Guren Nash

Guren  (Japanese: 大神グレン, Ōgami Guren, Guren Ōgami) is the main character of Tenkai Knights. He is in possession of the core of the Tenkai Knight, Bravenwolf. However, ever since he unlocked Elemental Mode, he goes by the name Bravenwolf Tenkai Firestorm.

Out of the four boys, Guren is the closest to Ceylan Jones.

He is voiced by Johnny Yong Bosch in English and by Meguru Takahashi in Japanese.

Appearance
Guren is 12 years old, has black and red hair, and blue-violet eyes. He wears a red t-shirt, and underneath is a white long sleeve shirt with his watch. He also wears blue cargo jeans with beige suspenders hanging on the sides and red shoes. His primary element is fire and he has a specialty of power when Bravenwolf.

Personality
He has a knack for leadership (though he still has to grow into the role) and tries not to show fear when facing difficult challenges. Guren is described as always having a positive attitude, and is always there for his friends. He can sometimes be vain, especially when dealing with his father, who never seems to have time for him. He is very loyal to his friends, and often gets uncontrollably angry when someone puts them in harms way or threatens them. In the end, Guren always does what is right, which makes him the perfect leader for the Tenkai Knights (despite repeatedly stating that the Knights have no leader, but he does a good job at it).

In the Series
In "Two Worlds", Guren moves to Benham City, where his father found work, to Guren's bitter disappointment, pointing out that he doesn't want to change his location every few years. In his new school, he becomes friends with Ceylan, with whom he goes to the Shop of Wonders, where he spots a white brick like toy. After he manages to change the brick into the form of a robot, the shops owner, Mr. White, let's him take it for free. That night, Guren has a dream of himself as the robot he'd just obtained, fighting against an evil robot. The next day he tells Ceylan about his dream, only to discover Ceylan had the exact same dream. The pair decide to ask Mr. White about the bricks, but when they arrive at his shop they can't find him. Guren, curiously heads down to the basement. When he and Ceylan enter, they are apparently attacked by a mysterious robot. Then Guren is suddenly transported to Quarton. When Guren awakens, he discovers that he's become the robot hero Bravenwolf. When he learns that Ceylan, now Tributon is being held captive, he goes to rescue him. After they fought the armies of Vilius for the first time, Guren and Ceylan are returned to Earth.

In "Tenkai Dragon Cube", Guren and Ceylan attempt to help the Corekai in their struggle against Vilius. During a battle, Guren is overwhelmed by Slyger and Granox, until he and Tributon are saved by the timely arrival of Knights Lydendor and Valorn.

In "The Rising Fire", Guren and Ceylan try to track down the other Knights back on earth. They eventually meet two boys, Chooki and Toxsa. Guren approaches the two with the offer that they should form one team to save Quarton. Both boys initially refuse, but in the end, they all agree on working together to find the Dragon Cubes and save Quarton.

In "The Tenkai Kid", Guren and the other boys ask Mr. White for some answers about Quarton, but instead he makes them clean his store. Believing Mr. White is giving them physical training, Guren embraces the workload. Later, on Quarton, Vilius appears and Guren attempts to fight him with what he'd learned. When it appears Vilius is going to defeat him, Guren unlocks his Titan Mode Transformation for the first time and forces Vilius to retreat.

In "Tributon Extreme", Guren meets a mysterious new student by the name of Gen. While on Quarton, Guren witnesses Tributon achieves Titan mode and faces off against Dromus, a new Tenkai Knight who appears to be a doppleganger of Bravenwolf who takes the fourth Dragon Cube with him.

When Commander Beag sacrifices himself in "Valley of Secrets" to save the Tenkai Knights, Guren and the other boys develop a new Robofusion. This time, they transform into the Air Lancer Jet. Feeling terrible about what happened, Guren and the others set out to find and rescue Beag. When they arrive in the valley, they discover that Beag and his men are in fact alive and rescue them.

In "Two Sides to Every Coin", Guren receives advice from Gen about "choosing the side he wants" after having come up with a plan with the Corekai to infiltrate the Dark Fortress to find the last Dragon Cube. So when Dromus attacks with his Core Corrupter, Guren remembers Gen's advice, and is able to turn the corrupted back to their old selves, thus capturing the Dragon Cube. Back on Earth, Guren's computer receives a message telling him that the "key" to revive the Tenkai Dragon is on earth, and that he is the key.

In "Dragon's Key", Guren and Chooki try to find a clue about the White Dragon Keys' location. They find a sign which takes them to another sign and another. Guren and Chooki finally find the Key and pass through booby traps guarding it. Guren gets through and takes the key.

Next, in "Vilius Unleashed", Guren and Chooki arrive with Boreas and the five Cubes are combined into one giant cube that can be only opened with the Dragon Key, awakening the Tenkai Dragon. However, despite his efforts, Dromus manages to captures the Dragon and transports it to the Corrupted headquarters. During his battle with Vilius, Guren reveals his human identity before destroying him.

In "Tenkai Rogue", Beni disguised herself to track down Guren. He, not knowing her true intentions, finds her to be an interesting person as they hang out together.

Then, in "Oh No, I Didn't", Guren's leadership skills are put to the test after being confronted by Ceylan about what he brings to the team. He ends up helping Ceylan get rid of his self-doubt and regain his confidence.

After, in "Robofusion!", Guren is worried about Chooki when he cannot catch a fish, which everybody else (including Guren) excels at. However, Guren doesn't know how to help him, but in the end Chooki figures it out for himself.

In "The Key to Evil", Beni tricks the boys into being transported to Quarton where they are challenged by duplicates of themselves created by Eurus and unlocked Titan Fusion.

During a plot twist in "Extreme Titan", Toxsa's sister Wakamei finds out that the boys are the Tenkai Knights and Guren gives her some good advice about letting Toxsa grow up on his own.

In "Double Crossed", Guren questions if his relationship with Gen, or Gen's moodiness and reclusion is his fault for not understanding Gen.

Next in "Checkmate", Guren is disappointed that he doesn't get to spend a lot of time with his father, who is still working on Benham Tower. He is also confirmed to be the Corekai's most powerful and valuable person.

In "Dromus Betrayed", Guren saves Beni from being annihilated by Dromus. He tries to give her a chance, but finds it hard to trust her after their experiences with her. However, he only does this, in order to gain the results of her helping the Tenkai Knights find the Black Dragon Key on Earth.
