Terezi can be civil, flirty and derisive in her interactions. Her drive for justice results in some cruel actions, the majority of which she has been shown to be deeply affected by and regret later on. She is almost always grinning and in many panels, it appears as though she is cackling madly. From her conversations with the kids, Terezi's attitude differs depending on who she is talking to: she acts helpful towards Rose, dubs them 'hatefriends' and tells her about Sburb. This approach may be a part of her trolling of John by pretending to be helpful towards him (through insulting him and using a kind of angry politeness) and giving him advice that leads to his death in the alternate timeline. After John avoids his death, Terezi seems to have since shown remorse for her actions and claimed she felt awful for 'killing' him; even helping him through the second gate into the Land of Light and Rain to earn his trust. Her trolling of Dave has been bizarre but effective, causing him to completely lose his cool. She often takes images of Earth pop-culture characters she thinks are similar to Dave and (crudely) draws over the picture, claiming to make it look even more like him. It is worthy to note she may have had an interest in Karkat. During one conversation HS with Terezi, John jokingly said that Karkat was “basically in love with you”, and she reacted with surprise, asking him if Karkat told him that in confidence and even asking him to copy/paste the exact words, a road which John refused to go down. It has since been shown that they were most likely Matesprits.

Like the other trolls, Terezi is able to access the kids' adventures using Trollian, but Terezi stays linear rather than skipping around because time shenanigans give her a headache, which may mean she was more efficient in her trolling than the others. Her overall tone of speech is reminiscent of Jade's speaking patterns.

She has a keen interest in law and justice, has studied Alternian law thoroughly, and holds a particular fascination for orchestrating the demise of the wicked HS , although that might not be why she caused John's death. The incident might have simply been a vain effort from her point of view, because in a conversation HS with Davesprite, she states that she knew John wouldn't die, as she could see him alive in the future from her timeline application in Trollian, and given that she felt guilty about the way John trusted her trolling, this is most likely the case. She also has more lighthearted interests like dragons or collecting plushies and scales to put on her walls. She has a habit of using chalks to draw on walls for use in her live-action roleplays, and later also uses them to communicate HS with the exiled Black Queen. Her favorite color appears to be red, saying that it is so decadent HS and the most delicious color HS , probably contributing to her attraction to Karkat and to Dave, the two Knights.

Terezi is very interested in other people's blood color, but that may be more out of curiosity than hierarchy. Terezi's own blood is in the teal end of blue, keeping her out of the aristocracy's conspiracy games until she's over her head in Sgrub beings.

Terezi eventually admits that she has never felt truly complete, not even in her moiraillegiance with Vriska, and accepts that she probably never will. HS

Terezi's obsession with justice stems from her association with the constellation Libra, represented by the scales of justice; her fondness for dragons and their “COLORFUL SCALES” HS is also a pun on the constellation's symbol. Terezi's perfectly conical or triangular horns also bear a passing resemblance to the strings on either side of a classical depiction of a set of scales. Her dual association with law and mythical serpents may also allude to the concept of Draconian law, a term which could be seen as aptly describing the state of law on Alternia.

In ancient times, Libra was once merely seen as the claws of Scorpio, possibly referenced in Terezi's complicated relationship with Vriska Serket.

Terezi's blindness is a reference to the blind mythical figure of Lady Justice, often associated with the Libra constellation. Like many of the other trolls, Terezi is also heavily inspired by various popular comic book characters; the various cane weapons and scarlet sunglasses she uses as a blind, super-sensory lawyer are all similar to the iconic memorabilia associated with Marvel superhero Daredevil; though she has of course never heard of this Earth character. HS Her use of a “DOUBLE-HEADED” HS Troll Caegar - with one side of the face disfigured - to measure out justice also evokes the gimmick of Batman adversary Two-Face: but of course Terezi doesn't know who that is either. HS Terezi's particular coin seems to depict the ancient Roman goddess Venus; the constellation of Libra is "ruled by" the planet Venus.

Terezi borrows her title of Seer from Kankri Vantas; Kankri's dancestor Karkat Vantas likewise borrows his Knight title from Terezi's dancestor Latula Pyrope. In addition to her family connection to the class, Terezi's torrid relationships with the Knights Karkat and Dave Strider may owe to the close relationship between knights and dragons in folklore.

Etymology

The name Terezi was first proposed by MSPA Forums user cashewSquared, and is the word for 'balance' and the name of the Libra constellation in various languages, derived from Persian tarâzu, meaning scales. Tiresias was also a blind Seer in Ancient Greek myth. Suggested by Dragoshi, a 'pyrope' is a variety of red garnet - from Greek pyro, 'fire' and ope, 'eyes', referencing her and her ancestor's red glare - in the pyralspite group.

