Two division champion Amanda Nunes is one of the most dominant UFC champions of all time and Julianna Pena got the title fight being just about the only one left to beat.

The Brazilian had dominated two whole divisions and was attempting her sixth bantamweight title defense while Pena was a 7-to-1 underdog going into the fight

However, Nunes lack of motivation and Pena’s determination and stiff jab still led to the second biggest UFC upset of all time.
