The 10 Most Complete Fighters in MMA: No Holes in Their Game
Ranking · June 14, 2026 · MMAFightSim
1
Jon Jones · Light Heavyweight
Overall: S+ (our engine)
The blueprint for a complete fighter: long-range striking, elite wrestling, a grappler’s submission game and a fight IQ that always seemed two steps ahead. He retired undefeated as heavyweight champion in 2025.
2
Demetrious Johnson · Flyweight
Overall: S (our engine)
Often called the most technically complete fighter ever. “Mighty Mouse” could out-strike strikers and out-grapple grapplers, with a record 11 straight title defenses to prove it.
3
Islam Makhachev · Welterweight
Overall: S (our engine)
Elite grappling built on Khabib’s foundation, plus sharp, still-improving striking. He became a two-division champion at UFC 322 and is riding a sixteen-fight win streak.
4
Kayla Harrison · Women's Bantamweight
Overall: S (our engine)
Olympic-level judo, fast-developing striking and championship poise — a combination that made her women’s bantamweight champion in just her third UFC fight.
5
Valentina Shevchenko · Women's Flyweight
Overall: S (our engine)
“Bullet” is a precision Muay Thai and kickboxing technician who also defends takedowns and grapples at a championship level — the most complete fighter in women’s MMA.
6
Georges St Pierre · Welterweight
Overall: S (our engine)
The original complete welterweight: record-setting wrestling, crisp boxing and the discipline to impose whichever game won the night. He retired as a two-division champion.
7
Leon Edwards · Welterweight
Overall: S (our engine)
A patient, well-rounded welterweight with slick kickboxing, underrated grappling and the composure that produced his last-minute head-kick knockout of Kamaru Usman.
8
Umar Nurmagomedov · Bantamweight
Overall: S (our engine)
Another product of the Dagestani grappling dynasty, with the family wrestling base plus the sharpest striking of the bunch — a genuine two-way threat at bantamweight.
9
Ilia Topuria · Lightweight
Overall: S (our engine)
A rare fighter who is truly elite both standing, with real knockout power, and on the mat as a black-belt grappler — which is exactly what makes “El Matador” so hard to solve.
10
Tom Aspinall · Heavyweight
Overall: S (our engine)
A heavyweight with rare speed, one-punch finishing power and legitimate submission skills. He was elevated to undisputed champion in 2025 after Jon Jones retired.
