Age: 30-ish. ... I think. Rough estimate since we're basing this off of Spirit's age and Stein is actually his JUNIOR. So.
Medical Info: . . . lol. Physically healthy, mentally insane. But not out-of-control-y kind of insane. That's for when he really cuts loose.
Appearance:
Comme ça. Though shirts may vary. Giant screw in his head, stitches all over his body, white lab coat riddled with stitches, glasses, and oftentimes smoking. Tall.
What's Okay To Mention Around Him/Her: Pretty much anything. He's heard crazier.
Abilities: ... so many to list. I'll break it down.
-Hand-to-hand: a very capable fighter when it comes to just pure blows. He is well-trained in martial arts and other fighting styles. He can also play dirty and use his soul-wavelength-malleability against people.
-I Can See You~: just about as creepy as it sounds. He can totally see your soul, dude, and it tells him some things. Not a lot of things, just blatant personality types and things like whether or not a person is uncomfortable (because that's really the most important thing, you know). What he infers from this varies depending on the person and conversations he may have with them while studying them. And believe me, he is always studying.
-Soul Wavelength: one of the most talented things about him is that he can literally adapt his soul's energy (re: wavelength) to match another person's. This enables him not only to be capable of utilizing any weapon that is willing to work with him (or even maybe unwilling since Spirit... but then again... masochism...), but able to completely cancel out another person's attack (hi there, Black*Star).
-SCIENCE: he is well-versed in it and is very intelligent! We're talking genius-level. However, his expertise lies in taking things apart primarily. Not putting them back together. ... unless it's in an interesting way worth studying. And sometimes when a person really needs a hand (lolol).
-CRAAAAAZY: This is totally an ability. Stein is insane. Literally. He is steadily slipping further and further down that slippery slope but gosh darn it, he is resisting! Because Shinigami needs him to be sane. His students need him to be sane. And yet he is totally wanting but not wanting but SO wanting to go nuts. It's kind of a thing. Ask him about crazy things, he is well-versed in this as well.
Notes for the Psychics/Magically or Spiritually sensitive: Aaaall of the above and then some. He is not a psychic himself but he is able to sense other people's souls' energies. So take that as you will. One thing for sure: You can sense that he is a VERY POWERFUL person. And capable of a lot more than he seems. Ping me if you ever want specifics (such as before Stein left Camp the first time, he totally got his soul ripped in half and pasted back on yey. sooo...)
Minor in-thread violence/etc: I do not mind at all! Just a quick head's up will wooork~
Hugging/kissing/other non-violent physical contact: . . . go for it. Little kids will get off easier, for some reason. Maybe.
Maim/Murder/Death: Piiiing me and let's talk it out~ I've played things like this out with Stein before and I don't mind as long as I know what's what.
Cooking: ... he makes things in beakers and test tubes, probably. Is that safe? You can always be the taste-tester...
And if anyone's interested in some of the things I've essayed (including particular relationships he found most interesting/important) on before when I last played Stein...

"Meister" is the generally accepted term now.)
