And whats to stop Riddick from using something other than his fists to KO Marv? Think about the sledgehammer Kevin used on Marv, Riddick could easily twirl that around like a baton. No doubt Riddick will have difficulty KOing Marv with his hands, thats why he would pick up something from the alley and use it. And, as I said, all Riddick would need is a small piece of glass to open up Marv's jugular. With a blade, or anything that cuts, Riddick is a damn surgeon.
You are underestimatimg Riddicks strength, In the battle towards the end, on Crematoria, Riddick displays feats of strength that match/surpass what Marv has to offer.

[edit] Physical abilities
Aside from his more supernatural skills, Riddick is in excellent physical condition and is an exceptional fighter with or without the use of his eyes. Whether as a result of his Furyan heritage or simple training, Riddick is portrayed in both films as being stronger, faster, tougher, more resistant to damage and injury, possessing more acute senses, immense stamina, and recovering more quickly than most humans from injuries; he is shown on more than one occasion dislocating his limbs for brief moments with only slight signs of discomfort. In general, Riddick possesses an abnormally high pain threshold and psychologically channels what pain he does feel into anger.
Riddick's abilities at hand-to-hand combat are particularly formidable, confronting one of the night-creatures of Pitch Black with only his bare hands and a shiv he had made, breaking its neck, as well as defeating one of the Lord Marshall's best Necromonger warriors in a matter of seconds in Chronicles.
[edit] Intelligence
Despite his harsh upbringing and violent streak, Riddick has been shown to have a certain deductive streak, rapidly concluding what had happened to the original inhabitants of the mining base where he and the other crash survivors had been staying, as well as finding the creature's blind spot in Pitch Black and swiftly deducing what had caused the firefight between the wardens and Toombs' men in Chronicles. He has also been described as having "a knack for escape", surviving not only the Lord Marshall's purge of the Furyans when he was an infant but subsequently escaping from various prisons over the course of his life. He is also able to quickly judge the quality of, and find even seemingly minor flaws in most weaponry, down to very specific details. In one case, Riddick concluded that the prized dagger of a Necromonger was "half a gram too heavy on the back end" after an inspection lasting all of a couple seconds. His only weakness (other than light sensitivity), as stated in the Pitch Black DVD, is his soft spot for children and anyone who really grows on him (those people become his friends), which resulted in his capture by the bounty hunter Johns (Cole Hauser).
In addition to raw analytical power, Riddick is generally an astute judge of character, especially in the dark side of human nature. A killer himself and resident of almost one hundred maximum security facilities, he is often able to predict an individual's negative impulses before they act on them. He has been known to be surprised on occasion, such as when Carolyn Fry in Pitch Black altruistically gave up a fast escape to save Jack (Kyra) and Imam from the alien creatures, and underestimated Jack's (Kyra's) affection toward him between Pitch Black and The Chronicles of Riddick, only learning of it after she had become a mercenary and resident of a maximum security slam. Otherwise, he correctly predicted which of the group in Pitch Black would turn on each other (in particular that Johns would try to double-cross Fry), and that the mercs and guards on Crematoria would turn on each other prior to his escape attempt.
[edit] Willpower
One major characteristic of Riddick is his indomitable will. Despite finding himself in situations where the odds of survival and/or escape would seem insurmountable, Riddick always pushes forward and never gives up. Faced with several creatures far more powerful than himself, or any other human for that matter, he has shown himself to be capable of evading, killing, or even taming them. He has escaped out of prisons when most prisoners would resign themselves to captivity. When Riddick was mentally probed by the Quasi-Dead of the Necromongers, he not only resisted them, but also retaliated. Given the Necromongers' apparent faith in and respect for the power of the Quasi-Dead, this is a very impressive feat. Perhaps even greater was his ability to resist the Lord Marshall's attempt to steal his soul.
So yeah, Riddick is superior to Marv in every possible way.
