This Saturday (2), former GLORY Kickboxing champion Alex Poatan enters action at UFC 276 with an eye on a fight for the organization's belt.
Remember other elite kickboxers who shine or shine (some more than others) in MMA.
Current UFC middleweight champion, Israel Adesanya had a respectable career in kickboxing, even winning a GLORY tournament.
In total, there were 75 victories and only five defeats, two of them against Alex Poatan.
It's impossible to talk about kickboxing and MMA and not think about Mirko Cro Cop. Known for his lethal left leg, the Croatian was champion of tournaments in PRIDE (MMA) and GLORY (Kickboxing).
A disciple of the traditional Dutch school, Alistair Overeem was champion of a Glory tournament, knocking out the legend Peter Aerts.
In MMA, he was Strikeforce and DREAM champion and spent years being one of the UFC's top heavyweights.
Germaine de Randamie is one of the greatest kickboxers in history. Undefeated in the sport, the Dutchwoman has 46 victories, 30 of which were by knockout.
In MMA, Germaine was the first UFC featherweight champion, but later lost the belt for refusing to defend the title against Cris Cyborg.
Mark Hunt retired from MMA with a negative record, it's true. Still, the "Super Samoan" had notable victories and challenged for belts in PRIDE and UFC (interim).
In kickboxing, Hunt won a GP title in K-1 in 2001 and retired with a record of 30 wins and 13 losses.
Semmy Schilt is a kickboxing legend, with world titles at Glory and K-1, where he was also multiple tournament champion.
In MMA, the Dutchman was not as successful. Despite retiring with a record of 26 wins and 14 losses, he did not do well when facing renowned opponents such as Minotauro, Fedor and Barnett.
One of the UFC's most dominant champions, Valentina Shevchenko made history in kickboxing and Muay Thai before shining in the Octagon.
Between the two sports, there were eight world titles, 57 victories and only two defeats.
Michael Page is another athlete who comes from kickboxing. The "MVP" began competing as a child and accumulated ten world titles in points kickboxing.
In MMA, the Bellator fighter has 20 wins and two losses, the last of which came in a title fight.
