I wonder whether this spiky gentleman might be a " jetthy" (not sure whether I spell it right): bodybuilding guards of the Indian rajas ( Tipoo had quite a lot) who doubled as executioners. The methods they used were designed to demonstrate their physical strength but were rateher gruesome: twisting the head off, hammering a large nail into the head with their one blow of a bare palm, crushing the chest with one blow of the fist or with a hug, tearing the limbs off etc, etc....
Arms and armour were used just as a fashion statement ( where is D2K when one needs it?

)
