Age: Unknown-- physically he's a youth around teenage years, and time is kind of funky in Nocturne in dealing with before-Conception, time since Conception, etc.
Birthday: None.
Height: Not terribly tall for a guy -- 5'7" maybe?
Weight: 150 lb or so
Eyes: Unknown, but presumably the same pale blue-gray as the rest of the Manikin.
Hair: Unknown, but presumably the same brown-black as the rest of the Manikin.
Medical Info: Well... he's made out of river clay technically, but he's also got perfectly normal skin, blood, muscles, bone, etc. Also that spasming is totally not unhealthy rly.
Physical traits: Well... his skin is a uniform grayish white, like the color of fired clay, his head is always tilted as if he's staring upwards instead of looking at someone directly, and every few seconds his torso spasms. Other than that, he looks pretty much like a normal slender-ish teenage boy!
Abilities: NOT MANY. The closest he has is an amazing ability to find all sorts of weird and useful junk. Spoon that can instantly dig through cement, anyone?
Notes for the Psychics: O-okay, you know how the Nobodies feel like "Soul + (temporary) Body - Heart"? He feels like "Heart + (temporary) Body - Soul". Lots of emotions! He's a very feeling guy! No actual soul, if you can sense that sort of thing. SPOILERS IF YOU'RE ABLE TO GO DEEPER: When the Conception (apocalypse, basically) occurred, almost all humans died. I mean, to give you some idea of how many, there were... uh, 6 human survivors? Basically. And the human souls went on to wait to be reborn when the world was remade etc. However, some people had such strong emotions that those lingered and ended up taking on their own makeshift forms. They're of varying levels of strength, but the Manikins are basically remnants of human emotions. However, I note that the Collector isn't aware of this.
Can I shapeshift/bodyswap/spit at/step on/etc?: Sure, just ask first. Well, you don't need to ask to spit at or whatever, but shapeshift and bodyswap, yes!
Maim/Murder/Death: Sure! Let's just talk it out.
Cooking: Probably, though it's probably pretty basic cooking.
Kissing/Hugging: Go right ahead!
