A Provoker is a hero that wronged a villain - usually the Big Bad or the Heavy - so badly through his or her own actions that they were pushed beyond their sanity or near this point, creating a Nemesis. Provokers are also the opposite of heroic nemesis, although many heroes are both.

They are different way to declare a hero as a provoker:

• The provoker had severely injured, disabled or crippled its nemesis, or did the same (or even killed) their nemesis' lover/loved one's (if they had - since some villains do not approve love at all), right-hand or anyone that they care about. Example: Beowulf, making a nemesis out of Grendel's Mother after he killed her son or Dorothy Gale making a nemesis out of the Wicked Witch of the West after her house fell on her sister and killed her.
• The provoker stole or destroyed any object, usually a weapon or an artifact, that the villain was very attached to, or attempted several times to do so. Example: Gandalf making a nemesis out of Sauron for trying to claim the One-Ring.
• The provoker has personally made its nemesis either imprisoned or outcasted. Example: Shifu making a nemesis out of Tai Lung by imprisoning him during twenty years.
• The provoker had broke down psychologically their nemesis, either by mockery or scorn, or steadily made fun of the latter's failures. Example: George Beard and Harold Hutchins making a nemesis out of Tippy TInkletrousers by making fun of his name.
• The provoker always interfered in its nemesis' affairs. Example: Sherlock Holmes making a nemesis out of Professor James Moriarty for foiling half of his plans.
• The provoker had cursed its nemesis.

Some heroes might make a Nemesis completely unintentionally. One of the best instance could be Spongebob, who through his perpetual failures, makes a nemesis out of Mrs. Puff.

For obvious reasons, some may qualify as Pure Good so long as they don't go out of their way antagonize others in a more unnecessary and/or arrogant way. Many have qualified due to still showcasing almost exclusively positive traits, and are only provokers due to the fact their actions and opposition have affected their nemesis in a negative and/or inconvenient way.
