ImTired
Of all the orc duels, only a few were exciting.
As honorable mentions we have:
-Prak the Slippery against Luga of the Spiders. At the last moment Prak slipped, which caused him to fall backwards, his legs accidentally hit Luga who got knocked out.
-Krosh Hot-head against Müg The reckless. Krosh won the fight by lighting Müg on fire with his torch -helmet. Image of how such an helmet looks like.

And then we reach the finals: Two champions who swept the floor with every opponent they faced. The first contender... Lorm The Large. Brutally trowing his opponents around the arena, sometimes not even using weapons he crushed his opponents.
The second contender... Gund Champion of Gorgoroth. As his name says, he truly is a formidable orc. With his dual burning blades he elegantly moves through the arena disarming his foes in seconds..
Who will win we shall see...
The two step into the arena...
"You think you're tough? Well, I'm tougher!"
Lorm taunts.
Gund doesn't let him walk away without taunting back.
"The crowd screams for you, I will make you scream for them!"
They storm at each other, as expected Gund tries to disarm Lorm and succeeds. But he didn't count on the fact that Lorm let him do that, se he could do his trademark-move. He headbutted Gund, grabbed him by his troat. He held him in the air just not long enough to choke, and tossed him across the arena, head against the wall.
Knock out!
And so Lorm The Large claimed victory, and he would be the one to fight the puny human, or that is what he believed Sokeyr to be.
