#5 Jose Aldo
When the UFC bought out WEC, Jose Aldo had already been the featherweight Champion for almost two years and had defended the belt twice. When the defunct promotions’ fighters and weight categories were absorbed by Zuffa, the UFC made Aldo its 145lbs champion – a title he wouldn’t lose for the best part of five years.

Throughout his reign as the featherweight champion, Aldo became known for his vicious leg-kicks and he used his Muay Thai-based style and remarkable takedown defence to keep the belt firmly strapped around his waist for while he strung together an 18-fight, 10-year unbeaten run. Arguably his greatest performances came against Chad Mendes and Frankie Edgar, both of whom he defeated twice.
The Brazilian’s reign came crashing down in 2015 when he lost the belt to Conor McGregor in just 13 seconds. However, even before that contest ‘Scarface’ had already etched his name into the history books as one of the most dominant champions ever to grace the UFC’s Octagon.
