This Force-sensitive Lepi female, named Lop, lived on the planet Tao throughout the Imperial Era. Originally not from Tao, she was an orphaned and enslaved worker for the occupying Galactic Empire. Lop made her escape and was taken in by Boss Yasaburō of the influential Yasaburō clan, a decision driven by his daughter, Ochō.
Years later, a rebellion against the Empire divided Yasaburō and Ochō. Lop was caught in the middle, attempting to bring peace between her father, who backed the rebellion, and her sister, who opposed it. Eventually, Ochō sided with the Empire, leading Yasaburō to train Lop in the use of their family's lightsaber so she could confront Ochō.

She was a female Lepi, specifically belonging to a subspecies, who was born on a planet other than Tao. Early on, she was brought to Tao to be a slave for the Galactic Empire. Lop became an orphan after losing her parents. At some point, she befriended a droid, named TD-4, who became her companion.

During the Imperial Era, Lop and TD-4 were on the run, trying to escape enslavement. At a market, she encountered a human father, Yasaburō, and his young daughter, Ochō. Yasaburō had lost sight in one of his eyes due to a scar. Noticing the young Lepi attempting to steal some fruit, the humans inquired about Lop's background and family. Hearing Lop's stomach rumble with hunger, Ochō insisted that Lop join their family, convinced of Lop's good nature. Ochō eagerly took Lop to play on the beach, effectively persuading her father to adopt her. Yasaburō committed to cleaning Lop up and feeding her well. TD-4 then deactivated Lop's shock collar and created a hologram of them smiling together on the beach.
Lop and Ochō grew to see each other as sisters, and Yasaburō embraced Lop as his own daughter, with Lop referring to him as her father.

Seven years after Lop became a part of the Yasaburō clan, the Imperial base on Tao was attacked. An explosion shook the local town, and Lop awoke amidst the resulting smoke and debris. Upon regaining consciousness, she put on her side glasses to view the wreckage using infrared vision, before overhearing Ochō confronting Yasaburō about the incident. Ochō questioned their father about his involvement, lamenting the town's destruction. Hearing this, Lop voiced her disbelief that her father was responsible for the explosion. She hurried to the scene where Yasaburō and Ochō were arguing, surrounded by members of their clan.
Ochō expressed her outrage at her father's attack on the Imperial base, while Yasaburō defended his support for the insurgency against the Empire, citing the Empire's pollution and exploitation of their planet. Clan members attempted to separate the arguing father and daughter, urging them to flee before Imperial troops arrived. Seeing Lop approach, one clan member pleaded with her to intervene. Lop begged her family to stop fighting, insisting that there was no reason for them to be at odds. Yasaburō silenced Lop, stating that it was a matter for the family head to resolve. Ochō asserted her right to express her opinion as the next head of the family, denouncing her father's anti-Imperial stance as "stubborn opposition to development" and misguided. The argument continued as Lop watched on. As stormtroopers approached on speeder bikes, the crowd dispersed.
While driving in a landspeeder with Ochō, Lop suggested that her sister consider their Father's perspective on the Empire and their homeworld. Ochō doubted that Yasaburō would understand her point of view, but Lop expressed her desire for their family to stop fighting, emphasizing their familial bond. Despite not being native to Tao, Lop had grown to feel at home there and could empathize with Yasaburō's resentment towards the Empire's environmental damage. Ochō claimed to share those feelings, expressing her love for Tao and her father, and arguing that supporting the Empire was necessary "for the sake of our future."
Lop and Ochō were stopped at an Imperial checkpoint on a bridge by an Imperial officer. The officer stated that he had been expecting Ochō, prompting Lop to question whether her sister knew him. The officer confirmed their acquaintance, describing Ochō as "sensible enough" to recognize the advantages offered by the Empire. He claimed that Ochō had promised to quell the insurrection before it escalated but had failed to do so. Distraught, Lop asked Ochō if she had indeed attempted to stop Yasaburō without even speaking to him first. Ochō confirmed this, stating that she could no longer "leave it up to" their father. The officer then warned that the Empire would make life even harder for the Yasaburō clan. He invited Ochō to join the Empire's "redevelopment initiative," suggesting that together they could end the bloodshed. Ochō accepted, cutting her hair and leaving the long braid in Lop's hands.

