Deimos-9

Deimos-9 is a large tripod machine built by the Martians to reap any material left in the wake of the Mothership, but can grapple with any target with those same arms used to reap resources.

Lore
The enigmatic tripod walker craft known only as Deimos-9 would follow after the Ares Mothership and continue the process of harvesting resources while expeditiously dismantling Earth’s defenses. Impacting initially in a compact spherical form, it unfolded to reveal its long legs and extending manipulator appendages, proving it could swiftly cross any terrain as it focused on urban centers. Deimos-9 has shown the capability of reaping vast amounts of energy in minutes, and seems to prefer to prey on power plants, solar grids, and other high-energy locations. Its grappling manipulators and limbs are made of advanced Martian metals and polymers, being extremely strong and durable despite a fragile appearance.

Trivia
