It is much less common in MMA for fighters to accrue tremendous winning streaks than it is in boxing.
That is what makes these unbeaten streaks all the more impressive.
With there being so many different styles and ways to end fights, even top fighters usually do not go on winning streaks of more than four or five in a row.
The mental toughness is takes to keep an edge over a perpetual conveyor belt of masters of different styles is mind boggling.
Just when a fighter thinks he can beat anyone in the world is when his next opponent usually finds a way to win.
Some fighters "pad" their records with mediocre fighters ("cans"), but keeping a streak alive is still a monumental task when competing against professionals.
Out of all the streaks, these are the most impressive in history.
Qualifications: Must be at least 10 victories in the streak, and since this is for "unbeaten" streaks, only an official loss ends a streak.
