Heroes who sometimes act as heroes and sometimes don't. Some of these heroes aren't villains and just act rather neutral while others have a villainous side, and some of them fall under the category On & Off on Villains Fanon Wiki.

Note: None of these characters are Pure of Heart nor Near Pure Good as there are never any breaks in a Pure of Heart or Near Pure Good's heroism, and doing good for them is just as natural as breathing, unlike an On & Off hero.
