ZEXAL (power)

ZEXAL is a miraculous power that, according to The Door, is the one that can turn darkness into light. Astral claimed it is a legendary power which once saved the Astral World.

It was first mentioned when The Emperor's Key turned off, and the voice of The Door told Astral that the promised time has come to obtain ZEXAL, a power which can turn all the darkness into light. Later, the Door reappeared to Yuma and gave him the power. When Yuma obtained it, he and Astral were combined. Interestingly, they were combined the same way as monsters are overlaid during an Xyz Summon, which they call it "Xyz Change ZEXAL".

When the combination was completed, Yuma realized that his appearance had completely changed, as he was wearing an armor that gave him a golden aura, and had given him golden hair and one golden and one red eye. In this form, Astral was sharing his body. Using its power to perform a "Shining Draw", Yuma obtained a new monster to help "Utopia Ray" defeat Kaito's "Galaxy-Eyes Photon Dragon".

Trivia

 * This is the second game mechanic used to fuse two characters into one; the first one would be Jaden Yuki using "Super Polymerization" to fuse with Yubel, though the second instance is not as permanent.


 * Yuma while in this form looks very similar in appearence to that of a Super Saiyan from the Dragon Ball franchise.
