Strengths:
Can turn into a full wolf at will.
Stronger and faster.
Greater sight, smell, and hearing.

Weaknesses:
Silver is poisonous.
Can be killed by beheading, stab in the heart, fire, and too much silver interaction.
Newly turned can go insane if they are not helped by others when they turn into a wolf.

How one is turned:
A bite from a lycan in wolf form has a chance to turn the human victim, especially if the bite goes into one of their veins.

How to cure a Lycan:
The one who needs to be cured can only be if they have never drank the blood of humans. If they haven't, they need to drink liquid silver and a mix of a lycan’s blood who's over a 1000-years old.

Rand's Notes:
Lycanthropes, not werewolves, remember that. Lycans can morph at will, werewolves can't and don't have control over their wolf form. It's as simple as that and still some people mix it up. It really bugs me. Anyway Lycans have a relation to werewolves and that's the simple silver. Cut them deep and they'll be crying for hours. Even poking these guys with it makes them visibly poisoned. Having a silver rod or dagger at all times is a pretty safe precaution and good tester against them.

Their wolf form can be of various wolves, but so far I haven't seen any that were close to house dogs. The types and colors can vary, but their eye color and wounds stays the same. Pretty much the only two things that you can connect between the two forms. The weaknesses don't change at all when they change, but their sense to hunt is more driven when they’re in their wolf form.

Killing a lycan is a bit easier than other supernatural. Decapitation, fire, stab in the heart, and silver will do the job. If you have a silver blade, the most ideal solution is to stab them in the heart. It’s the easiest way to take them down and out for the count.

Strengths:
Night vision.
Enhanced athletics.
Enhanced senses.
Feeding of blood from humans enhances powers.
A power of your choice. If you can't come up with one ask me for suggestions.

Weaknesses:
Can go out in the day but get really nasty sunburns.
Can be killed by beheading, stab through the heart, and fire.
Their blood bubbles when cut by steel but it can't kill them.
Feeding off of animals will eventually turn them insane.

How one is turned:
A vampire can turn a human by injecting their own blood into them. While usually take a day before the process is complete.

How to cure vampirism:
The one who needs to be cured can only be if they have never drank any blood at all. After that, they need to drink a mixture of a vampire who is over 1000-years old and dead man's blood. The process painfully takes 24 hours.

Rand's Notes:
Vampires, probably the most common supernatural that this world has. There have always been constant variations on what people thought they were like, then there was the tie in with churches and crosses somehow became a vampire's weakness. I guess they depicted vampires as a spawn of Satin? No idea, I didn't go much into it studying how people were wrong. Anyhow, there's no relation to that whatsoever. Really the only similarity are the fangs and murdering humans.

On basic description of vampires, there's not much. It's just the simple two fangs that are the canine teeth that they can switch back and forth at will. Steel seems to be the only way to identify them when they're trying to hide. When they're cut by it, the blood pours out and sizzles like it's being boiled. It's pretty effective, but the problem is that you need to get close and slice them with a knife, which becomes a really awkward situation when you're wrong. Vampires are mostly nocturnal, but there's no harsh effects on them going out in the sun, all they really need is some sunscreen.

Getting into a fight with these things are quite nasty, especially if you're alone. For starters, they're stronger in both athletics and senses than the normal human, and they have pretty good nightvision to top it off. Steel is the most effective weapon against them as it is the only element that has a unique effect on them. Don't ask me why, it's some scientific reason, like their body doesn't agree with it like ours does with poisons but on a more radical rate. Beheading them is an effective method to making sure they're dead, but shooting or stabbing them in the heart does the job as well. The problem with the latter is that it sometimes doesn't kill them, so what I recommend is beheading them afterwards. Fire works but is probably the worst method for doing so. They can burn to death but that takes way too long. I remember pouring gasoline in a room with a tied down vampire then setting it aflame since I had no other weapons. I sat outside the room for about three hours when he finally stopped screaming.

Strengths:
Can seduce males with persuasive powers.
Rapid reactions.
After a period of time with a male, they indoctrinate him to make him a fanatic servant. Having the male make the bond heightens the power over him.
Powerful regeneration.

