The primalspace is a place where all form of life can begin. That's where he comes from. It's a primitive broth where all souls begin material life. That's how Bazttattath came to be. He was basically a bacteria that fused with a parasite and a soul that began growing and growing to a human size. He is very like a mircoorganism but with a lot of different features too. He has what looks like spikes all over his body, but they're actually bacteria fimbriae. He has a sharp pointy tail which he can stab other organisms and even things with which he can use to extract nutrients from. That's how he thrives. He basically injects his tail on some host organism and basically infects it, extracting nutrients and other proteins to feed itself. Most hosts don't realize they've been infected but they present different kind of symptomps. Some of them are excessive tiredness and loss of weight with an increase in hunger. Some mild coughs here and there and sometimes diarrhoea. All of these are effects of Bazttattath eating away all the nutrients of the host and basically duplicating the amount of waste both produced by the host and Bazttattath himself. Aditionally, Bazttattath is an anaerobic microorganism, which means, it doesn't need oxigen to live and as such he doesn't have a respiratory system. He has a weakness for antibiotics and antiparasitic medicines, which is one way to get rid of him. More about how he infects hosts, he has different states while he infects people. The first and most common state he lives in while infecting people, is the dormant state, where once he punctured with his tail and becomes stuck to them and begins feeding himself from the host, he will enter a sleep state, where his body will form like a layer of some thin transparent film around himself and it will begin producing some fluid, basically making like a sack where he floats and sleeps just like an embryo. The second but most uncommon state is the aggressive state. He mostly enters this state when the person infected realizes he is present and decides to medically treat themselves. He doesn't always enters this state when that happens, most of the time, he will leave the host when he learns this information. But in some rare cases, if he isn't feeling like it, he enters the aggressive state where he will go full disease mode and start producing and injecting the host with harmful compounds and antigens. Symptoms present in this state are a lot more serious including a bad cough, a very bad fever, some veins becoming black, some random and spontaneous bruises, some anomalous eruptions on the skin, big headaches, internal bleeding and even worse symptoms (prolly like organ failures and others).
Finally about his personality, he is very chill and smug. He is very avoidant at times and just stares from a far how other people interact between each other, having usually some dellusions of thinking that people conspire against him with the purpouse of not being his friend. And he generally has a stalky and creepy behaviour towards them and has gotten in trouble in the past for that. Anyways if u read to this part, hallo! and hope u have a nice day xD,you have Bazttattath's blessing that u won't get sick and if u are sick, u will heal soon <:
