Trivia

 * When this mode is unlocked by the Tenkai Knights, each knight is surrounded by an aura.
 * After each knight unlocks this mode, they can use it any time they like.
 * In the english dub, the knights always say a phase after the transformation, like: Yeah, I'm on FIRE! (Bravenwolf). Alright! Time to plug'n play! (Valorn). Yeeaah, Game on! (Lydendor). Oh yeah, so cool! (Tributon). Watch out! There's a storm coming! (Dromus). All being a reference to their element or their favourite hobbies.
 * Tributon was the only knight who didn't unlock Elemental Titan mode by fighting a Guardian. Instead, he unlocked Elemental Titan Mode by fighting Venetta.
 * Dromus was the only knight to unlock Elemental Titan Mode by trying to fight two Guardians.
