Elemental Titan Mode

Elemental Titan Mode is a a combination of the Tenkai Knights's Titan Mode and Elemental Mode which 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. This mode can be activated by Bravenwolf Tenkai Firestorm, Tributon Tenkai Iceblast, Valorn Tenkai Terrablast, and Lydendor Tenkai Lightningstrike.

It appears that the Knights cannot use Elemental Titan Mode unless they go through the steps to unlock it again.
