The Morkanaut is a towering Ork walker, a bipedal war-engine hammered together by the Meks in the image of the god Mork, all hulking armour plates, belching engines and guns big enough to make even a Nob grin. It wades into the thickest fighting shrugging off hits that would gut a lighter machine, protected by a kustom force field that flickers and sparks as it soaks up incoming fire and shields the mob of boyz stomping in its shadow.
Its arsenal is pure Orky excess: a kustom mega-kannon that spits searing blasts of energy, batteries of big shootas and rokkits, and a colossal klaw for tearing open tanks and bunkers like tins. Some carry a transport bay crammed with warriors to disgorge amid the enemy line.
For all its bulk the Morkanaut is a thing of brutal momentum, and once it builds up a head of steam nothing short of a shell through the boiler will stop it. To the greenskins it is proof that biggest really is best, and to everyone else it is a slow, unstoppable doom that grinds closer with every earth-shaking step.
