Looking at the UFC's champions at the beginning and end of the decade (2010-2019)

Flyweight: Henry Cejudo

Henry Cejudo now holds Flyweight and Bantamweight gold

At the start of the decade, the Flyweight division didn’t even exist in the WEC, a promotion almost entirely focused around lighter weight classes. It was late 2011 when the idea of introducing a 125 lbs division was mooted, and eventually it became a reality in 2012.

Former Bantamweight title challenger Demetrious Johnson won the inaugural title fight, beating Joseph Benavidez to become the UFC’s first Flyweight champion, and he would hold the title for 6 years, making a UFC record of 11 successful defenses before losing to Henry Cejudo in 2018.

Cejudo thus far has made one defense of his title – a quick knockout of then-Bantamweight champion TJ Dillashaw – and going into 2020, question marks surround his reign, as he has since claimed the Bantamweight title too, and seems more focused on that division going forward.

Women’s Featherweight: Amanda Nunes

The Women’s Featherweight division in the UFC was essentially created for one fighter, Cristiane ‘Cyborg’ Justino. Although she didn’t fight in the inaugural title fight – that honour instead went to Holly Holm and Germaine De Randamie – she soon claimed the title by defeating Tonya Evinger in 2017 following De Randamie’s vacating of the belt.

‘Cyborg’ made 2 successful title defences before being upset by reigning Women’s Bantamweight champion Amanda Nunes in late 2018, and since then the title has been on ice as Nunes has instead defended her 135lbs crown. Going into the new decade, the future for the UFC’s thinnest division is somewhat up in the air.
