Bakugan: Rise of the ResistanceEdit
Dr. Xeron first appeared when the Brawlers were following Asteria to the Hurranian hidden base in the Lake. Eva revealed that Xeron is the Hurranian top scientist and Eva's ex-boss, and also the creator of the Bakugan Replicator. He wanted to punish Eva for her betrayal towards the Hurranian Empire, challenging them to a battle. He ordered Ceros and Asteria to leave him, saying that it was his battle, but when he lost, he said that his forces were at a more important battlefield. He then received a call from General Phobos, who told him that the Emperor Hurranos demanded the latest Replicator to him, and he immediately followed that order.
Later, inside the hidden Hurranian base, Dr. Xeron sent a message to the Hurranos, telling him that his six invasive armies were almost generated, and that they will be soon transported to Vestal. When he received the order, he left the base alongside Asteria and Typhoon.
He was later spotted in the Forest, with the Hurranian army behind him. He battled against Eva using the power of his mightiest Bakugan, Bolcanon, but was still defeated by his former assistant, shocked by the fact that his little weak ex-assistant defeated him. Xeron then received a transmission call from Phobos, who told him that the Emperor demanded his presence immediately, so he left with his army.
He and Phobos returned when the Brawlers infiltrated the Hurranian Mothership. He was willing to defend Hurranos at any cost, and unleashed a final battle against the Brawlers. After he was defeated, he apologized to Hurranos and escaped.
Dr. Xeron appeared once again in the throne room of Emperor Hurranos. He was ordered by Hurranos to take control of Eva, which he successfully did. Xeron then ordered her to attack the humans, but Eva's soul was stronger than her programing, and she returned to her old self. Dr. Xeron was shocked to see this, and escaped afterwards.
