Who is Spider-Man? He's a criminal, that's who he is! A vigilante! A public menace!
~ J. Jonah Jameson condemning Spider-Man as a villain (again)
Who gets stuck with all the bad luck? No one... (Donald quacks angrily) but Donald Duck! (Donald Duck: Yeah!)

Scapegoats are heroes who are being subjected to upsetting situations. These heroes are often wrongfully mistreated and accused of being evil or somehow in the wrong even though they are trying to act in a benevolent manner. Often times heroes are turned into scapegoats by a villain or antagonist so as to get them out of the way of their goals. However, these characters are submitted to other circumstances that can be harsh, unfair, or even downright cruel, and because of this it could cause them to become a villain. They can be:
The Butt Monkey: Heroes who are constantly on the receiving end of jokes, such as being awfully abused/humiliated in an unusual or slapstick manner, such as Daffy Duck, Tom the Cat or Scrat from the Ice Age film franchise.
The Love Martyr: Heroes who stay with their loved one in spite of their major personality flaws. A good example would be Mikiya Kokutou, who continues to stay with Shiki Ryougi even after she attempted to kill him, albeit with deep remorse on her part.
The Hurt Immortal: Characters who are killed and constantly revived just to be killed all over again such as Kenny McCormick, Rory Williams, and many Happy Tree Friends heroes.
The Hero with Bad Publicity: Heroes who are viewed with contempt by the public in spite of all the good deeds they do, usually due to someone smearing their reputation. Good examples include Harry Potter, Spider-Man and Mr. Incredible. Saitama and Shiroe count as well, except they smear their reputations on purpose.
The Rudolph: Heroes who are viewed with contempt or fear by everyone around them just for being different, such as Inuyasha and Shrek.
The Designated Victim: Heroes who are constantly targeted or kidnapped by the villains. Good examples include Princess Peach and Daphne Blake.
The Disaster Inventor: Scientists who create and use inventions to benefit themselves or others, but their creations usually backfire, causing unintended consequences: Dexter from Dexter's Laboratory and Jimmy Neutron are good examples of this.
The Woobie: Tragic heroes that from traumatic experiences that could cause them to fall in Despair Event Horizon as it caused the audience to feel pity for them: Asura had a horrible premonition about the death of his wife, Durga, and the kidnapping of his daughter, which led to his dark path for vengeance.
The Tykebomb: Heroes who were raised for combat from a very early age and so had no chance to live a normal life. Often, these heroes worked for villains before defecting to the good side. It usually takes another hero to bring out the good in them. Good examples include River Song, Shana and Sousuke Sagara.
The Unfavourite: Heroes who, for some completely unfair and often ridiculous reason, are regarded as a disgrace by their family, to the point that they might even get disowned by them. Peter Petrelli, Kazuma Yagami and Ikki Kurogane fit this perfectly.
The Orphan: Heroes who loses his/her parents at the hands of the main or minor antagonist, natural causes, tragic accidents etc. as a child. Example: Batman's parents Thomas and Martha Wayne were murdered at the hands of Joe Chill in "Crime Alley". And sometimes, when being orphaned is bad enough, the hero would be taken in by abusive guardians, rather than their assigned godparents. (Harry Potter's parents James and Lily were murdered by Voldemort, so he was left at the Dursley's house, where he was locked in the cupboard under the stairs and treated as nothing more than a servant. The reason was because Aunt Petunia shared the same blood with her witch sister Lily, and Sirius Black was in Azkaban prison for supposedly betraying the Potters and killing 12 muggles)
The Remorseful Git: Former jerks who wanted to apologize to their loved one(s) for getting angry with them, only for the latter to die before they could. Example: Homer Simpson refused to love his mother ever again because she has been faking her death too much to hide from the goverment. Feeling bad for what he has done, he goes downstairs to apologize, but she has already died.
