Troublemaker Hero

A troublemaker hero is a protagonist who is either mischievous, rebellious, or unruly. This type of hero may not believe in following rules declared by society, but still commits acts of heroism, albeit by following their own moral codes.

Why This Trope Is Not So Naughty

 * 1) Similar to tricksters, they seek opportunities to extend their curiosity about the world around them and gain new knowledge and wisdom in the process.
 * 2) *In fact, many fictional heroes and heroines are rule-breakers. This is not a coincidence, as many of them go into the unknown and explore. They take risks, not least the risk of social disapproval.
 * 3) This trope adds both comedy and badassery to the characters' personalities with their mischievousness, rebelliousness, inquisitiveness as well as hilarious schemes and shenanigans, with a fair amount of bravery.
 * 4) *Their antics can be entertaining to watch, as they are often the source of conflict, which is what the hero uses to drive the story.
 * 5) They reflect on the fact that we all make make mistakes. What matters is that we learn from them.  As a result, they teach the audience valuable lessons to take to heart.
 * 6) They inspire the audience to stand out, think for themselves, be independent, question the ways of society, take risks and have the courage to stand up for what they believe in, even when it is not expected of them.
 * 7) Like anti-heroes and idiot heroes, troublemaker heroes can be easy to relate to, as there are people who don't enjoy conforming to the norm or following rules outside of their own, so they identify with the protagonist's desire to live a life without doing what is expected of them.

The Only Bad Quality

 * 1) Sometimes, the troublemaker hero's antics can be annoying and unfunny.
