Incubus and Succubus

Characteristics
These demons are generally very attractive or pick vessels that are. There are no real outside traits they always have that would seperate them from anyone else.

Special Abilities and Distinguishing Features
The demons are essentially revved up humans. They're faster, stronger, very clever and much harder to kill.

This set of demons is known for having red eyes that they can hide. If they are half it's a little bit more difficult to do and it is perfected over time. They are more prone to show up in times when the demon is aroused or in a sexual situation.

These demons feed on sexual energy. The effects can be very strong or weak depending on the demon and the victim. A human partner would be more at risk to be drained of energy and over time maybe even be at risk of death. More powerful races however wouldn't feel the effects as strongly so some demods choose their partners based on this idea. They can also feed off the sexual energy of other just in a place but it's not as strong. However they can take a more passive role and cause a sort of aphrodisiac like effect in a place and not partake in any of it themselves. This is another thing that gets more powerful over time.

They can easily get at that part of people and are masters of seduction. Most use it for more than just getting someone into bed.

The pure demons of this variety can take a male and female form. The two forms generally resemble each other. The demon also normally favors one or the other and spend more time in that form.

Life Cycle
Demons can live for a very long time, some say they are immortal. They are easier to kill than Immortals, being able to die in more ways.

Cultural Description
These demons are spread out all over so there's no specific culture but there are some unifying traits. They can normally be found in positions of power and in a place where sexual acts run rampant. They also climb ladders in businesses quite well. For instance a good portion of the McNamaras worked in advertising for a very long time. Some other common places they might prowl or be involved in are bars, strip clubs, brothels and night clubs.

McNamaras
The big line of Incubi and Succubi in play are the McNamaras. Most of this family are only half demon. The head of the family is Astrid. He's a full fledged. Despite his general lack of morals he prizes family and will viciously protect his own if he is aware of them. He has taken a personal interest in most of the McNamaras and has even trained some of them personally to hunt. He also tends to send them large sums of money on a normal bases even if he doesn't see them often.

The family name has been attached to an advertising firm for most of history and they do very well for themselves. Astrid attempts to keep the family from taking this for granted and tells them to succeed for themselves but of course this doesn't always get through to them.

In World's End Astrid lives in a skyscraper in the NYC dome and keeps some of the floors empty for family members in case they suddenly need somewhere to stay.

Despite his own lack of a moral compass he doesn't encourage the family to take lives. He lets them do what they want. With his family he's gentle. Everywhere else he can be vicious.
