Metal Alien

By combining the fearsome firepower of the High Speed Tank Booby with the bipedal versatility of the Buried Surfacing Cannon Gulcan, Red Falcon's traitor engineers have created a war machine that is somehow less than the sum of its parts in every conceivable way. Prone to tumbling over due to its top-heavy design and unable to pivot its main turret up or down, the pilots of these botched battle vehicles rely on clumsily stomping their enemies underfoot as the most reliable means of victory. Every member of Red Falcon does, however, remark on how cool they look and how badass it feels to drive one of these horrendous Frankenstein's hot-rods.

Engineered to be the perfect metallic killer amongst an army of tyrannical alien invaders, this nightmare has only one weakness: rust. Also, it can be brought down by shooting it a lot. This is less a weakness and more a fairly universal property of matter barraged by high speed munitions.

When the Aliens first made contact they struggled to overcome humanity's innate distrust of the other, making brainwashing more difficult. Initially they began bio-engineering a pseudo-human to act as their mouthpiece, but scrapped the idea as humans didn't seem to particularly trust other humans either. Here we have attempt number two, inspired by humanity's near universal trust of canines. The human face was a design misstep.
