Heavy infantry unit.
The richest and most battle-hardened Nobz can become Meganobz by paying a Mek to build them a suit of mega armour. Piston-driven and covered in enough protective plating to turn its wearer into a walking tank, this armour is incredibly expensive. Yet it serves as the ultimate greenskin status symbol. Though other Orks mock the Meganobz for wearing so much armour, only the dullest would do so within earshot. Even a direct hit from a tank round is unlikely to do more than knock a Meganob over, worsening his already foul temper. For many, the only chance of surviving an encounter with an angry Meganob is to outrun him.
