The boxer-puncher may also be more willing to fight in an aggressive swarmer-style than an out-boxer. The boxer-puncher possesses many of the qualities of the out-boxer: hand speed, often an outstanding jab combination, and/or counter-punching skills, better defense and accuracy than a slugger, while possessing slugger-type power. Sluggers often throw predictable punching patterns (single punches with obvious leads) which can leave them open for counterpunching. Compared to swarmers and out-boxers, sluggers normally throw fewer but harder shots and rely less on combinations. Most sluggers lack mobility in the ring and may have difficulty pursuing fighters who are fast on their feet but that is not always the case.

This is advantageous in punching through an opponent's guard and creating an opportunity to follow with further blows. Sluggers' punches are often slow but have more body and follow through. Many sluggers tend to lack finesse in the ring, but make up for it in raw power, often able to knock almost any opponent out with a single punch. If the out-boxer represents everything elegant about boxing, the slugger (brawler, puncher) embodies everything brutal about the sport. Since they rely on the weaker jabs and straights (as opposed to hooks and uppercuts), they tend to win by points decisions rather than by knockout, although some out-boxers can be aggressive and effective punchers. Out-boxers are known for being extremely quick on their feet, which often makes up for a lack of power. The out-boxer seeks to maintain a gap from their opponent and fight with faster, longer range punches. The out-boxer (out-fighter, boxer) is the opposite of the swarmer. Many swarmers are often either shorter fighters or fighters with shorter reaches, especially in the heavier classes, that have to get in close to be effective. They also tend to have a good ' chin' because this style usually involves being hit with many jabs before they can maneuver inside where they are more effective. They tend to be fast on their feet which can make them difficult to evade for a slower fighter or are great at cutting off the ring with precise footwork. This style favors closing inside an opponent, overwhelming them with intensity and flurries of hooks and uppercuts. Good power, a good chin, and a tremendous punch output (resulting in a great need for stamina and conditioning). Swarmers tend to have very good head movement in order to get inside. The swarmer (in-fighter, crowder, or pressure-fighter) is a fighter who attempts to overwhelm his opponent by applying constant pressure-taking away an opponent's usually superior reach. Many boxers do not always fit into these categories, and it is not uncommon for a fighter to change their style over a period of time. These are the swarmer, out-boxer, slugger, and boxer-puncher. There are four generally accepted boxing styles that are used to define fighters.
