These Gorkanaut and Morkanaut models were on display at Warhammer World.
The Gorkanaut possesses all the unsubtle brutality of Gork along with a blocky silhouette that looms menacingly over friend and foe alike. Piloted by an Ork Nob, this hulking orkoid armoured war suit is the epitome of everything an Ork aspires to be: Massive, tough, loud and destructive. The Gorkanaut’s main weapons are the deafening and deadly Deffstorm mega-shoota and the massive armoured Klaw of Gork (or possibly Mork). It is also armed with two twin-linked big shootas, two rokkit launchas and a skorcha.
The Morkanaut’s main weapon is a profusion of worky gubbinz and zappy bits known as the kustom mega-kannon. It is also armed with two twin-linked big shootas, two rokkit launchas, a kustom mega-blasta and the Klaw of Gork (or possibly Mork).
Still not entirely confident about the differences between the two, but I think that’s the point.
I have considered buying one of these for my Ork forces, but it has so far remained on that long shopping list of wants.
