"The stones of power shall be mine!" - Margaret Isobel Theroux, Spell

Countess Margaret Isobel Thoreaux, more commonly called Isobel, was an infamous and aristocrat witch of France who lived in the early 17th century, as well as the ancestress of Lana Lang. She has been referred to as Countess, Countess Theroux and more commonly, Isobel. She was from the village Castelnau-de-Montmiral. Isobel was shown to be highly accomplished in both witchcraft and martial arts.

Lana purchased the Countess' spell book on eBay and once she touched the symbol, Isobel was reborn in her body.

Powers and Abilities


Isobel and her friends cast a spell at Clark's party.

As a witch, Isobel had considerable magic capabilities at her disposal. Due to a spell book filled with numerous spells, Isobel had a vast repertoire of various supernatural powers, of which being stronger than her other spells. Appearing to be a signature of hers, Isobel often cast a violet array of energy, from her fingertips, which proved to be devastating and chaotic. This attack destroyed anything it hit, but when it hit Clark, he was only stunned but was strong enough to survive. She also had the power to ignite a target in a violet flame and have the fire glow eerily brighter than normal. She also had a mind-control like power which allowed her extract information from someone by merely being close to them. Isobel also displayed the ability to tell if someone was a virgin just by looking at a pluck of their hair, noting Lana has been a "good little girl" and Lois' hair was not viable as she needed two virgins' hair to revive her witch friends.

It seems that her power was far greater than those of her two cohorts, Brianna and Madeline, who were only able to muster a handful of spells, like mild illusions and energy blasts, while Isobel seemed to have a massive reservoir of powers possibly because of her superior experience in the magical arts. They both appeared to be very adept at telekinesis, such as when they threw a wheel and various farm tools at Clark, which he was able to block or deflect with his Heat vision, respectively. Neither of them had the ability to defy death alone, requiring Isobel to resurrect them: it was also her who drained Clark's Kryptonian powers, using herself as a conduit to siphon away all of his abilities. This leads to the assumption that Isobel was the greatest of the three, wielding more power than any other non-alien. It is unknown if she was superior, inferior, or equal compared to Zatanna.

While in possession of Lana Lang, Isobel used other spells, such as when she enchanted two swords during her battle against Clark. Due to the hue at the tips of the blades, the weapons could harm him. She was also able to levitate and although rarely displayed, she could move at alarming speeds, though not nearly as fast as speedsters. As a fully fledged witch, she could create rifts or minor tremors in the Earth.

She could also place others under a form of temporal stasis (which she does to Lex before she enchants him to play the piano).

  • Super strength: She possessed impressive superhuman strength that is somewhat above the average of a typical human, though still far inferior to any other superhuman being, including Clark. Isobel, through Lana, was able to activate this ability, but seemed to be suppressed at first, as shown in Sacred, when she burst her bonds when she took possession of Lana Lang in China when Lana was about to be tortured by Chinese soldiers. She demonstrated it again when she possessed Lana for the last time when she easily overpowered and stabbed Genevieve Teague, a much larger woman, with the Air Stone when Teague attempted to kill Lana.
  • Invulnerability - She possessed somewhat of a high durability threshold. While in China, when Lana was tortured by Chinese soldiers with and Isobel took possession of Lana again, she also showed some level of invulnerability to electric shock. Isobel came back as Lana was being electrocuted by her captors: that electrocution was unsuccessfully used on Isobel and she stated that she would not let any harm come to Lana, the body she inhabited.
  • Magical Senses - Isobel possessed an awareness of anything magical, being able to detect their auras. She was able to sense Clark's powers and determine that he was not magical.
  • Teleportation - Isobel was able to teleport vast distances with naught but a word. When the stone of air was on the ground and Clark ran at super speed to grab it, Isobel teleported and got to it first.
  • Telekinesis - By utilizing spells from her book, Isobel could influence the movement of objects, being able to lift, throw, or manipulate objects and people with her sheer force of will.
  • Energy Blasts: By just a swift movement of her arm she was able to project powerful bursts of energy which could knock out any person who came into contact with them, usually knocking them back. This is used when she breaks out of the prison chair, knocking out the guards and twice against Clark, knocking him out both times. Thus showing how incredibly strong it was.


She does appear, however, to have one weakness, which ironically is the very thing she sought. She seemed to be unable to touch the Stones of Power with her bare skin without it burning her. Originally she is unaware of this and is stunned when the Crystal of Fire burns her and is repelled from her. She later takes precautions against this by wrapping the Crystal of Air in a red cloth, so as to prevent it from touching her skin.


