was Mirror Knight, who emerges and frees Run so that he may transform into Ultraman Zero. The final battle between Ultraman Zero and Kaiser Belial then proceeds and the two battle to a standstill. However, Kaiser Belial unleashes a Deathcium Ray and incapacitates Ultraman Zero before fleeing. Meanwhile, Iaron and Mirror Knight face off in Kaiser Belial's headquarters and Darkgone faces off against Jean-bird, who is running out of power. With no other option, Emerana sacrifices herself to fuel Jean-bird with her own Emerald energy by locking herself into his main engine, allowing Jean-bird to transform into his more humanoid robot form known as Jean-bot. With Nao's help, Jean-bot destroys Darkgone and Mirror Knight is victorious in killing Iaron as well. Suddenly, Ultraman Zero finds Kaiser Belial standing atop a mountain of Emeralds he had harvested from planets and Kaiser Belial proceeds to absorb its massive energy qualities, transforming Belial into a towering monster known as Arch Belial. Now physically towering and unstoppable, Arch Belial overpowered and tortures Zero as Mirror Knight and Jean-Bot are unable to stop him. Miraculously, Glenfire returns and rescues Ultraman Zero, as well as reveals that he and the Pirate of Flames also brought along help in the form of the Planet of Mirrors army and the Esmeraldan royal guard who survived the invasion of the planet (starting scene), whom altogether hold off Belial's Legionoid and ship fortresses. Arch Belial however intends on destroying Zero and Esmeralda with his Arch Deathcium Ray. Ultimately during the battle with Belial and having all energies in his bracelet used up, Zero's strength is spent and finally dies from exhaustion. Now understanding the purpose of the Shield of Baradhi, Nao informs everyone not to lose hope and eventually, Zero is revived and brought forth by Ultraman Noa, who bestows the Shield of Baradhi onto Zero, transforming the Ultra into Ultimate Zero. With his enhanced powers, Ultimate Zero destroys Arch Belial with the Final Ultimate Zero, saving the universe from his tyranny. With Belial gone for good, tranquility returns to the universe. Princess Emerana reveals to have survived using her energy to power Jean-bot, the Ultras back in M78 are revealed to have not only survived but has also stopped Belial's forces as well, and Ultraman Zero separates from Run's body, allowing him to live a normal life with Nao again. Ultraman Zero proceeds to head back to his home
