Character scents?

Ky Kiske There's always a scent of ozone no matter what version, a bit of petrichor (that after-rain smell), he also generally keeps up with good hygiene.

SCP KY doesn't like perfume or scents, so he'd just have the ozone, petrichor, clean soap smell, and maybe a bit of sweat if he's been very active.

DB KY however, since hygiene and smelling good was very important to the medieval times, he's the guy who uses herbal essences and prefers scents that are considered feminine by modern standards, so he has the ozone, the petrichor, but also he'd always be smelling faint of flowers and citrus

....I'm just imagining Ky's fan club in DB just going wild for that.

Because you know Ky probably has one

oh he definitely has one

haha

Sherlock smells faintly of tobacco and chemicals. In canon, he'd have an herbal-floral scent due to the hygiene products of the hair (hair oils had lavender, rosemary, orange-blossom and almond oils mixed with bees wax) - that's of course when he's being himself, he's very careful to decent himself or use other scents in disguises.

in DB there's a faint iron scent of blood no matter how well he cleans himself, and in both SCP and Daybreak the rare times he puts on cologne, he prefers warm, spicy kind of "gentleman's parlor" type scents.

Sinbad I always HC to have the salty ocean-spray scent, his hair having traces of argan oil as he takes care of his hair, as a teenager he's constantly experimenting with different perfumes and colognes, maybe applying a few a little too strongly.
