Jyster (humanus mimicus)
Type: Humanoid
Threat: Minimal-Extreme
Jysters are one of the earliest known monsters to man. They are most noted for creating the circus that we all know and love today. What makes them so interesting is their ability to mimic actions of others to near perfection. This allows younger generations to easily catch on what they are supposed to do when they need to relieve their older counterparts of their duties.
This mimic ability also has a practical use when it come to self-defense. A Jyster is able to repeat any attack an enemy performs after seeing it once, but there are limitations the mimic ability has. The mimic ability cannot replicate attacks that the Jyster cannot perform on its own, say a dragon's fire breath for an example.
Other than its mimic ability, the Jyster has some kind of spiritual energy within itself. Said energy can manifest into a physical form, but said form is transparent and nigh-invisible. The Jysters are able to form this energy into objects which they can use for defense. Their way of summoning said objects can be akin to a mime performance. Some of their objects range from rapiers, to hammers, and to the infamous Mime Wall. I have heard that the objects can be slightly altered to better suit the Jyster, but that is pure speculation. An odd thing I've found out is that Jysters cannot mimic other Jysters' summoning, implying that this summoning must be learned on one's own accord. A side note to add is that Jysters can only summon non-ranged objects, like they cannot summon a bow.
Aside from their inhuman speed and strength, Jysters are unnaturally durable. In my times of recording this species, I have seen Jysters get into seemingly precarious situations, but only to defy death by coming out of it with little to no injuries. Burns, falls, crushes, cuts...they don't seem to be affected at all. I wonder if they can die another way than natural causes...?
Unlike most humanoid monsters, Jysters are not easily identifiable and cannot be easily distinguished from a normal human at a glance. What makes them distinguishable is their behavior. A Jyster's normal behavior is considered to be...insane when compared to our normal behavior. However, I find that the more unhinged a Jyster becomes, the more powerful it gets.
Besides their psychotic nature, Jysters are typically friendly and more than not mischievous to a certain degree, making them one of the few monsters which aren't a direct threat to humans...that is, if you don't anger one. Like an animal defending its own, a Jyster will not cease attacking until the threat is eliminated, however their abilities mentioned above make them extremely hard to stop once they are triggered.
Luckily for humanity, Jysters are hard to anger, though I would be extra kind to one if you've ever meet one.
