Dragon²

Dragon² is the thirty-ninth episode of Tenkai Knights. It first aired on May 29, 2014 on GO! in Australia.

Plot
The episode starts with Granox telling Villius that he and Slyger will lead an attack on the Tenkai Fortress. Villius harshly berates him, calling himse l f  a fool in the process to even think he'd let them lead an attack on the Fortress. Slyger begins to repeat what Villius said last time, however Villius cuts him off, saying that he'd said whoever controls the Fortress controls the two worlds, and for that reason it needs to be recaptured, but he will lead the attack himself. When Slyger asks about what he and Granox should do, Villius tells them to try being helpful for once. He also adds that if they're lucky, he'll let them pick up the pieces of the Tenkai Knights after he's "blasted them to atoms".

Following the opening sequence, the episode cuts to Mr. White's shop,with Guren and the Knights recapping how they found the Fortress, but can't get anywhere near it. Mr. White suggests they could penetrate the force field if they increased their Tenkai Energy somehow. However, he himself doesn't know how.

We then cut to the park, where Guren explains how the fortress is connected to the brickification problem, and if they don't penetrate the force field soon, it'll come back again. Toxsa is skeptical and cracks a joke about how Mr. White's teapot was brickified. However, Chooki tells him that EVERYONE on Earth would be brick-like, scaring him. Ceylan makes it worse by joking about everyone looking like 8-bit graphics. This horrifies Toxsa greatly, however, Guren tells them to focus on finding a way to increase their Tenkai Energy.

Afterwards, we cut to different scenes of the Knights' methods for increasing their Energy: Guren "trains" with Max, Chooki goes fishing, Ceylan falls asleep at his laptop, and Toxsa, who is incredibly paranoid due to Chooki and Ceylan's brickification jokes, freaks out upon seeing anything square shaped. Then we cut to Gen's dojo, where he and Guren spar, with Guren beating Gen quickly. Gen thinks Max must have been a good training partner, because Guren has definitely gotten better. Guren tells Gen about how he and the Knights are trying to increase their Tenkai Energy to access the Tenkai Fortress, and asks for Gen's help, however Gen declines. Gen theorizes if someone had a key to open the Tenkai Fortress, and Guren asks who.

The scene switches to Beni's apartment, where she serves Gen some tea, telling him it's been a while. Gen cuts to the chase and asks Beni what she knows about the Fortress. Beni asks what she gets in return, and Gen tells her to stop joking, and he knows that she knows. Beni says that if he joins her like he did back when they served Villius, she'd tell him her secret. Gen warns her that if she causes trouble for the Knights, they'll never be partners again, and they'd be enemies. Beni asks him when he joined the Knights, but he said he hasn't, and tells her to "just back off". Beni mocks him for this, calling him soft, and Gen gives up on trying to get information out her. As he leaves, Beni warns him, telling him not to be surprised when his new friends let him down, because they will let him down, sooner or later. After Gen leaves, Beni takes out her Fortress key and dismisses the thought of having friends when she has the key.

Meanwhile, the boys are busy walking through the main part of town, and Toxsa flips out after seeing square-shaped melons, screaming that the brickification started. Ceylan and the others drag him to a sidewalk and calm him down, telling him the melons are grown that way naturally, and Ceylan reveals he and Chooki were only joking. Toxsa manages to calm down, and the boys are suddenly called by a little girl for help, saying something bad happened. She reveals her puppy went to get his ball out of a hole and got stuck. Toxsa ends up rescuing the dog, and after getting the pup out, sees a ball and assumes he got stuck because he lost his ball. Toxsa then freaks out, revealing the ball had underwent Brickification.

The scene switches to Quarton, where Villius has assembled a massive army to seize the Fortress. The Corrupted Guardians are also present, with Boreas asking why they're there in the first place. Eurus says Villus wants to remind them of their helplessness. Zephyrus says they have to admire Villius's power. Notus says he can respect, it but to admire it disgusts him. The Knights arrive on Quarton, where Villius says his victory wouldn't be complete without them. The Knights activate their Elemental Titan Modes, and begin taking out some troops. However, Vilius reveals his own Dark Tempest Vilius Titan Mode, and mocks the Knights for underestimating him, but they aren't phased. Beni watches from behind a mountain as Bravenwolf takes on Villius. Tributon and Valorn try to help, but are intercepted by Granox. Dromus drops in and begins fighting Villius. Bravenwolf tries to help, but is attacked by Slyger and his Fire Raptor. Tributon engages Slyger, and tells Bravenwolf to get back to fighting Villius.

Dromus is nearly offed by Villius, much to the watching Venetta's concern, only to be saved by Bravenwolf. Bravenwolf then uses his Tenkai Firesword on Villius after Gen distracts the Corrupted leader. However, Villius suddenly ejects his Dragon Cube, and extracts the other four from the Guardians. Villius then assembles the Dark Tenkai Dragon, who begins to wipe out the Corekai soldiers. However, the Knights and Dromus use their own Dragon Cubes to create the Good Tenkai Dragon. As both dragons clash, Villius yells for his dragon to end the Knights. As the two dragons fireat each other, their attacks collide with each other in a stalemate. We then see something in the Fortress glowing. Outside, the two dragons' power cause a massive explosion that covers all of Quarton. In the aftermath, Guren wakes up, and sees that Quarton has become jungle-like. He calls out for Ceylan, Gen and the others, but no one answers, and the episode ends on a cliffhanger.
