Elemental Mode

Elemental Mode is a powered-up version of a regular Quartonian and can only be activated by the Tenkai Knights and Vilius.

It was unlocked in "Vilius Returns", when Vilius sealed the Knights' ability to turn into Titan Mode. He then took the five Dragon Cubes out of the Tenkai Knights and Dromus, deactivating Phoenix Mode then combined the cubes and revived the dragon, but because he used his powers to create the dragon without a Dragon Key, the Tenkai Dragon was rendered unstable. The dragon would change from its light and dark forms. The dragon was so unstable that a single strike from Dromus was enough to split the dragon up into ten black and white dragon cubes, representing its good and evil forms.

The five white Dragon Cubes went into the four Knights and Dromus, while the five black cubes went into Vilius. Since the Knights had no Titan Mode, they were forced to retreat, which made them angry and left a big gap in their power. They now had to figure out how to defeat the Corrupted without Titan Mode in their arsenal. After a quick talk with his dad, Guren realizes that they need to change along with their powers if they want to stand a fighting chance. After attempting to beat Titan Granox and failing, the Knights work together to immobilize him. Their changing of strategy combined with the power of the Tenkai Dragon Cubes allowed them to access a new mode, Elemental Mode.

This change appears to be permanent, as now when the Knights travel to Quarton, they automatically appear in Elemental Mode. Their names have also slightly changed, to whatever their elemental attack is. It is deactivated by expelling the dragon cubes from their bodies.

Appearance
Elemental Mode gives the Knights new colors, each of their respective element. Their helmets expand as well, and their wings get added onto, each slightly differently. Their legs, arms, and chest plate appear a different color than the rest of their body, and their weapons appear a slightly different color as well. Guren's Core Brick also changed color to red.

Abilities
Elemental Mode grants the user powers which cause more damage then when in regular form. Their Tenkai Energy also increases, as well as their attack and defense. They are granted immense power that they did not have in their regular form. It is hinted that they also get new minor attacks, such as new ice arrows or flaming swords. It also grants each Knight a new power, their own elemental powers, as determined by their name. Each of their attacks are slightly different. The new elemental powers have proven to be powerful enough to turn enemies from Titan Mode back to regular mode in a single blow. They are also able to transform the Blastank and Volt Jet into the Ice Walker and Flame Phoenix.

Bravenwolf Firestorm
Bravenwolf's Elemental Mode is called Bravenwolf Firestorm (Japanese:  バーニング・ブレイヴン , Bāningu Bureivun, Eng. Translated: Burning Braven ). His elemental attack allows him to summon a giant ball of fire on the tip of his sword and throw it at the target.

His color also change from yellow to yellow and light orange, his arms, legs, inner chest plate, and back of his helmet changing to light orange.
