A response to @feministfandomgeek ‘s comment; the response was too long to be a reply :)
This is a part of my Monster Town series. Part one can be found here
Most monsters can be categorized in one of these three categories:
Humanoids
Humanoids look identical or nearly identical to humans. Any powers they have maintain their form.
Robin- Ghost; when she “goes ghost” her general shapes stay the same, even though she’s invisible and can go through surfaces
Will/Johnathan- Banshees; when they scream, their scleras turn black and their irises turn yellow. Otherwise, they look the same
Glamorists
Glamorists have a generally humanoid shape, but with noticeably inhuman features. Because of this, they have to wear glamours (think TOH galderstones) to cover up. Glamour charms usually last up to 1-2 years, which means they must find a local witch to renew it (The more specialized to them though, the better) before it fizzles out.
Eddie- Witch; pointed ears, fangs (top and bottom), purple slightly-glowing eyes (color varies per witch, and is the color of their magic)
Max- Dryad; moth wing-like ears, blunt fangs, clear “blood” (sap), (if one looks close) bark-textured skin
Lucas/Erica- Vampires; pointed ears, dark claw-like nails, double sets of fangs (top only) crimson glowing eyes (color varies vamp to vamp)
El- Angel; large white feathered wings, halo light she can summon at will
Shifters
Shifters usually have two forms (but can have more) and can generally shift at will anywhere between any of those (depending on species-specific restrictions). Their monster form is considered their “natural form,” as if their human form is like a physical glamour.
If shifters spend too long completely in human form, they’ll spontaneously shift back to natural form, as well as other species-specific side effects. In order to stop this, many shifters will “half shift” to a humanoid form with monstrous features.
Steve; Siren- his parents coaxed him into a masochistic habit of “binding” his form to the point where he’s used to and doesn’t realize he’s unhealthy
Dustin; Werewolf- his mom formally taught him how to form shift, but Steve got him more comfortable with it and taught him half-shifting
Argyle; Shapeshifter- his human form is his natural form, with his second form being “the unknown”
Nancy and Mike are humans descended from Valkyries. Because of this, they have extra insight and can physically comprehend magic like monsters. Nancy is also really good at persuading people to tell the truth.
Because Hawkins is a monster town, Glamorists don’t need to wear glamours, and depending on their natural forms, Shifters can half shift or go fully natural without weird looks or persecution.
