5 biggest UFC babyfaces and their biggest heel moments

#4 Jose Aldo

Aldo has gone full heel in the last year or so

Jose Aldo was one of the most respected fighters in the world for many years.

He was the UFC Featherweight Champion and was undefeated for over a decade back in 2015, it even looked as if he would go on to be known as one of the greatest champions in the history of the sport.

Unfortunately, that's where Conor McGregor stepped in and turned his world upside down.

Aldo's heel turn was more forced upon him than anything else, as he seemed to completely lose his morals following the 13-second knockout at the hands of the Irishman. Aldo was complaining left right and centre about both Conor and the UFC as a company, threatening to walk out and even refused to fight on a number of occasions.

Then, he was unfairly promoted to the position of Undisputed Champion once again. That's not particularly professional, Jose.

We conclude with the most tragic story of all.
