Elemental Titan Mode

Elemental Titan Mode (a combination of the Titan Mode and Elemental Mode) was unlocked by Bravenwolf in "Dojo Mojo". He used it to defeat Guardian Boreas's Mega Fusion. It was then unlocked by Valorn in "Toxic Toxsa" to defeat Guardian Zephyrus's Mega Fusion. Then it was unlocked by Lydendor in "Fight Knight" to defeat Guardian Notus's Mega Fusion. Finally, it was unlocked by Tributon in "Beware Betrayal" to save Bravenwolf from being defeated by Venetta. This mode can be activated by Bravenwolf Tenkai Firestorm, Tributon Tenkai Iceblast, Valorn Tenkai Terrablast, and Lydendor Tenkai Lightningstrike.

Abilities
This mode gives them a combination of their Titan Mode powers, including enhanced abilities, and Elemental Mode powers, including Elemental Attacks. It is currently unknown if there are any other added powers.

Appearance
This mode is activated by the Knight changing into his bigger core brick, surrounded by his respective element. He then receives the normal attachments of Titan Mode, except in the respective new colors. They also get bigger wings and helmets. Their weapon grows bigger and can sometimes be shown surrounded by their element.

Trivia

 * When this mode is unlocked by the Tenkai Knights, each Knight is surrounded by an aura.
 * After each knight except Bravenwolf Tenkai Firestorm unlocks this mode, they can use it any time they like, Bravenwolf can't do this for an unknown reason.
