#2. Israel Adesanya

Israel Adesanya has become one of the most marketable UFC fighters largely due to his kick-boxing style. His ability to end the fight with a single strike has led to must-watch moments that attract plenty of fans.
On top of this, Adesanya is incredibly charismatic. His interviews are consistently entertaining and his ring-walks are full of showmanship. His social media channels are also very popular even if he does get himself into frequent online trouble.

Comedy aside, 'The Last Stylebender' blazed the ranks to become UFC champion and he still makes top challengers look ordinary.
Parlaying his UFC dominance, Adesanya has attracted big sponsors including athletic apparel and footwear company Puma. He also recently launched his own energy drink, partnering with Kill Cliff to create their new 'Tekilla Kiwi' flavor.
Should Adesanya maintain this combination of strong UFC performances and high levels of entertainment outside of it, who knows how big a star he may become.
#1. Francis Ngannou

You only need to take one look at Francis Ngannou to understand he is a star. The heavyweight champion's ridiculous physique would likely be enough in itself to get plenty of attention if he weren't also the most dangerous man on the planet.
Ngannou has been faultless in his recent UFC fights and his terrifying knockout victories have made a lot of headlines. On top of this he is incredibly well-spoken and his rags-to-riches story is hollywood movie ready.
While some may not flock to his relaxed attitude, his ability to stay out of trouble is very attractive to brands looking to work with him. While other UFC fighters have found success with outlandish antics, there is certainly something to be said for only being in the news for positive reasons.
Ngannou sports a variety of endorsements and even featured as a villain in the recent Fast and Furious 9 film. Big moves like this indicate he is right on the verge of true mainstream stardom -like Conor McGregor.
Ngannou has the chance to become an even bigger star in his upcoming UFC title unification fight against Cyril Gane. If he wins, he could be set for a long and lucrative reign at the top of the division.
