Subtitle: Ice Super Beast (氷超獣 Hyō Chōjū?)

- Weight: 34,000 t
- Origin: Valley of Idatoge
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 timer blinked due to the severe cold. Ace fired his Metalium Beam 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 Legend The Movie.
Powers and AbilitiesEdit
- 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.
