Fists of Fury: Champion of Champions - The Witcher 3

The inhabitants of Skellige are very open and tolerant and prize physical strength and warrior bravado above all else. Geralt was thus not unduly shocked to learn the Champion of Champions was, in fact, a troll. A she-troll, to be precise.

The she-troll fell to Geralt's fists, earning him the title of the best fistfighter to be found. To this day his name is uttered with the utmost respect in the taverns of Skellige, the shady inns of Novigrad and the barnyards of Velen.

Geralt had already won a great many victories while fistfighting opponents across the land, but still could not call himself the best of the best. The champion of champions remained undefeated, waiting for Geralt to challenge him for his title.
