After Seaman took the flute, he produced the noisy demon to produce insurrection, which was responded by the Giant Saver. After the battle, the guards returned back to the supernatural research institute. Don, Corina and Uncle Frank came to know about the situation. During the talk, Uncle Frank put forward the new discovery of Giant Saver. He believed that the combination of the Giant Braver and Assault Saver could make a more powerful robot. This theory surprised them. Quinn and Zoe expressed their objection. They held that the respective battle king could fight respectively and either one should take the order of the other. However, Kearney supported Uncle Frank¡¯s view. Nevertheless, when Don asked how to combine the two Savers, Kearney couldn¡¯t answer it. Soon Seaman and the demon caused troubles again. All the guards were ready to fight against the demon with the sound-proof earplugs invented by Uncle Frank. However, during the fierce battle, the earplugs lost the functions. Under the guidance of Kearney, the two robots combined together, and the combined robots defeated the demon and controlled the super elf.
