Description
Beni Walker is a girl who holds the core of the Tenkai Knight known as Venetta, making her the first female Tenkai Knight. In her human form on Earth, she appears to be around thirteen years old, with long pink hair and turquoise eyes. Her outfit consists of a yellowish green neckerchief, a black t-shirt with red suspenders, a dark red headband, hot pink shorts with a white belt, and purple boots. As Venetta, her armor is pink with purple highlights and green accents, designed with a spider motif that includes a crown-like attachment on her forehead and a spider-shaped shield on her back.

Beni has a curious and inquisitive nature, often displaying a strong belief in her own intelligence, particularly in comparison to boys whom she frequently comments on as being "typical" and prone to messing things up. She is confident in her ability to use charm to extract information from others, especially Guren. This arrogance is noted by others, with Gen observing that she has a habit of underestimating her opponents. Despite this, she demonstrates a nuanced understanding of the conflict surrounding Quarton and its implications for both worlds.

Her motivations are rooted in a personal tragedy, as it was revealed that her childhood was ruined because of events connected to Quarton, leading her to desire the destruction of both the human world and Quarton. This goal drives her to operate with her own agenda, using both allies and enemies as means to an end without forming genuine attachments. She is distrustful of authority figures like Vilius and prefers to work alone or in temporary partnerships that serve her purposes.

Within the story, Beni begins as a rogue operative working alongside Gen in the search for the Black Dragon Key. She later manages to convince Guren, Ceylan, Toxsa, and Chooki to help her in this search, taking command of their operation. Her loyalties are consistently ambiguous; she has worked with Gen, Guardian Eurus, and eventually Vilius, but each alliance is revealed to be a tactical move to advance her own objectives. She eventually joins the Corrupted side to help Vilius find the Tenkai Fortress, but later betrays him and ultimately aligns with the Tenkai Knights. She maintains control of a warehouse that serves as her personal portal to Quarton.

Key relationships in her life include her former partnership with Gen, which dissolves when he decides to work on the right side by joining the Knights, leading her to accuse him of failing in his mission. She shows a particular interest in Guren, partly because he does not fit her preconceived notions about boys, and there are hints that she may have developed feelings for him. Guardian Eurus also served as one of her mentors during her search for the Black Dragon Key. Her interactions with the other Knights are often manipulative, as she uses flattery and deception to get what she wants from them.

Beni undergoes a significant character development from a major antagonist working against the Tenkai Knights to a protagonist who fights alongside them. She initially operates as a rogue agent with her own agenda, then officially joins the Corrupted, but later betrays them and becomes an ally to the Knights. This shift represents a move away from her solitary, manipulative approach toward accepting cooperation with others, though her independent streak remains a defining trait.

As Venetta, she possesses several notable abilities. She is exceptionally quick and agile in combat, wielding twin daggers with proficiency. Her spider-themed powers include the ability to shoot purple webs to entangle enemies and the use of a shield that functions as a Dark Energy Blaster, capable of firing powerful blasts. She can combine her twin daggers to form a staff and has demonstrated the ability to teleport, disappearing in a cloud of smoke. Venetta is also capable of Robofusion, merging with another entity to form a new, more powerful combined form, as seen when she took on a snake-like Robofusion. She has shown the ability to hold her own against multiple opponents simultaneously and can fight effectively against Knights in their X Modes while remaining in her basic form.
