Ultraman Zero The Movie: Super Deciding Fight! The Belial Galactic Empire

Iaron is one of Kaiser Belial's generals when raiding planets. Iaron was first seen leading a squadron of powerful ships to attack Mirror Knight's home planet, the Planet of Mirrors, in order to stop Run and the crew from reaching the Shield of Baraji. Iaron and the Ship Squadron were successful in destroying the Planet of Mirrors and thus were able to capture Run in the process. Later on once Ultraman Zero and Kaiser Belial battle. Iaron is left to deal with Mirror Knight on his own inside Kaiser Belial's ship. The battle between Iaron and Mirror Knight was at a perfect standstill, but once Mirror Knight found a crack in Iaron's powerful armor he trapped Iaron inside a dome of mirrors and fired a Mirror Cross attack at him. Iaron foolishly allowed the attack to ricochet him harmlessly, believing he was safe, but as he charged up his Iaron Sonic attack, the Mirror Cross impaled him through his crack and Iaron was destroyed.


  • Voice actor: Norio Wakamoto
  • Much like Shiyu, Iaron is heavily based on the Mirrorman kaiju, Iron, which is fitting, given that Mirror Knight is designed as a reference to Mirrorman.
  • In a premature script, it was originally planned that Darkgone and Iaron were once agents of Yapool, but then defected from him and joined Kaiser Belial. This fact was still kept for road shows during the film's promotions.
