Provokers are heroes that wronged a villain - usually the Big Bad or the Heavy - so badly 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 to antagonize others in an 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.
