The Succubus (サキュバス, Sakyubasu?) is a recurring demonic foe in several of the Castlevania games. The male equivalent is known as the Incubus. Succubi are characterized by their ability to seduce their victims, followed by them consuming the life force of these individuals. A Succubus or Incubus is a lower class demon, the exact opposite of the high class vampire. The first Succubus in the series appeared in Castlevania: Symphony of the Night.
Powers and AbilitiesEdit
Succubi or Incubi take on the appearance of very attractive men or women. They possess the ability to create illusions — ranging from taking the appearance of loved ones to creating illusory dream worlds or sensations — to soothe their victims, lulling them into a false sense of security.    The powers of a Succubus or Incubus reside in its claws.  When these claws are damaged or destroyed, it is rendered powerless. 
The Succubus disguises herself as Alucard's mother Lisa in order to deceive him. Throughout the castle, Alucard is able to rest in a coffin in order to restore his health and save the game. One of these save points, located in the Underground Caverns, is different from the rest. If Alucard rests in that particular coffin, the Succubus appears in his nightmare and recreates the moment of Lisa's execution, taking her appearance. The scene ends with Alucard seeing through the illusion and results in an encounter between him and the Succubus. Due to the death of the Succubus in the dream world, her soul is sent wandering for eternity.
She is boss exclusive to Alucard. If Richter visits the room that normally houses the false save point, it is empty save for a single heart that appears upon entrance to the room and floats to the floor.
Rika Fukami is the voice actress of the Succubus in the Japanese version. Barbara Whitlow voices her in the original English dub while Wendee Lee does the voice in Castlevania: The Dracula X Chronicles version of the game.
The Succubus is a palette swap of Lilith. Succubi encountered on either the Top Floor or Chaotic Realm are disguised as Mina Hakuba, and sit as if injured, only to shed their disguise if approached or attacked. In The Arena, a Succubus can be found in the room containing a bathing pool, along with Lilith.
The Succubus' soul is named Death Touch. It's an Enchanted Soul that gives the ability to absorb HP with every hit. This is similar to Alucard's Soul Steal ability from Castlevania: Symphony of the Night. It's also one of the three souls required to reach the true ending. It effectively turns the equipped weapon into a slightly weaker Mourneblade, healing 5 hit points instead of 8, and has the same ability to heal when striking breakable objects, invincible enemies, and enemies which guard the actual hit such as the Dead Crusader and Great Armor.
The Succubus is one of the five guardian monsters who maintain the seal placed on the entrance to the Pagoda of the Misty Moon. Her assigned area is the Ghostly Theatre. After Leon rings the Curtain Time Bell three times, the Succubus appears on the stage disguised as his lover Sara Trantoul. Leon quickly sees through the illusion however, and the Succubus reveals her true form. After she is defeated, the Succubus reveals Rinaldo has a daughter.
The Succubus returns in Aria's sequel: Castlevania: Dawn of Sorrow. She can be found in The Pinnacle, The Cursed Clock Tower, The Demon Guest House, and The Abyss. This time around she disguises as Yoko Belnades. When Soma passes them, they will kick him. Only by attacking Yoko's form will the Succubus reveal her true form. Her soul, Blood Sucker, is now a Bullet Soul that gives you the ability to drink enemy blood which replenishes HP.
The Succubus from Castlevania: Portrait of Ruin looks and behaves exactly like her counterpart from Dawn of Sorrow. She can encountered in the Master's Keep and Burnt Paradise. Due to the two playable characters, Jonathan and Charlotte, being able to switch around at will, the Succubus will say different things when encountered. In case of Jonathan she'll say: "You impudent!", and when playing with Charlotte she'll exclaim: "Filthy cow!".
The Succubus makes her playable debut in the Arcade Mode of Castlevania Puzzle: Encore of the Night.
The Succubus appears in chapter 2: Lord of Unseen Strings, and in chapter 6: Come, Sweet Hour of Death. Her behavior and appearance is the same as from her previous two incarnations in Dawn of Sorrow and Portrait of Ruin. She once again disguises herself as Yoko.
The Succubus is a recurring boss in the Pachislot Akumajō Dracula trilogy.
In the second game, she summons duplicates of herself to hold Trevor down while she steals a kiss and drains his energy. She then unleashes an electrical attack.
She is not shown being destroyed at the end in either game, and instead just pouts in submission.
NECA produced a seven inch tall action figure of the Succubus in their series of Castlevania figures. The figure was released on October 10th, 2007.
A Succubus or Incubus is a demon from European folklore during the medieval ages, which takes the form of an attractive woman or man to seduce the opposite sex. They draw energy from men or women to sustain themselves, often until the point of exhaustion or death of the victim.
The word Succubus is derived from the Latin "succubare", meaning "to lie beneath". The male-form Succubus, or Incubus, draws its name from the Latin "incubare", meaning "to lie upon".
Although the terms Succubus and Incubus have their roots in Latin, entities with the same characteristics have appeared in the Sumerian king list from 2400 B.C. where the father of the hero Gilgamesh is identified as a Lilu, said to be a demon who disturbs and seduces women in their sleep, one of four types of demons to which "the dark maid Lilith" gave birth to.
Succubi and Incubi are often said to be appear man or women in their dreams, though other version of an encounter state it actually sits on the chests of their victims while they sleep. The feeling of pressure on the chest, as well as other sensations, such as hearing voices or hallucinates, has causes the Succubus and Incubus myth to be linked to sleep paralysis.
