The Megahut is a relative to a jaba the hut (star wars) it is a big, fat, greasy, gross, Q. with 3 large cannons on its back.
One of the Megahuts first appearence in a Spectacular movie was the 2007 movie "Dragon Wars." It appears when the guy who speaks alienese summons his soldiers.
dont shoot the soldiers, on a count of the fact that their shields are bullet proof. and you apperently cant shoot anywhere else.
