Yapool decided to freeze all of Japan so he unleashed his choju Iceron to do it. A boy called to his dead father who became the monster Woo. The two monsters fought until Iceron pushed Woo off a cliff. Hokuto became Ultraman Ace and fought the freezing choju. Iceron was a formidable opponent and Ace's Color Timer blinked due to the severe cold. Ace fired his Metalium Ray and caused an avalanche, burying Iceron alive.
- Iceron has a modified Hedorah roar with a little buzz at the end that sounds similar to Black Satan's roar.
- Although not physically seen, Iceron is one of the monsters that makes up Beryudora's left arm in Mega Monster Battle: Ultra Galaxy Legends The Movie.
- Iceron is the first instance of a kaiju's defeat being put off until later, Ace burying the choju in ice since his energy was nearly depleted making it so he had to deal with its threat sooner. Despite this, he is never seen destroying Iceron, leaving its fate somewhat ambiguous and giving it the possibility of returning.
Powers and Weapons
- Icy Breath: Iceron's breath is an extremely cold mist he uses against stronger enemies.
- Icy Wind: Iceron can surround himself in an icy wind to confuse humans, but it is useless against enemies that are kaiju size.