Spellws 016

Isobel is burned at the stake.

Isobel was recruited by Duchess Gertrude to find the stones. Isobel went to a tent with a mystic and saw a Kryptonian in the globe, who told her that if she got the stones they could rule together. She walked out thinking she herself could rule Earth one day. (Smallville Magazine, "Legend")

However, Isobel betrayed the Duchess in the end and stole her map to the Crystal of Air, so she could have it to herself.

Madeline Evans and Brianna Withridge were the Countess's comrades and they helped Isobel search for the Stones of Power. The Duchess accused them of being witches they were captured by the townspeople and were sentenced to burn at the stake for practicing witchcraft, although it turned out Gertrude was a witch also. Isobel lost her spell book and was brought to the courtyard to be burned along with Madeline and Brianna. Before she was burned, Isobel spat blood which intertwined with the book's symbol and added a word giving her a chance of resurrection. The Mark of Transference appeared on her skin, which would enable her to possess Lana's body. As the Countess and her companions burned, she prophesied that her heir would awaken her and that she would find the stones and have vengeance. According to Genevieve Teague, the Countess also vowed to kill each of Gertrude's heirs, therefore destroying the entire future of Duchess Gertrude's family line when Isobel rose again.

Isobel apparently had at least one child before she was executed, as Lana was her descendant.

Season Four


Lana changes after touching the cursed page.

Centuries later, Isobel's tomb was placed in a church in Paris by the grandmother of Genevieve Teague, who used her son to orchestrate a visit by Lana to the tomb. When Lana did a rubbing of the Countess' tomb, she was blasted with a beam of light that branded her with the Mark of Transference. She woke up twelve hours later in her bedroom, with no memory of what happened. This drove her to return to Smallville when she saw the symbol in the Kawatche Caves in some online pictures. She hoped that by returning home, she could learn more about the Mark and the Countess. Jason soon followed.


Isobel and her companions are reborn.

Lana became possessed by the Countess Theroux when she touched the spell book she had purchased on eBay. Isobel made a potion to restore the spirits of her followers. Brianna's spirit was transferred into the body of Lois Lane and Madeline's into Chloe Sullivan. She then stole the hidden map in the Russian Manuscript at the Luthor Mansion and placed a spell on Lex Luthor to play the piano indefinitely. Isobel and her comrades infiltrated a party thrown by Clark Kent and bewitched everyone, including Clark, to start losing their inhibitions and for all the boys to take their shirts off and dance in their boxer shorts. The next morning, having regained consciousness and learned what had happened to Lex, Clark confronted Isobel just as she had reacquired her old spell book from Jason, forcing him to rescue Jason while she escaped, leaving him a message to meet in the barn at midnight.


The three witches take Clark's powers.

In the subsequent confrontation, Clark's invulnerability and heat vision allowed him to withstand the witches' initial attacks (although they assumed that he was a sorcerer rather than an alien), but they nevertheless managed to get the upper hand, stripping Clark of his powers and leaving to open the hidden chamber in the Kawatche Caves after realizing that he knew where one of the stones was hidden. When Clark arrived to stop them, having been released by Jason, Isobel grabbed the Crystal of Fire, only to scream out in pain as the stone protected itself from her. Clark grabbed the stone, which restored his powers. Although Isobel threatened to remove his powers again, he swiftly destroyed the spell book with his heat vision, causing Lana, Chloe and Lois to revert to normal.

Isobel in a confrontation with Clark.

Isobel emerged once again after Lana was tortured by Chinese officers. She broke free from the Chinese officers and revealed that the map is the key to one of the Crystals of Knowledge. Isobel knocked Clark out and went to the location of the Crystal. Isobel unearthed a horse statue holding the stone. When she broke it, it gave off the piercing buzz to Clark: he followed its origin which led him to Isobel and the Crystal. Isobel fought Clark with magically-powered Chinese weapons. She wounded Clark, who put up a fight against the magically-skilled Isobel. Clark managed to defeat her and get the stone away from her but when Isobel touched the stone together with Clark, there was an explosion. The effects of the explosion seemed to send Isobel back into hiatus and the stone disappeared.


Isobel kills Genevieve.

Isobel resurfaced for the last time when Lana was being strangled by Genevieve Teague and used the Air Stone to stab Genevieve in the heart. Once Isobel had exacted her revenge on Duchess Gertrude, she freed herself from Lana and Isobel's spirit could finally rest. The Mark of Transference was removed.



  • Kristin Kreuk is of Dutch and Chinese descent. However, Lana's ethnicity has never been mentioned on the show, besides the fact that Threroux was French.
