I wrote a better sci-fi anthology story in like twenty minutes (I haven't revised it so pls no bully)
It is now 2252.
Conrad boarded the small mag-lev train, and promptly sat down at the nearest open seat. With a light shudder, the locomotive lethargically began to accelerate in a process that would go on for hours. The passengers, vividly colorful and strangely polymorphic, stared curiously around the visual space Conrad occupied. They couldn’t directly see him, but they were aware of a large, foreign presence within the area. This was not a mistake. His jagged, trash-heap exoskeleton was certainly “foreign” when compared to the passengers’ sleek, abstract forms. Conrad’s golem-like appearance served to only hide the organic marvel inside: a fully-intact human body. Under the incomprehensibly intertwined layers of wire and old computer components, a naked man stoically persisted. The Others, the passengers around him, as well as the whole of humanity, had shed their skin, muscle, organs, and bones for bodies of multicolored plastic and metal, which they piloted from their brain-stem. In essence, they were brains-in-a-jar, and although this eradicated many of the burdens of Being Human, many people (such as Conrad) affronted the idea. Personally, he was disgusted by it, not only because of his personal politics, but also one major flaw the concept posed.
A bomb began to tick. It slid out from under one of the seats and planted itself firmly on the cabin’s floor, in plain sight. Nobody seemed to notice, except Conrad. He briefly panicked, but relaxed greatly after a second-look. The bomb continued to tick, and a small whine gradually grew louder. He smirked in nervous anticipation. The whine was now roaring over all of the passengers’ chatter, but they still didn’t hear it. The noise came to a peak and then immediately ceased.
The small screen strapped to Conrad’s face gave out. He attempted to move, but immediately felt the weight of the armor fight back against him. Using his tongue, he flipped a switch back and forth. With a few whirs, the suit and it’s components revitalized themselves. Conrad looked around himself, and realized all of the passengers surrounding him were inactive. He bent over and interfaced with one of the systems, halfway restoring it. “ARTIFICIAL LUNGS NONFUNCTIONAL – GREY MATTER COMPRIMISED.”
Standing now, he chuckled and exited the train.