The gallows in Terezi's trolltag refers to the apparatus on which "justice" is dispensed through hanging, which was the ultimate fate of her ancestor Redglare. “Calibrator” contains the word Libra within it; to calibrate is also to set something up through careful measurement, like someone would do using a set of scales.

Terezi's blindness is indeed real and was caused by Vriska in retaliation for the aforementioned incident. Vriska did this via a Psychic Double Reacharound HS through Tavros and Terezi's Lusus . She used Tavros's ability to commune with animals to control Terezi's Lusus who would then speak to Terezi (as she was unable to control Terezi directly), forcing her to sleepwalk away from her tree and stare into the blinding Alternian sun, effectively burning her eyes and blinding her. At the same time, dream Terezi walked out on Prospit and stared into the heart of Skaia. Terezi's dream self awoke on Prospit, and her Lusus, still in its egg, used telepathy to teach her the skills to function without vision, by smelling and tasting her surroundings. This all happens in [S] Make her pay. HS In a conversation HS with Karkat, she says that her dream self's blindness is because deep down, she wants to be blind.

She stopped Flarping after Tavros' injury, the only type of role-playing she continues being chat-based furry roleplay with Nepeta Leijon, in which she plays a dragon who thinks nothing but of devouring everything in its sight. She seems to enjoy these sessions. HS

Though she is blind, Terezi can "smell" and "taste" colors. She makes references to being able to "smell" the text of others while chatting online, clearly confusing the Homestuck Kids. When using her computer, she has a fondness for licking her monitor (and chalk), and like all of the other trolls, a graphic symbol of her corresponding zodiac sign appears at the back. She was taught how to sense the world through scent and such by her future custodian.

She was to be the original leader of the Red Team; however, she surrendered the position to Karkat, probably out of understanding that the position was essentially meaningless.

Her Land has been revealed to be the Land of Thought and Flow. Her exile is Snowman. Snowman switched from Vriska to Terezi due to difficulties controlling Vriska as she was stubborn and refused to listen or acknowledge the orders. Instead, Snowman chose someone less stubborn and more creative. Terezi would then be tasked with the mission of exiling the Archagent Jack Noir, during a brief "conversation" between Terezi and Snowman, thanks to some chalk she keeps in her Sylladex. In time she and Vriska would carry out this mission.

Post-Hivebent

Terezi contacts Rose Lalonde after she enters The Medium and, rather than trolling her (though she claims to be 'hatefriends' with Rose), offers constructive information about the titles of each Sburb player and the voice of the exile that Rose hears. She mentions the fact that Earth is doomed no matter what, and that the exiles are responsible for restoring life. Terezi also knows about Agents but refuses to tell Rose about them, saying that it would be more constructive to talk in the future.

It was Terezi who first discovered the humans. She received a money transfer from Dave, which her future self had set up. Her interest was taken due to the large sum of money and the use of the numbers of the blind prophets, with Sollux's help she was able to backtrack the transfer. She takes an interest in the cool kid she discovers and decides to support him once he enters the Medium.

After the Doomed Dave is killed by Bec Noir at his quest bed HS , she runs from the room in tears, seemingly very upset. During her broodings, the dead body of Tavros falls from the ceiling; he had been run through the chest with his own lance. A forensic analysis of the corpse with the help of three of her Scalemates leads to two of them being cast into the void, likely attracting the attention of a murderous Gamzee in the process. She concludes that the culprit was Vriska within seconds, but pretends that the results were inconclusive because otherwise she would have no fun with the process. In an attempt to revive him, she removes her glasses and smooches his corpse HS . Her glasses are soon after found by Gamzee, who uses them to contact Karkat, leaving the sole message of “honk”.

She is later found investigating the computer room, where she laments the loss of her forensics team and states how hard it is to investigate a murder with no body (referring to the bloody mess made by Kanaya's body). She then walks over to the horn pile, where she encounters Feferi's corpse. She declares it a “textbook impaling”, showing that she is still oblivious to the fact that Eridan also went on a murderous rampage. She also notices two puncture wounds on the corpse's neck, which match up with Kanaya's fangs, but she formulates a completely and totally absurd theory that it was Vriska, who had developed a taste for blood. She acknowledges that this really doesn't make much sense.

Horns and Face: Like all trolls, she has grey skin, pointed ears, and sharp, angular features. Sticking out of her short, messy black hair are two small, simple yellow-orange horns with a slight taper. Eyes and Eyewear: Terezi is blind (as a result of being blinded by Vriska with a mind-controlled flour sifter), so she is almost always seen wearing bright red, opaque, cat-eye-shaped shades/glasses. Underneath, her eyes are completely red and sightless. Clothing: She wears a grey shirt (typically black) featuring her astrological sign, Libra (Ω), printed in a teal-blue color. She pairs this with dark pants or a skirt depending on the outfit iteration, and distinct red shoes.
