WATCH: MMA Legend Demetrious Johnson gains poetic justice with flying knee KO of Adriano Moraes

The trilogy of fights between Demetrious Johnson and Adriano Moraes will go down in history as some of the most high-level MMA contests we have ever seen in the sport.

Among them, their second fight stands out as the absolute peak of their rivalry as Johnson targeted revenge and the flyweight world championship.

Their first meeting at ONE on TNT 1 saw jaws hit the floor all around the world as Moraes became the first man to knock 'Mighty Mouse' out.

After a year and a half, the rematch was set for ONE on Prime Video 1 in August 2022, where Johnson didn't just even the score, he did it with his own highlight reel knee finish.

Four incredibly competitive rounds came to a sudden halt after Johnson hurt the champion with a right hand and timed a perfect flying knee to land the walk-off knockout, adding another incredible highlight to his legendary career in the process.

Demetrious Johnson added to his legacy with this fight

ONE flyweight MMA world champion Demetrious Johnson was already considered to be one of the all-time greats before this fight.

However, great champions are often defined by how they respond to adversity, and we saw this play out in front of our very eyes.

Demetrious Johnson's confidence had taken a bit of a hit after that knockout loss to Moraes in their first meeting and the second fight was another contest that was pushing him to the limit.

'Mighty Mouse' stuck to his plan, stayed sharp, and when the opportunity came, he switched off the lights to secure the best knockout of his entire career.

Moraes pushed him to be better than before, and for that, both men will always be in debt to one another following their historic trilogy.
