Yeah... by juggling it with his feet and kicking it across the room. Even Batista is scared of that shit!
We're really using Batista as the yardstick for toughness?
If Zelda is such a powerful fighter, then why is it always up to Link to save the world? If Zelda is such a powerful telepath, then how'd she get managed to become possessed? If she can see the future, why is Hyrule constantly getting screwed over? Wouldn't she be able to devise a plan on how to prevent these evil plots that seem to happen over and over and over again?
Well because all the prophecies of the Hero of Hyrule state that Link has to be the one who saves the world. But there have been several instances where Zelda has done major damage to Ganon while fighting alongside Link. And I can promise you that Ganon is vastly more powerful than Riddick.
Though it's kind of a cop-out, Zelda has to abide by the prophecies of Hyrule. The time when a prophecy wasn't followed, Hyrule ended up underwater, flooded by the Gods because shit got so out of control.
She has to follow rules that limits the use of her powers and forces her reliance on Link. But no such rules apply in this tournament, so she can cut loose, something that is incredibly impressive in the rare times she's allowed.
Also, she got possessed by the darkness of the Twilight Realm. Something that would've turned Riddick's brain to mush had he been the victim.
Oh good, powers she's not aware of. I'm sure those powers she doesn't know how to use will be a huge help to her when she's not using them in this fight.
Jean Grey had powers she wasn't aware of. Then she became the Phoenix. You know how dangerous hidden powers can be when backed into a corner, or when given the freedom to let your powers out, the freedom that Zelda would be given in this tournament.
No no no, this is all wrong. Riddick is a GREAT fighter. Fighting is what he does. His culture is killing, and he's one of the best at it. What's Zelda good at? Getting kidnapped by a pig monster and bossing Link around.
When she's at her best, she's also very good at helping Link defeat Ganon. Again, that's someone way more powerful than Riddick could ever be.
Riddick slits Zelda's throat in a scene way to graphic to be shown in a Nintendo game.
Riddick kicks swords and bullets and whatever else he can find at Zelda, which does no damage due to Zelda's shield that is impenetrable to all except the most powerful of dark magic, then sends him bursting into flames with Din's Fire. As I recall from Pitch Black, Riddick isn't particularly fond of bursting into flames, is he?
