll get up the courage to tell "the boss" what he feels. One day real soon.
He's been saying that for fifteen hundred years.
