Bully characters in fiction often seem to use very similar tactics with similar motivations. Beyond just beating up or tormenting their victim, they like humiliating them more than anything- and what a better way than to publicly beat them at a challenge or watch them back down as a coward?
As such, this plot occurs when a bully and their victim- who is often the protagonist- face off in a challenge. Sometimes it's a traditional fight, which often results in the victim getting a Boxing Lesson. Other times it's an actual contest in a field the bully believes the protagonist will have no talent in. Sometimes someone will set up the challenge for the protagonist in the assumption that they'll win, or the protagonist themselves will make the declaration, but there must be an actual challenge offered for this trope to occur. If the protagonist is the one to make the declaration, they're usually fighting for someone other than themselves. Or, the bully themselves will challenge the protagonist.
These challenges are almost always public (even if it wasn't meant to be, a la Spontaneous Crowd Formation). They can occur as the climax of the story, but it's not a requirement, as they can also happen at any other point.
Results may vary. In most cases the protagonist wins, either thanks to their hard work preparing and the bully's overconfidence, the Beware the Nice Ones factor, or because the bully was Bullying a Dragon. In some cases, this will lead to Defeat Means Friendship in works that avert Status Quo Is God. However, it most often doesn't lead to anything, and the bully will remain their usual selves come next episode. Sometimes, however, the bully ends up the victor regardless, often with a Curb-Stomp Battle.
Please note that for an example to fit this trope a challenge of some form must be present or implicit. A character standing up to their bully without a challenge being made is not this trope.
- Doraemon: In one chapter, Doraemon has to go back to the 22nd century because his duty has been "fulfilled" (i.e making Nobita happy), but he's reluctant because he comes to care about Nobita too much. Nobita tries to prove that he doesn't need Doraemon anymore, one of the methods being challenging the local bully, Giant. While Nobita is badly beaten, he keeps coming after Giant, who ended up getting scared of him because he just won't back down. This at least convices Doraemon to go back "home".
- In Yu-Gi-Oh!, this is the M.O. of Yugi Muto — or, more accurately, his Superpowered Evil Side. Because of Yami Yugi's shadow magic, this typically ends with the bully coming down with a bad case of Mind Rape. This also happens in the anime, but with more card games and less mental punishment for Yugi's opponents.
- In an early issue, while Peter was still in high school, he gets forced by a teacher to challenge his bully, Flash Thompson, to a boxing match. This, of course, puts Peter in the situation of how to resolve things without giving away that he's Spider-Man. Eventually, he just pops Flash in the jaw hard enough to leave Flash dazed and unable to keep fighting, and tells the crowd that obviously Flash is throwing the fight, since wimpy Peter Parker couldn't possibly hit hard enough to knock him out in one blow. The crowd is quick to jump on this as evidence that Flash must be Spider-Man, throwing the fight so as to avoid revealing his superpowers.
- Subverted in one of the earliest issues. Peter has enough of Flash's bullying, and grabs him to start a fight. Then he remembers that he has superpowers, and may seriously harm or even kill Flash if they fight (and reveal his identity), so he let him go.
- The fight was reimagined in the first arc of Ultimate Spider-Man. Peter orders Flash to stay away from Mary Jane, and this led to an after school fight, but Peter simply tries to elude his attacks. At one point, he manages to stop one of his punches with his hand, and that broke Flash's hand. He spent many later issues with the hand bandaged, and had to be removed from the basketball team.
- Ultimate Daredevil & Elektra: When Elektra saw Trey abusing of a female student with his gang, he forced him to return her her folder. First she told him, then he took him down and humilliate him.
- In one Peanuts strip, Linus complains about always having to watch whatever Lucy wants to watch on tv. Lucy then threatens to slug him, but instead of backing down, or taking the hit like usual, Linus just walks over to the tv, changes the channel, and then looks Lucy directly in the eye and says, "You don't frighten me one bit." Linus gets to watch his show while Lucy just stands there and cries.
- In My Huntsman Academia, Izuku stands up to Cardin Winchester during his eighth week at Beacon, challenging him to a fight in sparring class in front of everyone else. Cardin, being the Smug Snake he is, agrees. But Izuku has been actively grinding as many levels of badass as he could since they met in his first few weeks at Beacon, including developing One For All: Full Cowl. Cardin's complacency proves to be his undoing when Izuku utterly curb-stomps him without taking any damage, destroying Cardin's reputation and forcing him to stop bullying others.
- A Christmas Story: Ralphie ends up challenging (and thrashing!) the local bully Farkus after Farkus hits him in the face with snowball. Ralphie was already having a bad day, and this was the final straw.
- Sky High (2005): Thanks to his newfound powers, Will's friends decide he'd be able to defeat the two bullies, Speed and Lash, in a game of Save The Citizen. Though he spends the conversation insisting he has no interest in competing with them, the challenge is made anyway, with the stakes being a year without bullying or his friend's head being dunked in the toilet every day.
- Three O'Clock High: Double subverted. Most of the film's plot follows Jerry Mitchell's increasingly insane attempts to escape the fight challenge that school bully Buddy Rydell has given him, but on the third act Buddy pisses Jerry off by calling him a coward and thus Jerry accepts Buddy's challenge for real.
- Skippy Dies combines this with Cock Fight. Skippy and Carl are both rivals for Lori's affection, but Skippy is a quiet nerd who is frequently bullied, while Carl is a psycho who bullies younger kids and sometimes pushes Skippy around. After being repeatedly threatened, Skippy challenges Carl to a fight. Surprisingly, Skippy is able to land a punch on Carl and "win" the fight, by visualizing attacks from his favorite video game.
- Harry Potter and the Philosopher's Stone:
- Draco Malfoy challenges Harry to a duel at night in, but this is a Subverted Trope because Draco doesn't actually show up and just wanted to get Harry into trouble.
- Malfoy steals a Rembrall from Neville, a frequent target of his bullying, and mocks him for injuring himself. Harry gets tired of this and rises on his broomstick, challenging Malfoy to a contest of flying skills. Harry is able to retrieve the Rembrall through a tricky broomstick maneuver, defending Neville's honor and coming out on top.
- In Song of the Lioness Ralon is a petty bully, constantly picking on main character Alanna secure in the knowledge that she (though he thinks she's a boy) can't report him without losing honor. So, for the next few months she spends her nights training in hand-to-hand combat and then challenges him in the practice yard in front of everyone. And totally kicks his ass.

