Gutterbot Duo

The Guttergirl and Guttertank are a pair of war machines that have been repurposed for security after the New Peace. They're built with curvy & thick female bodies – the Guttergirl is more chubby and top-heavy, able to produce milk, while the Guttertank is taller and more bottom-heavy, able to manufacture a metal "male part" that goes between its legs. They're fierce, vaguely erotic rivals. The Guttergirl switches between Russian & English, and the Guttertank occasionally speaks German.

The Guttergirl is a bulky humanoid machine. Its head is a silver dome with several wide lenses, bearing a resemblance to old Russian diving masks. Its waist is covered with some kind of black metal, while its wide torso, huge breasts, plump belly and parts of its limbs seem to be made of a flexible dark gray material. Its darker nipples are pierced with square metal chain links. The rest of the Guttergirl's form is adorned in rusty-brown plating. Red lines, markings and lights detail its body. It has short stubby feet and wide soft hips underneath its armor. The Guttergirl's right arm is replaced with a minigun, as it was originally used for clearing trenches in the Final War. Meanwhile, its left human-like arm holds a large, body-height shield composed of brown armor plating, designed to protect it from enemy fire. On its back, the Guttergirl carries a large metal coffin-like device, which contains systems that pump its insides with blood to keep it fueled. Similarly, it has mechanisms inside its heavy breasts, designed to produce and pump out synthetic milk. The Guttergirl was designed in Russia, as evidenced by Cyrillic text on its shoulder reading "ЧТ-01" (which stands for "ЧЕЛОВЕК-ТАНК 01").

Built in the early days of the Final War, the Guttergirls were one of the first successful experiments in using blood as a fuel source, as well as the first automatons to be deployed in wide-scale conflict.

During the War's first phase, an era of trench warfare, these seemingly unstoppable walls were airdropped into enemy trenches, which they would then slowly and systematically clear out as all opposing soldiers would have to choose between being minced by the Guttergirl, or running out of the trench and getting mowed down by machine gun fire.

Researchers had not yet found a way to keep blood inside the machine fresh, so a live fuel source was strapped inside, kept alive by minimal life support, before the Guttergirls were welded shut. Although publically these fuel sources were claimed to be volunteer patriots, most were deserters, battle-fatigued returnees or prisoners of war.

When the New Peace finally came about, the Guttergirls were long obsolete, though some still remained in operation, and were repurposed as security machines. By then, they were retrofitted with a far more humane fuelling system, one that did not necessitate the use of live blood sources.

=========================== The Guttertank is a bulky, humanoid machine with bright red angular armor that has some white and golden bits. It bears a strong resemblance to its counterpart, the Guttergirl. However, in comparison, the Guttertank is taller and more bottom-heavy, having wide hips, fat thighs and an oversized rear end composed of a flexible gray material. Its breasts are smaller compared to those of the Guttergirl, and are hidden underneath the red armor. Its head is a red angular helmet with long black slats used for vision. It has an oversized rocket launcher on its right forearm, which is connected to a large white steaming tank mounted on its back, used in the process of synthesizing ammunition like rockets or landmines. Furthermore, this tank can also be used to manufacture a vaguely rocket-shaped metal "male part" that goes between the Guttertank's legs and acts as a fully functional appendage. Meanwhile, its left arm is more human-like, and has German text on it, reading "FAUST PANZER" (which loosely translates to "FIST TANK"). Its feet are covered by angular red armor "shoes".

As Guttergirls singlehandedly ended the trench warfare era of the Final War, armies scrambled to create countermeasures, leading to the creation of more machines of war.

Built from the foundations of Guttergirls to save time, Guttertanks were equipped with highly efficient explosives and arms capable of damaging and destroying thick armor. The slow, lumbering walls that once dominated the battlefield had now become obsolete.

As human soldiers had quickly become useless in war, utterly outclassed by machines, they were almost entirely phased out. This led to the second era of the Final War, where machines fought machines in a back-and-forth tide as new designs were phased in and out at a feverish pace, each designed specifically to counter the last.

Although at first the soldiers celebrated returning home, they soon found that the pointless, endless arms race left little in its wake. All resources were used on machines of war, and impoverished civilians had to struggle to survive. Home was just another battlefield, a war of all against all.

Years upon years had passed before humanity realised its folly, and when it was at the very brink of destruction, the Final War came to a quiet end, thus beginning the New Peace. By now, Guttertanks have been divorced from their past duty as bringers of death, and are used for security purposes, though still retaining their weapons.
