Location from Ben 10 by Man of Action / Cartoon Network
Vilgax's command vessel — a massive warship crewed by Mechadroid robots, equipped with weapons systems capable of planetary-scale devastation, and perpetually positioned just outside Earth's immediate vicinity.
Vilgax's ship is the recurring threat in the background of the Original Series — the place Ben's adventures are ultimately aimed at, the source of the Mechadroid attacks, the thing that will arrive if things go sufficiently wrong. It's been damaged twice severely enough that Vilgax was believed dead. He was not. The ship was repaired both times, because Vilgax's commitment to the project of getting the Omnitrix does not scale with setbacks. In Alien Force and later, Vilgax has upgraded the ship's systems considerably. He's had time.
A large, dark warship with angular alien design — built for intimidation as much as function, with weapons visible on the hull and the general aesthetic of something designed by someone who wanted people to feel hopeless when they saw it approaching. Internal corridors are utilitarian and cold, lit by dimly glowing panels, populated by Mechadroids that move with mechanical precision.
Also known as: The Chimeran Hammer, Vilgaxia Command Ship
