The New World

He drinks solvent and breaths combustion. Instead of simply dying when his body runs out of nutrients and calorie stores, it has begun to Digest Itself. His body is pumping chemicals they do not understand and every chemistry panel they run shows new levels of new chemicals and hormones. The human body replaces most of its cells constantly because even breathing, especially at a higher atmospheric pressure, is destroying their own lungs.

This thing "hears" things they cannot comprehend and he is unable to describe beyond "color" and "brightness" which are things you can not contextualize, and calls the strangest things beautiful. It has no entirely discernable traits you can understand ecologically as a predator- no armor, no weapons- and yet it eats meat and that is one of the many nutrients it needs to survive. You as a resident of erid do not have many creatures with "eyes" and so have no idea that the strongest mark of a predator is neither claw nor fang, but forward facing eyes, all the better to catch your prey, to meet a foe head on and fearless. You just know it "sees" and that it eats meat, and many other complicated things.

And in place of not receiving all those nutrients, it's body will litterally digest itself and keep going without them. Oh, this new chemical in it's latest blood panel allows it to ignore it's own pain to the point it won't realize it's injured. It can wake up from a dead sleep if you are too loud or too "brightness" around it. It speaks in an archaic graveling noise and is capable of imitating the strangest things, including a haunting near-vocalization of the eridani language of its own, which it calls "singing" and it does this at the strangest of times, when happy and when nervous. It is neither fast nor slow, but over time and observation, you realize this strange towering bipedal creature expends an entirely minimal amount of energy to walk, a process of controlled falling turned mobilization. You hypothesize that for lack of predatory weaponry like claws or sharp teeth, this thing simply evolved to follow you. To "see" you with it's forward facing eyes even in total stillness, total silence, and follow for as long as it takes: it won't spend much energy, and it won't starve waiting for you to exhaust. It'll start digesting *itself* while waiting for it's prey to lay down and have to sleep. It will "watch" you sleep with "eyes." You cannot wake up the way it can, and it will eventually catch up to you.

Also sometimes it cries excess amounts of saline rich solvent when you compliment it's latest research paper. Rocky calls him an idiot and the overseeing eridian scientists watch on with a sense of morbid eldrich horror. Right, right, just a "leaky space blob", sure.
