The Mutant Mothership is the ship in which the Mutants came to Third Earth in. It is a very large ship, accommodating many Mutant troops, as well as a number of Mutant vehicles. It was sunk into the Desert Sinking Sands by Mumm-Ra.
The Mutant Mothership had many capabilities. It was shown in "Exodus" to have abilities to carry many small Mutant Ships. It had grabbling rays to hold a ship to board, and an air tight glass tube to help aid boarders to make the hole in a ship to get on the other ship. A transport beam can also be used under the ship.