Weaknesses:
All their power is in their voice.
Have no real power on those who aren't attracted by their gender.
Any males they brainwash can be freed by the controller dying or the male not having contact with their controller for 24 hours.
Can only be killed by decapitation.
Their blood bubbles when cut by bronze but it can't kill them.

Rand's Notes:
Right. Succubi. I don't like them. Sure they're not as physically strong as their spin-offs like empousai and sirens, but I personally hate them the most. Their reputation is also the best out of the two, being "the devil's whores" or whatever people also name them. Really, that's a lie and they're not demons, but some people still think that. Really, I'm not sure how succubi came into existence, but it was probably like lycans and vamps where there was some genetic difference of the alpha and that alpha made more of her kind. That's all I got for ya on that.

Succubi are known for their persuasive powers they have over males. It gets really annoying having to deal with these things, especially when they already have servants ready to give their lives for her. Going solo when you're male like me against a succubus is basically suicide, because you'll be dropping your weapon and roll over like a dog for her. Headphones can somewhat block their voice out, but they can get through that sometimes as well unlike their spin-offs.

I don’t like proudly showing off the fact that I have personal experience of being a succubus’s slave but I find it necessary to put it in here. Having this experience also heightens the fact that dealing with a succubus is near impossible when alone, and they are really good at disguising themselves. Most succubi work slowly and like to draw their victims in as what happened to me. When it gets to the point that the intended victim is so taken in and influenced by them the succubus seals the deal by initiating with some kind of physical attraction, the most basic of them simply kissing and sometimes intercourse. Usually they like the victim to do this initiation since that makes their control much harder to get rid of. After that, the male is theirs to command, and that boy will do all they can do to help their master. All that’s in their mind is to help her, and their own memories will all be vanity.

Removing a victim from a succubus’s influence is incredibly hard. Not only will the victim violently rebel, but the succubus is also very bitter over losing one of her boys. There’s really only two ways to cut connection. The first is to remove contact between the two for an extended period of time. For ones that have been in her service for a while this may take up to a week so make sure there’s no escape for them. Of course, the other way to split the connection is to kill the succubus herself, but that leads to another problem.

I'd like to say their most annoying aspect is how hard it is to kill them. Bleeding out, starvation, heart stabbed, fire, drowning, suffocation- none of these things works. Sure it hurts them but none of that stuff will kill them, and their powerful regeneration just makes it go away within a couple days. The only way I've really discovered so far on the sure way is decapitation. Yep, that's it, and it gets very hard because you can't decapitate something with a gun. You have to get really close and that's how they like it. This is why I just have Sarah do it most of the time for me while I blast Metallica through my headphones outside of the building.

Strengths:
Can seduce humans with their singing voice.
Rapid reactions.
After a period of time with a human, they can indoctrinate him/her to have him/her become a fanatic servant.
Sirens can breathe underwater indefinitely and have minimal water powers.

Weaknesses:
All their power is in their voice.
Have no real power on those who don't find their gender attractive.
Any human they brainwash can be freed by the controller dying or the human not having contact with their controller for 24 hours.
Can be killed through beheading, fire, stab through the heart, starvation.
Their blood bubbles when cut by iron but it can't kill them.

Rand's Notes:
Siren origins are varied. The most common form are the ones I call the spin-offs of succubi, but of course there's the ancient "pure" race of them. Those ones are weird and creep me out, but they're extinct so I don't have to worry about them!

Sirens are almost a different matter when it comes to their powers. Sure, they also have persuasive-like powers but with them it's in their singing. Cut their singing before they have you within their grasp, and you're fine, half the time. They can really easily start singing again, and then it's back to square one. But cut their voice or blast on your headphones during that time, then you're good. If you don't, same result as becoming a succubi's slave, complete dominance over your mind. Fortunately, they're much easier to kill. Stabbing, bleeding out, decapitation, fire, they all work quite well, except obviously you can't drown them. Putting them in water is the probably worst idea you can have. Not only can they breath forever in it, but some have water powers and several others can turn their legs into a "mermaid tail". And no, mermaids don't exist, and if you think you've ever encountered one, run as soon as she begins singing.

While these are ones I have fully written out, you can pick one that's not here!
