Consecutive UFC Wins: 6
There are currently five fighters with six straight UFC victories. That includes UFC champions Aldo and Demetrious Johnson as well as some elite contenders in the 135- through 155-pound weight classes.
Had WEC wins been included for purposes of these rankings, Aldo would be much higher up the list. However, injuries have prevented the featherweight champion from competing more than twice in a year since he joined the UFC roster.
Still, Aldo has defended his belt numerous times, beating Mark Hominick, Kenny Florian, Mendes, Frankie Edgar, Chan Sung Jung and Ricardo Lamas. The 145-pound king will look to pick up a second win over Mendes next month.
Since the UFC flyweight division was created, Johnson has not been beaten.
Mighty Mouse fought to a draw with Ian McCall in his debut at 125 pounds, but he's won all six fights since then. Those victories came against McCall, Joseph Benavidez twice, John Dodson, John Moraga and Ali Bagautinov.
On September 27, Johnson will look to extend his winning streak in a favorable matchup with Cariaso, who many feel is not ready for a shot at the champion.
Undefeated in six UFC appearances, Khabib Nurmagomedov looks like he has the potential to become a future lightweight champion.
With his outstanding wrestling, Nurmagomedov has had little trouble running through his UFC opposition. Rafael dos Anjos, Pat Healy, Abel Trujillo, Thiago Tavares, Gleison Tibau and Kamal Shalorus have all fallen against the Russian.
Since losing to Ricardo Lamas in his UFC debut, Cub Swanson has done nothing but win.
While facing some stiff competition, he has recorded four knockouts in six straight victories. In beating Jeremy Stephens, Dennis Siver, Dustin Poirier, Charles Oliveira, Ross Pearson and George Roop, Swanson has separated himself as one of the top contenders in the featherweight division.
Having defeated current bantamweight champion T.J. Dillashaw during his current run, it's surprising that Raphael Assuncao isn't lined up to fight for the belt. Instead, the Brazilian is preparing to fight Caraway on October 4 in a bout that could finally earn him a shot at UFC gold.
After losing to Erik Koch at 145 pounds in his UFC debut, Assuncao opted to drop down to 135 pounds, a decision that has seriously elevated his career. Beating Johnny Eduardo, Issei Tamura, Mike Easton, Vaughan Lee, Dillashaw and Pedro Munhoz, Assuncao has not lost in the bantamweight class.
