(For the record I used the "questionable" fanart from the Eternitydev wiki as a basis for this because idky but that design gives me neuron activations)
(Also hey! This is technically the first of these dudes to come from TWO different games! so that's neat!)

Two sixes indicate that this is the 12th day of Tauttober!~ One away from the unlucky thirteen, but everyone affected by this marathon of pressure is anything but~

A strange automaton that was once locked within a bunker had now been roaming Earth's countryside for quite some time now, whether it was an experiment gone wrong, an extraterrestrial being that was left behind, or something not of this dimension entirely, it didn't matter, as it was truly something few had seen either way, what with it's patchwork form, bladed limbs, and bizarre sense of tracking, it became known as the Antibreather by the few to have seen it. Strangely enough however, it had become less hostile than how it was in containment. Going from slashing throats to simply knocking away anything that got too close for comfort.

Of course...a researcher in the area became curious about the cybernetic aberration, and began to track it, learning more about how it functioned and what it was doing. It was worth getting knocked around by it to learn about just what the thing was! One night, though...something very interesting happened. The researcher wasn't sure why...but they tried to offer the being a burger they were holding onto for a mid-expedition lunch...the Antibreather scarfed it down...and was practically OVERJOYED by it! It's movements becoming far more excited as it galloped in circles around the researcher.

The researcher learned just what the creature wanted, it was hungry! Naturally being so beyond typical nature, and unable to pick up objects thanks to it's scythe-like limbs, it likely had a difficult time picking up and consuming things...and so, they vowed to be the one to continuously sustain it...~

As the weeks went on, the creature consumed more and more, The researcher had gained it's trust and, eventually, learned enough about it to replace many of it's more damaged, rusty mechanical parts, with more versatile equivalents but that wasn't all! Soon...the being began to balloon...~ It's new limbs swelled up and smushed tightly against it's rounding form...it's face and head merged together as it's sunken in eyes POPPED out into massive bulging balloons...~

In essence, it had gone from a bizarre, potentially dangerous mechanical beast, to little more than a goofy, gluttonous blimp of rubbery flesh and latex machinery~ The researcher even eventually wrapped a mawashi around it's waist to increase just how comfortable it felt. It's movements becoming lazier and sillier by the day, eventually needing to raise it's whole body up on one rounded off foot and slam down on the other like a true sumo, just to take a single step!~ It felt simultaneously humiliating AND incredible, like a constant high~

As it grew past the treetops, it still demanded more and more...and more it would receive as entire feasts were fed to it on an almost hourly basis, what constituted a single day's meal for the Antibreather could feed an entire village!~ As it rose and rose, it could faintly see other, strange, overwhelmingly taut beings in the distance...all of them engorged and swelling to humongous proportions, just like itself...~
...
For quite some time now, it had no interest in hunting for sport nor food...but it was happy that it would have opponents to slam taut forms with in the near future~
===========================================

Goodness I'm sorry that this is such a WEIRD choice, but as someone who has known about this dev's games even BEFORE they got big with Voices of the Void, I wanted to take a crack at doing something with them, and didn't just wanna go with the obvious choices either(Though I still might do so later~)

Well, that, and I always had a soft spot for this weirdo ever since I first saw them :p
