–Isabelle, Major Arcana

Isabelle "Izzy" Lightwood is a Shadowhunter of the New York Institute. She is the only daughter of Robert and Maryse Lightwood, is the sister of Alec and Max, and is the adoptive sister of Jace.


Early life

Born the middle child and only daughter of Maryse and Robert Lightwood, Isabelle is the sister of three brothers: the eldest, Alec, the youngest, Max, and is like a sister to Jace Wayland, whom was taken in by the family when they were young.

Raised in the New York Institute, Isabelle trained side-by-side with her older brothers and forged a close bond with them.

New friends

One evening, Jace managed to track a shape-shifting demon's activity to the Pandemonium Club. Isabelle decided to go in disguise, with an all-white outfit and a platinum blonde wig. Once inside, Isabelle distracted the other demons while Jace confronted the one that was peddling mundane blood. She managed to keep them busy until the fight broke out.

When Jace brought Clary Fray to the Institute, Isabelle was with her when the latter woke up. Isabelle even lent her some clothes after Clary's had to be burned.[1] Later, her mundane friend Simon Lewis was also welcomed into the Institute, and Isabelle volunteered to look after him and cooked him breakfast. She also briefed him about the Shadow World and the dangers Valentine Morgenstern and the Circle posed for all of them.

Outside the Silent City, Isabelle, again volunteering to stay with Simon, was flirting with Simon and was alone with him by his van when she heard sounds. She left to investigate, and Simon was gone when she returned. She told the others, and when everyone rushed back to the van, two vampires revealed themselves to be Simon's abductors, negotiating for the Mortal Cup.[2]

To contribute to Simon's rescue, Isabelle contacted the Seelie Meliorn, with whom she maintained a sexual relationship with—a connection she often used to her advantage to gather intel. In this case, Isabelle knew that Meliorn was also sleeping with the vampire Camille Belcourt and that he might be sneaking into the Hotel Dumort to do so. After getting the information she needed, she immediately told Alec and Jace.

She and Alec served as the distraction, going into the entrance she learned from Meliorn, while Jace and Clary went to a more direct route in hopes of finding Simon sooner. She and Alec managed to keep the vampires occupied and beat most of them in battle, and they eventually regrouped with Jace and Clary. Together, they all found Simon with Raphael. Raphael went on to help the group escape.[3]

Mortal Cup

When Isabelle's parents returned from their trip to Idris,[4] Isabelle realized that their family was under the Clave's scrutiny. Deciding to put her family ahead of herself, Isabelle decided to take her mother's words to heart and began a process of self-transformation, beginning by changing her manner of dressing, completely stashing her clothes away, and ending her relationship with Meliorn.[5]

“I think it's fairly clear that the Clave does need help.”

Isabelle is compassionate, warm, charming, and is generally welcoming to new friends. Despite her beauty and kick-ass combat skills, Isabelle is seen to be the moral compass that keeps her brothers Alec and Jace in check in tense situations, though she is also seen to have a bit of a defiant side. Isabelle is not afraid to speak her mind and isn't afraid to break rules, a trait she shares with her adoptive brother Jace. She is able to stand up to higher ranked individuals for what she believes in and fights and argues to get the point across whenever necessary.

She is a skilled seductress who can seduce any man, both Shadowhunter and Downworlder, into either complying with demands or maintaining confidential information. She enchants pretty much anyone who meets her. She is incredibly comfortable with her body; in the past, she wore revealing outfits with no qualms—a way of standing up to her mother's strict rules. During that time, she often acted as the bait or distraction to lure demons.

Isabelle is also equally skilled and deadly in battle, particularly when using her weapon of choice: her whip. Isabelle is feisty, talented, intelligent, and well-educated.

As Maryse and Robert's only daughter, Isabelle is seen as a daddy's girl, having a loving and trusting relationship with her father, while she has a more strained and tense relationship with her mother, who did not approve of Isabelle's decisions and lifestyle. As a result, Isabelle is often maternal toward others, fulfilling a role that was lacking in her life. She is supportive of her brothers, urging them to do what makes them happy. Isabelle is a deeply compassionate person, and she often seeks to comfort those around her.

She is also fiercely loyal to her family and loved ones, willing to let go of her own happiness if it will make things better for them. Despite this, she will fight for what she believes is right even if the odds go against her, and would only cede and make the necessary sacrifice or adjustments when she sees the sense in it and how it would contribute to the greater good.

Skills and abilities

  • Nephilim physiology: Being Nephilim, Isabelle possesses a variety of enhanced physical and mental abilities granted to her by the angel blood of Raziel in her veins and also by the angelic Marks of the Gray Book. This includes enhanced strength, speed, agility, stamina, and coordination, which continue to improve over time and practice.
    • The Sight: As a Shadowhunter, Isabelle is able to easily see through most magical illusions and layers of glamour over reality.
  • Runic magic: Due to the angel blood in their veins, all Shadowhunters are all able to apply runes on their skin without any real danger. These Marks, in turn, give varied effects that serve to benefit the wearer.
    • Use of heavenly weapons: As a Nephilim, Isabelle is also able to perform tasks unique to their species, such as the ability to use and call on the power of angels for their seraph blades, as well as to handle any heavenly weapons or objects with effect, which would normally not work for other species. In particular, these are tools made of adamas and forged by Iron Sisters.
  • Expert hand-to-hand combatant: Isabelle is highly skilled in armed and unarmed combat.
  • Forensic pathology: Isabelle is shown to be skilled in the study of forensic pathology and is referred to by Jace and Alec as the best in New York. She was even able to perform an autopsy on a strange new form of Forsaken and was able to successfully deduce what made it special.
  • Bilingual: Isabelle fluently speaks English and is shown to also speak Spanish.

  • Her casting press release described her as an exotic-looking, model-beautiful Shadowhunter who, as an expert with her whip, is as lethal as she is attractive; is a trained fighter who can kick-ass in high-heels; and whose one weakness is her choice in men—always going for the bad boy.[6]