After Ochō aligned herself with the Imperial forces, Lop, accompanied by TD-4, fled from the bridge, overwhelmed with sorrow, eventually finding herself in the marketplace where she had first met Ochō seven years prior. She then made her way back to her mountain residence at the Yasaburō household, only to discover that almost all of the clan's employees had departed. Upon her return, she inquired about the whereabouts of her clan, to which Yasaburō responded that nearly all the employees had left, but not before requesting paid time off. Lop's father then asked about Ochō's location. In response, Lop somberly handed Yasaburō Ochō's braid of hair and informed him that Ochō had joined the Empire. The family boss was saddened and angered by this revelation. Lop explained that the Empire had tasked Ochō with persuading him to abandon what they termed his "terrorist plans," and that if she failed, they would retaliate against the Yasaburō clan.
Lop then confided in her father, expressing her desire to drive the Empire away from Tao and rebuild their family. In response, her father led Lop to a candle-lit chamber deep within their home. Yasaburō apologized for seemingly favoring Ochō over Lop. Yasaburō then began teaching Lop about their family's history and performing a ritual of inheritance, designating Lop as his heir.
Centuries ago, a Jedi had arrived on Tao, settling on the planet and eventually passing away there. Before his death, the Jedi encountered an ancestor of the Yasaburō clan to whom he entrusted his lightsaber and provided training in lightsaber combat. Subsequently, the lightsaber became a Yasaburō family heirloom, passed down through generations of the Yasaburō family. Each family leader taught their successor lightsaber combat and passed on the blade as inheritance, symbolizing the bond between parent and child. Yasaburō entrusted the saber to Lop, declaring her his successor as clan leader. Lop was humbled but respectfully accepted the honor. Yasaburō told his daughter that this might be the end of their family, but he was glad she was a part of it. He told Lop to wait at home while he tried to retrieve Ochō and repatriate her to the family. Before he left, Lop told her dad that Ochō still loved him, which consoled him.
After waiting for some time, Lop heard an explosion at the Imperial base. Lop mounted a speeder and rushed to the base. Eventually, Lop jumped off a bridge to avoid stormtroopers. After the speeder was destroyed, she and TD glided to the base's interior via umbrella. Once inside, her presence distracted her dad, who got blinded by Ochō. Lop ran to Yasaburō's side, where he asked Lop to save her sister, and admitted his failure as Ochō's father. Ochō then angrily leapt to finish her father off, but was blocked by Lop wielding the heirloom lightsaber, surprising Ochō. Yasaburō explained to her that he passed it to his other daughter because of his belief that, when it comes to inheritance, there are more important things than blood. Angered even further, Ochō attacked Lop, who pleaded with her sister to return home. TD-14 projected the original hologram of their family taken just after Lop was adopted, but was cut down by Ochō. Saddened, but made more determined by the destruction of her droid, Lop awakened her force and vowed to bring her sister's real self back while clashing with her. Lop used the Force to summon one of her father's sai and destroyed Ochō's electric staff, before slashing at her sister, scarring Ocho's chest and knocking her off of the edge of the base. Ochō survived the blow and landed on an Imperial ship about to leave Tao. The sisters gave each other one last stare before the ship fled. Afterwards, Lop picked up TD-4's head which again projected the family hologram. As she watched the recording, she repeated the younger Ochō's hopes that one day they would be a proper family.

Lop possessed a strong sense of empathy. When Ochō and Yasaburō found themselves on opposing sides of the rebellion on Tao, members of the Yasaburō clan turned to her to mediate between her adopted sister and father. Lop urged Ochō to consider Yasaburō's feelings regarding the Empire and their homeworld, hoping to resolve the tensions within their family. Despite being born on another planet, Lop came to feel at home on Tao.
Even as a runaway slave, Lop demonstrated remarkable agility and nimbleness, capable of scaling buildings by leaping between walls and jumping from great heights without injury. Her skills enabled her to escape Imperial slavery and evade capture by Imperial forces.
As a Force-sensitive individual, Lop had the ability to use telekinesis. She demonstrated this when she summoned her father's dagger to her side during her fight with Ochō. She also developed proficiency with a lightsaber, as evidenced by her use of the Yasaburō family heirloom lightsaber in her duel against Ochō.
Lop received the Yasaburō clan lightsaber from her father Yasaburō as her inheritance, in accordance with the Yasaburō clan's tradition of passing down the saber and lightsaber swordsmanship through the generations. She also wore a pair of side glasses that could display information or reveal her surroundings in the infrared spectrum, and she carried an umbrella that allowed her to glide short distances.
Lop was featured in "Lop & Ochō," a short film within the Star Wars: Visions series, written by Sayawaka and directed by Yuki Igarashi. The short, produced by Geno Studio, was released on Disney+ on September 22, 2021. Igarashi aimed to create a symbolic character who was also a non-human being. According to behind-the-scenes featurettes, the creators intended Lop to be based on a pre-existing rabbit alien species. They learned about Jaxxon and his species, the Lepi, from Coachelle Prime, which inspired them to make Lop a member of a shorter subspecies.
