Gen Inukai

Gen (Japanese: 犬飼ゲン, Inukai Gen, Gen Inukai, Korean: 켄) was a major antagonist, but later became one of the main protagonists in Tenkai Knights. He is in the possession of the core of Dromus, a formerly evil character who now works with the Tenkai Knights and bears a strong resemblance to Bravenwolf. However, ever since he unlocked Elemental Mode, he goes by the name, Dromus Tenkai Whirlwind.

He is voiced by Yuri Lowenthal in English and by Miyuki Sawashiro in Japanese.

Appearance
Gen is a tall, 13-year-old boy. His eyes have a sharp red color, with the right eye being covered by his emo flip from his dark auburn hair that's spiky, pushed-back. He wears a tall-collared, zipped up, black jacket made of what appears to be leather. The jacket usually covers his mouth and has two buttons on each side that connect to each other. Gen's lower attire, consists long pants are made of the same material that his coat is made of. Which is held up by a belt with a golden-yellow buckle. Also, he wears dull, lavender leg warmers and black slip-on shoes.

Personality
Gen's personality is at first shown to be calm, cool, and collected, even stoic, though he dislikes people who need teammates because he thinks they're weak, giving him an antisocial personality to most. Although, he had described Beni as a "friend" at the end of "Lost Key." In "The Key to Evil", it was revealed that Gen wasn't always calm and collected. Gen used to be a very positive and outgoing child just like Guren. The event that changed his personality was when his mother left, leaving his father depressed, frantic and hopeless. His family fell apart, which made him shut himself from the world. He tried to keep his father happy by being "a good boy": only studying and training, instead of playing with his friends in his childhood. Ever since "A New Knight", it seems that he has changed his attitude towards Guren and the other Tenkai Knights, along with the fact that Gen becomes a supporter and part of their team. In "A New Element" he officially joined the Tenkai Knights as the fifth member and loosened his personality and collar.

Trivia

 * It's been revealed in "Dojo Mojo", that he goes to a dojo and is a 1st Degree Black Belt Master.
 * Part of Gen's Japanese surname, Inu (Japanese: 犬), means dog, and since a wolf is a dog, Dromus and Bravenwolf are dopplegangers to each other.
 * Gen appears to resemble Sasuke Uchiha from anime/manga series, Naruto. Both have the same hairstyle, clothing, and stoic personality. They even shared a dark past, a rivalry with the main hero, and looking disdain on a female teammate. While Sasuke has turned from good to bad, Gen has turned from bad to good. Also, both are voiced by Yuri Lowenthal.
 * As of "Feeling the Heat", Gen finally considers Guren as a friend.
 * Gen has a habit of proving himself to be one class higher than the Knights at everything they do. This includes Chooki's skills at basketball and chess.
 * Gen is a good strategist and understands Quarton.
 * It is unknown how Gen travels to Quarton. Guardian Eurus possibly gave him a secret portal or the ability to go to Quarton like Beni did to the knights in "The Key to Evil".

In the Series
In "Tributon Extreme", Gen transferred to Guren, Ceylan, Chooki and Toxsa's school. There, he met Guren and Ceylan for the first time. While on Quarton, Gen introduced himself to the Tenkai Knights as Dromus and took the fourth Dragon Cube with him.

In "Two Sides to Every Coin", Gen was curious if Guren is Bravenwolf and he gave him some advice about "choosing the side of the coin he wants". So when Gen, as Dromus, attacked with his Core Corrupter and witnessed Bravenwolf put his advice into practice, he realized that Bravenwolf must be Guren.

In "Dragon's Key", Gen led Guren and Chooki on a trail of clues about the White Dragon Keys' location. He put up one sign after another. When Guren and Chooki finally found the Key and passed through booby traps guarding it, Gen returned to Quarton.

Later, in "Vilius Unleashed", Gen, as Dromus, managed to capture the Tenkai Dragon after the Knights awakened it and transported it to Vilius's headquarters.

In "Tenkai Rogue", Gen was joined by Beni in his efforts to defeat the Tenkai Knights.

In "Dromus Betrayed", Gen was seen in Beni's flashback, explaining Dromus' intentions and how he was betrayed by someone in the past. However, his being Dromus was still not revealed to the Tenkai Knights by Beni.

In "Dragon Key Quest", Gen ambushed Guren and the others after they found the Black Dragon Key. After fighting with Guren over the key, Gen managed to take the Black Key from them and revealed Beni tricked them as well. Once that was done, Gen escaped them along with Beni thanks to Eurus back to Quarton.

In "The Dark Unlock", Gen explained some of his back story to Guren while the par fought, and Guren learned that Gen's life was a depressing one. Guren finally saw why Gen acted so evil.

In "A New Knight", Guren continued to try and sway Gen, Gen watched as Guren and the others continued to struggle against Vilius and the evil dragon. After Beni lectured him about how troublesome it was working with him, Gen seemed to have an epiphany. Gen jumped in and helped the other knights fight and defeat Vilius and restore both the Tenkai Dragon, and the Tenkai Energy of Quarton to normal. After that he mostly appeared only briefly, however in "Vilius Returns", he arrived on Quarton in order to help the other Knights by breaking the Tenkai Dragon back up into Dragon Cubes and saved them.

In "A New Element" Gen unlocked his Elemental Titan Mode and has officially joined the Tenkai Knights as the 5th member.
