Name: Koudelka Iasant, also known as "Zslato", "Mysterious Voice", "Angel", and "Witch of the Darkness Flames"

Origin: Koudelka/Shadow Hearts

Gender: Female

Classification: Human Gypsy/Psychic/Witch/Channeler, Key of Darkness (A being born every century, who acts as a conduit/embodiment of sorts to dark/negative magic)

Age: 19 in Koudelka, 20 in Koudelka Manga, 34-35 in Shadow Hearts

Powers and Abilities: Superhuman strength, speed, durability, and endurance, enhanced senses, adept at wielding various weapons, magic, telekinesis (disintegrated a giant snake demon spirit with her TK), telepathy, mind manipulation/hypnosis (made vicious hunting dogs docile with her pendant, tried to attempt to do it without when she had amnesia, also has the power to project her consciousness into less sophisticated creatures such as rats and directly control their bodies as if they were her own), dowsing/psychometry (was able to see the ship crash by touching the painting in the Koudelka game, and was able to read Dr Horn’s mind/soul by doing a psychometric reading in the manga), clairvoyance/precognition (predicted her father’s death when she was nine, the exact time and place, and how it was going to happen), elemental manipulation (of the fire, ice, water, earth, wind, and lightning variety), healing (low-mid via powerscaling [Albert Simon can heal/regenerate his left eye at the beginning of SH1], in a form of Heal [she used her healing to the point of bringing back Edward from near death]), resurrection (in a form of Revive), barrier creation (in a form of Reflect and her pendant), can enhance herself and her allies' stats (in a form of Fortify STR, Fortify VIT, Fortify DEX, Fortify AGI, Fortify PIE, Fortify INT, Fortify MND, and Fortify LUC), can debuff enemies stats (in a form of Defortify STR, Defortify VIT, Defortify DEX, Defortify AGI, Defortify PIE, Defortify INT, Defortify MND, and Defortify LUC), energy manipulation and transference, exorcism, spiritual awareness, can track anyone down with a touch via spiritual connection, able to allow herself to channel the spirits of the dead, and allow them to possess her body, has some resistance to possession, and resistance to a gas that induces sleep, immunity/resistance to fire element, has incredible willpower | Supreme arcane knowledge, reality warping, soul manipulation/absorption, can grant immortality (type 1, 2 and 7 [Dogol survived being pummeled by The Author, and was still alive as an eyeball]), can summon/control the Author (like a Stand)
Weaknesses: Nothing notable | She can risk becoming possessed by The Author (however Koudelka further hypnotizes herself locking away the Author's power and her knowledge of the Émigré Document unless specifically invoked, as prolonged exposure would likely leave her insane)

Destructive Capacity: Planet level, likely much higher (defeated the Gargoyle who's spiritual energy made Koudelka tremble in fear, and was able to hold her own against Elaine) | Solar system level, likely much higher (she is the opposite to Alice who is the Key of Light [Alice’s power was capable of summoning Seraphic Radiance, while Koudelka’s power was capable of summoning Meta-God], is on par with Roger Bacon, Albert Simon and Rasputin. Even her son Halley can use his uncontrolled power to create blackholes) | Solar system level, likely universe level (The Author’s power was affecting the entire world, creating tidal waves and thunderstorms in the Koudelka Manga sequel. When Koudelka awoke from her hypnotic trance in SH1 she displayed a tremendous power, one that even gave Simon a sense of awe, a significant feat since up until then nothing had seemed on par with Albert's powers [Albert even refers to Koudelka as "the Witch of the Dark Flames", likely a reference to the Author's power])

Range: Planetary (while being imprisoned in England, she has been in contact with Yuri in China with her telepathy and has been doing so ever since) 

Speed: MFTL+ (should be comparable to her son, and to the majority of the SH1 roster; characters that have battled a being that was above 200m c, you even have lesser enemies that can travel and attack at lightspeed)

Durability: Planet level, likely much higher (survived the defeat of Elaine) | Solar system level, likely much higher | Solar system level, likely universe level (tanked Albert Simon’s attack in SH1 that came from his demon contract Amon)

Lifting Strength: Superhuman | Possibly higher

Striking Strength: Class XJ | Class XPJ | Possibly higher

Stamina: Large

Standard Equipment: Her pendant (It was used to repel Elaine’s corrosive acid blast spit with a forcefield that is capable of melting Koudelka, Edward and James down to a skeleton in the Bad Ending, it can also be used for hypnotizing, as Koudelka had hypnotized herself years ago to respond to the presence of the pendant if she was ever deep in a trance or under a spirit's possession) and a knife, but she can also wield a variety of other different weapons ranging from knuckles, swords, clubs, axes, spears, guns and crossbows
Intelligence: Pretty intelligent, very observant and good at smelling out poison in Ogden's and Bessy's soup due to her knowledge of herbalism, highly skilled combatant and magic user, has experience fighting demons/monsters/ghosts/anything supernatural, is good at performing exorcism on spirits, is skilled in alchemy, and also has the Author in her body absorbing the full knowledge of the Émigré Document
