In most fantasy works with multiple species, we tend to have racial niches. Traditionally in fantasy, we have Elves, Dwarves, Orcs and humans as the primary races, with elves often divided into high, dark and wood varieties, but we often have many other variations. This is similarly true in sci-fi worlds, but it's easier to focus on fantasy for the sake of their conversation because 1. that's what I'm thinking about now, and 2. there's more traditional races there thanks to Tolkein's taking over of the genre.
In fantasy realms, elves are often the magical, long-lived, intelligent species, with high elves being more moral and full of themselves, dark elves being sadistic and wood elves being hippy fucks. Orcs are dim-witted, strong, tribalistic warriors. Dwarves are honorable, mining, bearded blacksmiths. The races are always clearly defined in certain roles, and while they might have subversions or characters breaking out of these roles, the races still have generalized characteristics.
However, humans for the most part don't have any traits. They tend to be the everyman, the jack of all trades or something equally boring. They're pretty much the blandest of all races, despite the fact they're usually the most populous because despite being outpaced by every other species, tend to be the most successful.
So, I was looking for your guys ideas on traits that would be unique to humans, or at least areas in which humans would be advantageous, like elves' magic or dwarves' blacksmithing, or anything, really. Sometimes they get bullshit ones like "the best leaders" or "the most heroic" or bland, generic goodness. But fuck that, never mind. I think it'd be really cool to try break the mold of humans being so bland, so I'd love any ideas you have.
Here's two I was thinking of, to get the ball rolling or to more likely be the only suggestions in this thread when no one responds...
-Humans as breeders: Normally in fantasy, humans have relatively short lifespans compared to other creatures. Humans are also less stern and shrouded in honor than dwarves and elves, and possibly orcs, depending on whether they're the savage warriors or the honorable tribal warriors. Either way, humans having short lives and just fucking way more like rabbits would suit them as a trait, would explain why there's so many of them in most fantasy works, and would give them an edge in battle, namely throwing men.
-Humans as dominators of animals: With elves being magical, orcs traditional warriors, dwarves the tech edge, calvary in terms of war often gets left out as a racialized thing. I can't think of any examples of traditional fantasy races from ogres to lizardmen to kobolds to whatever else. Thus, it seems like a reasonable spot for humans to have. Humans as masters of animals. The more monstrous races are too violent to tame creatures while the higher races would think of themselves as above dealing with beasts, humans could be masters of animals, with the power to bind them to their will. This could extend to other animals, with humans mastering the use of war dogs, other beasts of battle and any animals. The other races could have tame animals like other races have magics, but it'd be man's specialty.
Annyhow, those are my ideas, let's hear yours. This is primarily geared towards fantasy, but ideas for unique traits for humans in sci-fi would also be very interesting. Technically, humans could have ANY unique trait, but I'm looking for ones that would more easily fit with the generic fantasy world that's usually dealt with.
