A New Element

 is the fourty-eighth episode of Tenkai Knights. It first aired on August 10, 2014 on Teletoon in Canada.

Plot
Vilius has a new plan: he decides to let the Tenkai Knights find the stone for him and then he strikes. But while Vilius is talking about this plan with Slyger and Granox, Dromus shows up and challenges Vilius to a fight which Vilius accepts. Dromus quickly loses the fight and runs away.

Back on Earth, the Tenkai Knights are still having trouble finding the Tenkai Stone. Guren goes to the dojo and finds Gen training there. Gen challenges Guren to a fight and he easily wins. After the fight Gen walks away.

The scene changes to Kiiro, who accidently finds the Tenkai Stone among her toys. It turns out she had forgotten to give it to Guren.

Chooki, Ceylan, and Toxsa are looking for the Tenkai Stone on the beach, but they have no luck again. Then, Chooki has an even crazier idea: to go look for the Stone in the ocean. While this is happening, Ceylan sees Gen and they go ask him for help but Gen refuses. They then notice Gen is actually sad, so the three decide to tell that to Guren. Chooki asks if Guren noticed if there has been something weird with Gen lately and Guren says he's noticed. Guren then runs off without saying anything.

The scene changes to Gen, who is walking down a street and finds Granox.

Guren goes to Gen’s house but Beni is the one who shows up, as she lives next door. Guren asks her about where Gen is. While they talk, they see Gen outside, running away from Granox, so Guren and Beni go help him but Gen tells Guren to go away because the fight is his alone.

Because of this, Guren asks Gen what happened and Gen tells him he went to Quarton, fought against Vilius, and lost. Once Granox finds them again, Gen tells Guren to run away but Guren yells at Granox that he is Bravenwolf so he can spare Gen. So Granox says he’s going to capture both instead, but he is stopped because Beni sends him to Quarton one more time.

While Beni and Guren talk, Gen tries to walk away but Guren interrupts Beni to ask Gen why he did what he did. By the end, Guren says “Why didn’t you tell us? I thought we were friends!” Gen replies with “Maybe that’s why I did it! I didn’t want my friends to be at risk”, and then walks away.

Chooki is at his own house, complaining about not having found the Stone yet. Then Kiiro shows up to ask him to take her to Guren. Once Chooki asks her what she wants to do with Guren, Kiiro tells him she has a lucky charm to give to Guren.

The scene changes to Gen and Beni. She calls him crazy for challenging Vilius to a fight, mainly now that they all fight together. She tells him he should stop fighting alone and start fighting together with the others because friendship may be the biggest power one can ask for.

Kiiro is finally with the four Tenkai Knights and she gives Guren the lucky charm. However, once the four see what the lucky charm looks like, they are surprised to find out that the lucky charm Beni gave her was actually the Tenkai Stone they had been looking for.

They make a huge celebration about finding the Stone in front of Kiiro, but Kiiro obviously knows nothing about Quarton so Guren warns them to stop talking about it in front of her.

Mr. White offers to take Kiiro home while the Tenkai Knights go to Quarton but he also says they can’t take the key to Quarton just like that, they need to take a special spaceship with them to bring the stone to Quarton.

They arrive on Quarton happily showing off the Tenkai Stone to Beag but Vilius’ guardians show up. The knights fight them and then Dromus shows up too. The guardians attack Dromus and joke about him fighting alone but the Tenkai Knights back him up.

The guardians keep on making jokes but then Gen says he is a Tenkai Knight as well unless one of the current Tenkai Knights is against that. Nobody opposes so Gen tells the other Tenkai Knights for them to go destroy the other robots together.

They easily win against the guardians and by the end of the battle they comment on how much better the Tenkai Knights are now that they have five members and Guren welcomes Gen to the group.

They then go to the Tenkai Fortress to open the Fortress with the Tenkai Stone.
