A Mega Boss is the undisputed leader of his Ironjawz. Hordes of orruks follow the mighty warlord into the heart of the battle where the best fighting takes place. Clad in layers of iron and armed with massive weaponry, Mega Bosses take great delight in defeating enemy champions while their barely contained Waaagh! Energy drives her boys insane.
It is well known among the Ironjawz that the more battles an Orruk wins, the thicker its muscles become, and the longer its body grows, the longer its teeth grow. Understandably, then, Mega Bosses are massive, so huge that they outshine even the mightiest opponents. Some Ironjawz believe that the reason mega bosses are the biggest is because Gork (or maybe Mork) is inside them trying to get out. Supposedly, when they grow up enough one day, they will become one of the gods themselves and go about knocking down mountains or stomping on fortresses. Others say that mega bosses have always been the greatest, following the well-established Orruk logic of "that's how it was when I found it".
Ironjaw Megabosses are extremely brutal warriors. Whether clattering on foot or roaring from the back of a Maw-krusha, they knock down foes like a landslide of fists. Given their size and unparalleled combat prowess, Mega Bosses wear the heaviest armor and have the largest choppas. The best pieces of iron from the battlefield often find their way to the mega boss, where he smashes them onto his body and gives his armor its own armor. In addition to layers of the shiniest iron, mega bosses pound away trophies - the skulls of tough-looking creatures, bits of broken weapons, or symbols torn from the banners of enemies that looked important.
The power of a mega boss isn't just in brawn and iron, and as focal points for the Waaagh! They have a bestial aura that attracts other Ironjawz from all directions. The destruction caused by a gathering Waaagh! is often almost as bad as the event itself.
Competition between mega bosses is common, often involving headbutt contests, orruk slingshots, or kill lists. The latter practice is particularly controversial, as only an exceptional megaboss can keep track of the numbers involved after the opening moments of a fight. The competition generally ends in much shouting and, inevitably, fights.
