Gorkanaut
The Gorkanaut is a massive, blocky, primitive battlesuit created by the Mekboyz and piloted into battle by lone Nob. Sporting myriad heavy weapons, in the form of a pair of twin-linked big shootas, a deffstorm mega-shoota, twin rokkit launchers, a skorcha and a suped-up power klaw, the Gorkanaut is a brutal engine of destruction that serves as a living avatar of Gork upon the battlefield. Although in many ways a super-sized Deff Dred, its size allows it to carry up to half a dozen passengers in its armored belly, heaving them out to begin the slaughter on their own before getting back to fragging shit.
The Gorkanaut's brother is, of course, the Morkanaut.
