1. Demetrious Johnson
Now fighting for ONE Championship, Johnson was the first UFC flyweight champion. Nobody could touch him at 125 lbs as he went on a ridiculous run of defenses, running up a UFC record of 11 title wins. Johnson is a complete fighter with excellent striking, creative grappling and BJJ, as well as ludicrous athleticism. If you’ve seen his flying armbar win over Ray Borg, you’ll know what we’re talking about.
Some will point to his lack of a standout opponent as a reason why he shouldn’t top this list. However, equally, you could say that he was just so good that nobody was able to really test him. Even Henry Cejudo, who eventually defeated him in 2018, lost against Johnson the first time they fought. Furthermore, many people believed that D.J did enough to win in their rematch. Ultimately, “Mighty Mouse’s” record speaks for itself.
