Ultraman Tiga
During the events of "Ultraman X The Movie", X was defeated by Zaigorg and the X Devizer took a huge damage, rendering him untransformed for a moment until the appearance of Ultraman Tiga, which was transformed by Yuto healed the device and finally being able to join the battle once more. Joining with the original Ultraman and Ultraman Tiga, X fought against Zaigorg but once the monster captured the former two's energies, X gained Beta Spark Armor which he used to free them and empower the Ultra Warriors from the worldwide to destroy Tsurugi Demaaga before finishing Zaigorg. X separated from Daichi, revealing that throughout the battle he was able to regain his physical body and set his sight to depart from Earth. Before departing, he thanked Xio for their cooperation since the first time they met and reassured to Daichi that they will always stay united. Sometime later, he returned to Daichi after Desastro made its way to the planet.
