Mixed Martial Arts is fundamentally defined by its first word. The sport of MMA was built upon, and features athletes of mixed styles from many different disciplines of martial arts. This mixture has created a phenomenon in competition. MMA started off pitting two different styles against one another, but has now evolved into producing well-rounded fighters who study in many disciplines.
The game has changed, and athletes have adapted themselves in order to compete in the ever-changing sport. New competitors have come in, already training in many martial arts. The sport is truly MIXED with many fighters knowing many disciplines.
Still, there are those who stand out in a particular field. While being substantial at other styles, these fighters truly excel at one, and have had success using their foundational style.
This slideshow contains just eight of many styles, but these styles are very prevalent in MMA. These are all UFC fighters that are at the top of the heap in their respective discipline. This is not a conclusive list of all who are notable, but those who are both popular and who are arguably the best at their craft.
