Defilers are iconoclasts and a subtype of Vandals who stain, vandalize and/or destroy sites or areas considered "sacred" in religious, political, cultural or Symbolic ways. This type of villain acts to desecrate targets and make it unworthy of any meaning, attacking a very symbol or value through its representation and is in some ways similar to sacrilege.

Defilers attack values they consider heretical, sinful, insulting, vituperative or responsible for their woes with the intent of taking it down thus relating to Fanatics, Anarchists or protesters and rioters, but their actions are always exceedingly disrespectful and sacrilegious, otherwise downright destructive and cruel.

Examples include people such as Revolutionaries who paint in graveyards or on buildings, ruin places of worship, destroy flags and so on and so forth.

Graverobbers, Necromancers and Death Gods relate to this in that they defile the right to "rest in peace" after passing on; in most cases this may even disturb the slumber of Souls or Spirits.
