Toxicat

Goes by many names bc they don't know their name. They use the ones others have used for them. Toxicat as a name functions more as a title like the cheshire cat. Other names for them are Tiris, glitch, shudder, dust, tar, pitch, void, creature, observer, abyss, star eater, and kitter or they are simply called nothing and are nameless. This is the list of names created by thousands of years of wandering through many universes nameless and being given a title or name by those who come across them.

Toxicat is a rather lost creature. They do not know who or what they are just that they are. They know that they like stories so they content themselves to watch and be an observer. They discover what they like and dislike over time but almost everything is a new experience for them. Though at the very back of their mind they have this pulling aching feeling of something missing that they can't place. 

Toxicat has several forms or variations of their two main forms; Their feral form and their anthro/humanoid form. They remain relatively consistent however. Same blue, yellow, white, and black colors. Void black head with pure white eyes. Black teeth with a white mouth. Always feline in shape even when humanoid some traits remain. They use a suit to be able to touch living things as their body is incredibly 'toxic'. The suit forms to fit their body after the helmet is put on. 

Toxicat has many abilities including dimensional and universal teleportion/teleportion, creating objects, dematerializing them at will, form shifting, ect. It wouldn't be inaccurate to simply label them as a God. Their teleportion unfortunately is not fully under their control and for reasons unknown to them at times they will simply blip out of existence into another universe or into a void. 

Toxicat is functionally immortal. They never age and can not die. They can however still be wounded. Severe enough injuries will cause them to 'melt' into what looks very similar to slime or tar, though they still somehow have cat like ears. In this ooze form Toxicat can be scooped up into a jar but due to their unstable nature they might just teleport out. If Toxicat's ooze form were to be atomized they'd still pop up somewhere else. Perhaps their true form is not in any material realm? 

They are the cold death of the universe personified. The eventual death of everything including the very last black hole leaving only a void. They don't know that though. The helmet confuses them and only with it off do bits and pieces slip through but when the helmet is off they kill things by accident so they keep it on. Their uncontrolled universe jumping further confuses them as to what they are. Their original universe, the now dead cold void they came from, is lost to them. So they think that the reason things die when they touch them is because they must be toxic.
