With spear/sword, pillow fists don't matter. Who'd be the ultimate gladiator?

Redefine that whole concept of hammerfists on a grounded opponent.

In all seriousness, Ngannou with a sledge hammer (since he knows how to use it effectively) would be terrifying. He'd probably be able to swing it for quite some time with the proper leverage without fatiguing too much.

Paul Craig, he looks like one of those old Saxon guys with a spear

I don't know anything about Paul Craig's family.
"Craig" is one of those old Pictish Scottish names. The Angles and the Saxons are Germanic in Origin.

Depending on the era, you'd more likely see him covered head to toe in blue tattoos, with an axe, sword, and a small shield.
There's also a high likelihood that he'd be completely naked; or possibly wearing some sort of kilt.

That said, I'd considering the fact that the Romans built a wall to keep those psychos out of what was later to become England, I'd be somewhat surprised (and I'm completely ignorant when it comes to Gladiators so give me some rope here) to see a Pict in the colosseum.

Conor McGregor with a sword and that agile panther like movement would be an absolute menace

He defeated an entire bus of fighters with a dolly. Imagine if he had an actual weapon.

Probably Arlovski, he looks like one of the guys from 300.
