Tiberius Blackthorn is a Shadowhunter from the Los Angeles Institute. He is the son of Andrew Blackthorn and brother to six siblings.


Early life

Tiberius was born to Andrew and Eleanor Blackthorn in 1997, the fifth of seven children, having been born a few minutes after his twin sister, Livia.[1][2][3][4]

In November 2007, Ty visited the New York Institute with his family. According to Jules, he and Livvy were eating wax, much to the exasperation of their older sister, Helen.

Dark War

Shortly after, the Blackthorns fell victim to one of Sebastian's plots. Sebastian attacked the Institute, Turning those they could into Endarkened to add to his army. Ty and the other children were able to escape to Idris through a Portal opened by the Clave for them, though their father was Turned and their half-brother Mark was captured. Shortly after they arrived, the children were interrogated with the Mortal Sword, which is a very painful process.

During the battle during which the Endarkened and Seelie faeries on Sebastian's side attacked Idris, the children were escorted by Brother Zachariah and Helen to the Accords Hall where they hid for the rest of the battle. Eventually, the Wild Hunt was able to get through the defenses and paved the way for the Endarkened to enter the Hall. Among the Endarkened was their father who then approached Ty; Ty was very trusting and did not attempt to move away. He could have hurt him so, in a panic, Jules killed their father. Ty witnessed the act firsthand and angrily hit Julian before Livvy stopped him, telling him that Jules had to do it.

After the war, it was decided that Helen would be exiled to Wrangel Island and Mark left to the Hunt. This left the children with no legal guardian, and Mrs. Sedgewick suggested that the children could be sent to the Shadowhunter Academy or to separate Institutes, until Jia Penhallow introduced Arthur Blackthorn, the children's uncle, as their guardian and the new head of the Los Angeles Institute. When Helen bid her goodbyes to Julian, she asked him to pay special attention to Ty.[5]

When Arthur introduced himself upon his arrival at the Institute, Ty did not look him in the eye. Livvy explained that Ty did not mean to be rude, Arthur has since dismissed Ty as weird and different.[6]

Cold Peace

In 2009, Ty was briefly reunited with his older half-sister Helen in a rare instance the Clave allowed Helen to return to Idris for her wedding to Aline Penhallow.[7]

At one point, Ty decided that he wanted to go to the Scholomance and become a Centurion, much to the dismay of his twin sister Livvy, who wanted to be his parabatai, and Julian, who feared what the Clave and the cruel Scholomance might do to him.

In the summer of 2012, Ty and his siblings visited their great-aunt Marjorie in England. He hid in the barn throughout the visit to avoid having to do chores and train. Shortly after they returned to Los Angeles, a party of faeries arrived and offered to return their brother Mark in exchange for help finding the culprit behind the recent murders.

Eager to get his brother back and prove his worth, he and Livvy actively helped in the investigation. Wanting to help out in the field, Ty once hid in the car Emma and Julian took to the home of Johnny Rook; when he noticed movement in the basement, he snuck into Rook's house and attacked the person lurking in the basement, whom they later discovered was Rook's son, Kit. Ty held a knife to Kit's throat until Johnny forced them to leave. Julian became furious at Ty for endangering himself, though Ty didn't understand the reason for Julian's anger.

Ty later accompanied his family to rescue Tavvy from the Guardian, who had been their family friend Malcolm Fade all along. When the death of Malcolm resulted in the death of Johnny Rook and thus Kit becoming orphaned, Kit was brought to the Institute where it was proven that he was a Shadowhunter. Ty sat and waited outside Kit's room while the latter came to terms with everything he just experienced and learned.

Personality and traits

Ty has a brilliant mind and has his own way of expressing his thoughts; he sees the world differently, and while this is known among mundanes as autism, it is not accepted in Shadowhunter society and Ty is seen by some as odd or strange. Ty tends to keep to himself, and his inclination to do something may depend on his mood at times. He is also extremely stubborn.[6]

He wants to be a detective and is an avid fan of Sir Arthur Conan Doyle's Sherlock Holmes and other crime stories in general.

Ty also loves animals. Though he likes many species, he particularly likes those with wings, such as butterflies, moths, and is especially fond of bees. Ty takes pride in being able to draw insects realistically.[8] He spends a lot of his time outside to bother animals like lizards and squirrels.[6] When he was young, he even hid animals in his room—such as bees and once a rattle-snake—claiming to be studying them and being their friends, which he often got in trouble for, and was also practically inseparable from the stuffed bee Jules had gotten him.[5]

Ty's room is neat and organized. His books were sorted according to color, with his favorite colors near his bed and the ones he didn't like were hidden from view in nooks and spaces. Though not arranged in a typical way, Ty would know every book's location by heart. His most loved books, the Sherlock Holmes stories, sit on his bedside table along with a collection of small toys that Julian made for him when he was younger to help him calm down and focus.

Ty's twin sister wants to become his parabatai, but he is uninterested because he wants to go to the Scholomance—an ambition which Diana and Julian do not approve of, because they fear that the Scholomance will not be accepting of Ty's differences and gifts.[6]

Physical description

Tiberius, unlike his siblings, has dark black hair and gray eyes, as opposed to the family's trademark brown hair and blue-green eyes. He and his twin sister Livvy were born with gray eyes, though hers had changed to blue-green since, though they both still have long lashes and cupid's bow lips. Julian puts down Ty's ability to be different to sheer stubbornness. Ty is apparently also quite skinny, and is also seen as attractive by those around him.


Tiberius and Livvy are practically inseparable. They are fiercely protective of and would do anything for each other. Livvy is one of the few exceptions to Ty's reservations; that in one way or another, Ty almost always gives Livvy what she wants... except becoming parabatai.

Ty cares for Julian, who practically raised him, very much. Though he rarely show Julian much affection, he is visibly upset when Jules' life seems at risk. Julian goes out of his way to make Ty as comfortable as possible, showing that they have a special bond. Growing up, Jules concocted ways to accommodate the way Ty's mind works and never made him feel less or any different from others.

Skills and abilities

Ty isn't much for fighting, specifically because he had no interest in it. When the need arises however, and when he feels like it, Ty would pick up a weapon. He is actually quite skilled at throwing knives,[6] which is his primary favored weapon,[9] along with the quarterstaff.[8]

Following the family tradition of Greek and Latin names, his namesake is that of the Roman emperor Tiberius who was married to Livia, whom Andrew named his twin sister after, a deliberate instance which Andrew finds funny.[10]


  • While Ty's features do not exactly resemble his siblings', he does look like their Blackthorn ancestors,[6] such as Jesse and Rupert.[11][12]
  • Ty is partly based on Cassandra Clare's autistic step-brother.[13][14]
  • Ty favors classical music since classical music is an anxiety reducer and he often uses headphones to block out noise that might cause disregulation/anxiety. Also he generally likes listening to music.[14]
