Mercy Mackenzie, Max and Ruby's neighbor, is a succubus. This means she lives off the life force of others, using seduction to gain access to it. So does that mean Mercy kills the people she's intimate with?
While killing ones meal is the typical behavior for a succubus, Mercy chooses not to. This is one of the reasons she's able to live in Leystone and is seen by RCSI as a law-abiding citizen. She follows the rules set up by the agency and limits how much life force she takes from each individual.
She does take a bit each time she's intimate with another, but the amount is low. At most it makes her current partner feel drowsy and a little euphoric. Of course, the euphoria could be from everything else going on at the time. The next morning the person is refreshed and not affected at all, yet Mercy still had her meal and a bit of fun to boot.
While it rarely happens Mercy has occasionally gotten carried away in the moment, shall we say, and taken a little too much at once. While it's still not enough to kill, this can lead to her current partner feeling as if they are under the influence of LSD. In these cases Mercy has been known to rush the person to RCSI Headquarters and straight to the Medical Bay. This is done despite the fact that admitting to having taken more than the regulated amount in one sitting will result in her having to pay a fine and possibly receiving a mark on her record.
Draining a person completely and killing them would mean that Mercy would need to feed less often, maybe once every few months instead of once or twice a week. But she doesn’t mind. Mercy actually enjoys being around others and making them feel good, whether that be emotionally or physically.
Mercy also enjoys baking and likes to infuse her creations with her own special brand of magic.
While she can't induce people to fall in love, her magic can create feelings of lust in others, especially if there's a bit of emotion already there, lurking under the surface. While this may sound hazardous to youngsters, she is careful to keep to RCSI's regulations. The end result, minors are not affected by Mercy's spells, potions, influence, or food.
Mercy's proof that a succubus can live among mortals without causing any harm. She's a sweet woman who wants to enjoy life and find her true love. Unfortunately, in her mind, her true love is every man - and more than a few women - who crosses her path.
