A shark rictus for an eye, hidden under an eyepatch.
Yellow cyst like sores that occansionally break and release “harmless” flies.
The top half of the strangers head (top jaw up) is a candle/Pearl/gem that radiates a pleasing, soothing, violet light.
Transparent skin (to what extent it’s present is up to you).
A mouth that extends ear to ear.
Stain glass finger nails/hair.
Two faces on one head
Several rows of differing animal teeth behind the human ones.
Scales. Scales everywhere.
The tycherosi arm is made of glass and is to all appearances hollowing. A different substance/organism replaces the hollow space each time they sleep.
A transparent film is over the skin/tissues covering the Stranger’s heart. In place of their heart is a scale model of a leviathan hunter ship, always tossing about in a squall.
The strangers facial features have limbs/umbilicals and constantly crawl about their head.
The Stranger talks w/ a chorus of voices, some old, some young, some pained some ecstatic.
Hands for feet.
Fly limbs for eyelashes.
A crown of avian beaks, each beak from a different bird. What do they say?
Whenever the stranger gets physically hurt the wound heals fine, but replaces the wounded tissue w/ plant/nonliving matter (steel cable for muscle fiver, bark for damaged skin etc.)
The Strangers skin changes to a new, outlandish colour during the course of every day.
The strangers hair is luminous, like the broken sun.
The stranger has a third, smaller arm in place of their tongue.
The tycherosi has differently sized handprints all over their body, some look like burns, some look like makeup, some look like handprints pressing up from the inside. The fingers on each “hand” move and quiver.
An animal tail.
Skin that flakes as drops of bioluminescence. Skin flakes that turn into shreds of paper w/ one ominous word on them before rapidly decomposing.
Insect/Mollusk chitin.
Arms that have an extra elbow like Steve Erickson’s Forkul Assail.
I’ve found that China Miéville’s Remade make for some really good inspiration for tycherosi features, but that also maybe me projecting a bit of Bas-lag’s weirdness onto the Dusk
