#2. Henry Cejudo - former UFC flyweight champion
While Henry Cejudo has been in the news recently in the UFC for his interest in pursuing a fight at featherweight, his contributions to the flyweight division should not be overlooked. In fact, if Cejudo had lost to T.J. Dillashaw in 2019, the flyweight division could easily have disappeared from the promotion for good.

Having won freestyle wrestling gold at the 2008 Olympics, Cejudo made his octagon debut at bantamweight. He then dropped down to 125 lbs. Cejudo's first attempt to win the gold from Demetrious Johnson was unsuccessful. However, he was able to win the rematch at UFC 227 to snatch away the title.
Cejudo's only title defense at flyweight was the division-saving win over Dillashaw. From there, he moved up to win a second championship at bantamweight and while he has since retired, it certainly seems like he is interested in one day returning to the octagon.
#1. Demetrious Johnson - former UFC flyweight champion
One only has to look at the number of successful title defenses Demetrious Johnson has had at flyweight to see why he is ranked number one. 'Mighty Mouse' defended the belt a record-breaking 11 consecutive times. Figueiredo holds second place in this regard with one win and one draw as champion.
Johnson was the inaugural champion at flyweight and held the belt from 2012 to 2018 when he lost the gold via split decision to Henry Cejudo. That was the last time he competed inside the octagon as Johnson was traded to ONE championship. Since that loss, he has gone 3-1 during his spell with the Asian promotion.
Johnson has secured a vice grip on flyweight GOAT status and it will be incredibly tough to knock him off the top spot. He has set the benchmark and it is now up to future flyweights to see if they can surpass his unbelievably high standards.
