I have a few oddly-specific flavors (note that these apply to both canon characters and personal OCs):

-Proud aromantic-asexual brunettes - often female, with some exceptions - with a tendency to utilize fear in one way or another, and often have a few select people in their social group they will do anything for, even if they don't outwardly show it. They can be monsters or humans, and they often have unpleasant aspects to their personality that make them feared, be it making someone else miserable, the ability to kill someone in under five minutes, literally causing fear by existing, or flat-out being unable to relate to other people, and treating them more like guinea pigs. (Canon example: Scarecrow from the Batman comics).

-Sweet, sensitive, creative souls who have a specific thing or two they're good at (wood-carving, bartending, playing music, etc.), and often have a disability of sorts, or something else uniquely different about them (blind musicians tend to be a favorite flavor under this particular umbrella). They tend to be friends with the aforementioned aro-ace brunettes. These creative souls often have thick skin and can hold their own, but fuck with them at your own risk if you don't want a literal fear demon on your ass on their behalf because you hurt them. (Canon example: the Disney version of Quasimodo. He even fits the "friend" criteria: While Esmeralda isn't aro-ace, she's a brunette, protective of him, and feared because of the assumption she's a witch).

-Men who are a decade or so older than the woman they're in a (platonic or romantic) relationship with, and actually [i]are[/i] chivalrous, protective gentlemen. He could have married his young wife to get her away from her abusive family, and then let her do her own thing under the protection of their marriage, bent society's rules to marry her so they can hang out as friends without being questioned, be her mentor, etc. These are often sexless relationships, but in the rare time it goes there, he lets her initiate and follows her lead (Scarecrow, again, fits here. He has a tendency to find 20-something girls and legitimately platonicly assist/mentor them - though his help may not always be wanted. XP). A subset of this flavor (age gap optional) is men who are obsessed with their dead/otherwise incapacitated partners/friends, and may end up losing themselves in their quests on her behalf (some popular canon examples: Severus Snape, Mr. Freeze, Nathan Wallace/Repo Man).

-Polyamorous trios of mixed genders, but with two members of the same (or present as the same) gender. Often, one of the two of the same/presenting gender will be a switch, and have a deeper relationship with the other of the same/presented same gender, but all three will be good friends. For example, in a M/M/F, M1 will be bi/pan, M2 might be gay, and they'll be closer romantically. F will be friends with M2, but team up with him to lovingly troll M1 during sexy funtimes. And then after sexy funtimes, they'll all wreck each other in video games, or cook together, or go on an adventure, or otherwise hang out and act like a friend group.

-Trolls and tricksters who start shit just because it's funny/otherwise worth their efforts, but often have depth to them. They enjoy causing chaos, but aren't out to actually hurt anyone, just to have fun, fuck with them, and/or prove a point. They do whatever their whims lead them to do, but tend to know when they've gone too far. That said, they're still going to start another round of trouble. It's just what they do. (Canon examples: Lock, Shock, and Barrel, the Riddler - but specifically versions where he treats crime like a game to prove he's smarter than Batman, uses death traps as a lure, and isn't out to [i]actually[/i] kill/hurt his pawns too much. He just knows it'll get Batman's attention [there's one comic where he threatens that "millions of lives are at stake" with a nerve gas, and it's technically correct: it was a roach spray. XD But it seemed threatening enough initially to get the game going]. Probably a given that I loathe the [i]Arkham[/i] games version where he [i]will[/i] outright murder someone to "prove" he's better).
