Beni

Beni (Japanese: ベニ, Beni, Korean: 베니) is a major antagonist, but later becomes one of protagonist s in  Tenkai Knights. She is in the possession of the core of the evil Tenkai Knight, Venetta, and is also the first female Tenkai Knight.

She is voiced by Nika Futterman in English and by Masumi Asano in Japanese.

Appearance
Beni is a thirteen-year-old girl with long pink hair past her waist that splits into twin tails and sleepy, turquoise eyes. She wears a small light, lime green neckerchief, a black top, and a dark red headband. Her lower outfit consists of a pair of white-belted magenta shorts with red suspenders, and orchid uggs.

Personality
Beni can be curious, but acknowledges of Quarton more than most characters. She seems to think she can "charm" her way to any boy's life to find any information. She also seems to be close to Gen. She seems to think she's more clever than boys, or at least believes herself to be more intelligent than them, since she is constantly commenting about how "typical" boys are. Due to her thoughts of how boys throughout the series seem to always get tricked by her acts. (This includes scenes of Guren trusting her, Ceylan often seeing her as an annoyance, Chooki judging her to be a "Dudechick," Toxsa easily falling for her flattery, and her comment to Gen of how "boys mess up everything.") Whether or not this comes from personal pride remains to be seen. Beni may also be distrustful of Vilius since, in "Double Crossed", she informs Gen about Vilius assembling an army and wondering if he is remotely interested in the Corrupted leader's plan. Beni appears to have her own agenda after the boys defeated Vilius for the second time. She helped Slyger in "Elemental Knights", and she seemed to understand immediately that Vilius had captured the Guardians. In "Beware Betrayal", Beni's personality changes constantly, because of her positive reactions to the perks of not choosing Good or Evil, until later, she gave her negative thoughts of "Friendship" and how it would ruin people.

Beni now likes friends and is a lot nicer by the final episode so has joined the knights

In the Series
Beni first appeared in "Lost Key", where she met up with Gen, making him realize that he shouldn't be a one-man team anymore.

She then appeared in "Tenkai Rogue", when she attacked two Corekai soldiers on Quarton. Later on, she disguised herself as a clueless young girl to find out why Gen was so interested in Guren. Back on Quarton, she, as Venetta, attacked Bravenwolf, Tributon, Lydendor, and Valorn.

Eversince "The Key to Evil", she has been trying to help in the search for the Black Dragon Key.

In "Dromus Betrayed", she managed to convince Guren, Ceylan, Toxsa, and Chooki to help her find the Black Dragon Key, and took command of the operation to do so. Despite having pledged herself as trustworthy to Guren, her intentions and the absence of Guardian Eurus from the Guardians' battle with Vilius left room for further suspicion.

In "A New Knight", she complains at Gen for failing to awaken the Tenkai Dragon and how boys will get in the way. Gen then decides to not be partners anymore and starting from here, she went rogue.

Her status changed from rogue to evil in "Beware Betrayal", where she decided to help Vilius find the Tenkai Fortress by finding the Tenkai Stone, which was located in her room. Later, Beni saw Guren twice. The first time was telling Guren which side she's on and the second time was telling him and Ceylan why its best to work alone. On Quarton, she was about to defeat Bravenwolf, which caused Ceylan, as Tributon, to unlock Elemental Titan Mode and save Bravenwolf. Beni then escapes and tells Vilius the location of the Tenkai Fortress. Vilius then trusts her and gives her the right to do anything she wants, as long as the Fortress is found.

At one point, she was working for Vilius, as shown when Granox and Slyger recognize Venetta on Earth. At another point, she was working for Gen."

Guren Nash
Guren and Beni met when she approached him and staged herself tripping nearby. He caught her before she fell, and from there, she tricked him by pretending to become friends with him, only to betray him and the other Tenkai Knights shortly after, revealing her true intentions. After Vilius' initial defeat, she is still reluctant to befriending Guren, who is willing to accept her friendship should she choose to join the good side. However, she still seems to care only about herself, and occasionally still aids Vilius. However, she seems to be warming up to Guren and swaying towards accepting his friendship, as shown in Episode 52. Though, she still remains stubborn and hesitant.

Ceylan Jones
Ceylan met Beni the same time the other Tenkai Knights did (aside from Guren). He was lured into her trap and has always been very cautious and mistrusting around her. He also has a nickname for her, often calling her 'Pinky' whenever she shows up.

Toxsa Dalton
Just like the other Tenkai Knights, Toxsa met Beni the day they were trapped. He also seems irritated with her presence, and will often express his annoyance when she is around.

Chooki Mason
Chooki also met her the day the other Tenkai Knights were deceived. He is also not pleased whenever she happens to be around, but he's the most indifferent to her, as well.

Gen
Beni and Gen used to work with each other to find the Black Key. In "A New Knight", he left her and decided to work on the right side by joining the Knights. Gen has stated that if Beni wanted to join the Tenkai Knights, she could. However, she simply replied by despising the thought of having friends, saying that friends only let you down.

Eurus
Beni was once working with Eurus for the search of the Black Key and he was one of her mentors
