1. 1

   

   Usman vs. Edwards II

   Leon Edwards in round 5

   2022 | UFC 278

   Maybe the best comeback of all time, this fight ends with a perfectly set up head kick after 5 rounds resulting in one of the greatest walk off KOs for a championship belt
   

2. 2

   

   Aldo vs. McGregor

   Conor McGregor in round 1

   2015 | UFC 194

   KOing one of the greatest of all times inside 13 seconds for the belt after the UFC threw him into a title fight where McGregor connects with a beautiful cross that lands flush on the Jaw.
   

3. 3

   

   Kasanganay vs. Buckley

   Joaquin Buckley in round 2

   2020 | UFC Fight Night

   One of my favorite KOs of all time, while this fight was not one of the magnitude KO's that the other fights have this one was one of the most creative and brutal KOs of all time.
   

4. 4

   

   Overeem vs. NGannou

   Francis NGannou in round 1

   2017 | UFC 218

   He KOd the guy like a freaking cartoon.
   

5. 5

   

   Henderson vs. Bisping

   Dan Henderson in round 2

   2009 | UFC 100

   Henderson gets upset by Michael Bisping cementing his moniker, Left Hand Larry, as he KOs Hendo with 1 eye for the Title!
   

6. 6

   

   Askren vs. Masvidal

   Jorge Masvidal in round 1

   2019 | UFC 239

   Fastest UFC KO kickstarting Masvidals resurgence a beautiful jumping knee catching Askren shooting a takedown. This addition to the list was "Super Necessary"
   

7. 7

   

   Rousey vs. Holm

   Holly Holm in round 2

   2015 | UFC 193

   Rousey was basically an unbeatable robot at the time and she was finishing everyone. But Holm showed off how quickly UFC women's division was progressing and how fast. Rousey would only fight 1 more time.
   

8. 8

   

   Machida vs. Belfort

   Lyoto Machida in round 2

   2018 | UFC 224

   When Machida hits the front kick on a juiced out Vitor Belfort as his last act in the UFC, he capped off a story of a phenom who was one of the most unique and best strikers of all time.
   

9. 9

   

   Jung vs. Rodriguez

   Yair Rodriguez in round 5

   2018 | UFC Fight Night 139

   This is what I figured they would do as a ROad House KO script scene. How Yair beautifully draws Zombie in before snapping his elbow up with 1 second left in the round to Zombie just crumpling to the mat, the confusion and then the replay showing such a crafty finish against one of the best fighters to never win gold in UFC history.
   

10. 10

    

    Emmett vs. Mitchell

    Josh Emmett in round 1

    2023 | UFC 296

    I mean this can move up the list as we get further away from the fight and context grows but by sheer violence of the KO Josh Emmett hitting Bryce Mitchell with an Ivan Drago level overhand sending Mitchell to the canvas shaking.
