The 10 Most Complete Fighters in MMA: No Holes in Their Game

The most dangerous fighters are the ones with no obvious way to beat them. We averaged every attribute in our engine — striking, grappling, defense, durability and fight IQ — to surface the fighters with the fewest weaknesses. These are the ten most complete mixed martial artists in the sport: the ones who can win the fight wherever it goes.

What "complete" is being measured against

Complete does not mean good at everything equally. It means having no phase an opponent can force the fight into and win. A striker with a takedown defence hole is not complete however good the striking is, because every opponent now has the same game plan.

The data shows the profile clearly. Islam Makhachev averages 3.22 takedowns per fifteen minutes while defending 91% of those attempted on him — both directions at an elite level — and absorbs only 1.42 significant strikes per minute. That combination, rather than any single number, is what completeness looks like when it is counted.

The test that matters

A useful way to judge it: name the game plan you would give an opponent. For most elite fighters there is an obvious answer — take him down, keep it standing, drag him late. For the genuinely complete ones the honest answer is that there is no plan that does not also expose you to something worse. That is a harder bar than any statistic.

Who just missed

Alexander Volkanovski — arguably belongs; kept off only by the recent losses at the very top. Belal Muhammad — no exploitable phase, and rarely credited for it. Sean Brady — 3.58 takedowns landed, 86% defended, and competent everywhere else.

Why completeness beats specialisation over a career

A specialist has a higher ceiling in the fights that suit them and a floor that falls out in the fights that do not. Across twenty fights against varied styles, the complete fighter wins more even where the specialist would win the head-to-head. That is also true in our career mode, where spiking two attributes and neglecting the rest produces a spectacular run that ends the first time the matchmaker finds the hole — which is the single most common way a promising career run comes apart.

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.