Though he and everyone else believes he'll fail, Dirga teaches him the proper technique to lifting weights, and he ends up defeating Loomer in front of the entire school.
- In "After School Special", the season 4 episode of Supernatural, we see in a flashback that, in a desire to blend in and be normal, Sam will ignore bullies that pick on him personally, but woe to anyone who picks on people Sam considers to be a friend or under his protection. When bully Dirk decides to beat up Sam's new friend Barry, even kicking him when he's already down. Sam tells Dirk to leave Barry alone, but Dirk cockily challenges the diminutive Sam to a fight. Sam proceeds to lay a curb stomp beatdown on the bully, despite Dirk being easily twice Sam's size. He also crowns the bully Dirk the Jerk, a nickname that would follow the bully the rest of the way through school.
- The premise of the Ninja Sex Party song "Cool Patrol" is Danny Sexbang teaching a high school boy getting picked on how to deal with bullies. The training consists of learning a silly dance, but gives the kid enough confidence to approach the bullies with an implicit challenge... before he's promptly beaten up and possibly killed.
- Given that wrestling is, in and of itself, a fighting contest, and many Heels are bullies, this is one of the most common storylines.
- In All Japan Women's Pro-Wrestling, the feud between the Crush Gals (Lioness Asuka and Chigusa Nagayo) and Dump Matsumoto's Atrocious Alliance in the mid-80s is a famous example. The Atrocious Alliance ran rampant through AJW, and the Crush Gals were the underdog Faces standing up to them. The heat generated from the audience was comparable to what Hulk Hogan was getting at the same time in the US.
- In WWE NXT, Shayna Baszler exploited this by bullying other wrestlers to get champ Ember Moon to put her title on the line against her.

- Phineas and Ferb: "Raging Bully" introduces the character of Buford, who is shown as a stereotypical bully when he challenges Phineas to a fight after the latter spills ice-cream on him. The fight turns out to be a thumb war treated like a boxing match, and Buford almost wins until Phineas gets icecream on his own shirt thanks to Perry and Doofenshmirtz. Buford calls off the fight, seeing as he and Phineas are even, and they become friends.
- The Simpsons episode "Bart the General" has Bart defending Lisa from school bully Nelson Muntz (making his debut), and gets beat up for his efforts. This leads to a final confrontation between the two, which becomes a pastiche of WWII movies.
- South Park: In "Breast Cancer Show Ever", Wendy Testaburger, after getting fed up with Eric Cartman mocking breast cancer, challenges him to a fight after school.

Cue a devastating No-Holds-Barred Beatdown from Wendy that leaves Cartman lying in a pool of his own blood.
- In the Tiny Toon Adventures episode, "Hero Hamton", Hamton accidentally hits Montana Max with his locker door. When he tries to apologize, Monty threatens to beat him up, and Plucky makes the situation worse by telling Monty that Hamton could easily beat him in a fight.
