Subtitle: Ice Terrible-Monster (氷超獣 Hyō Chōjū)
Yapool decided to freeze all of Japan so he unleashed his Terrible-Monster 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 Terrible-Monster. 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.
- Iceron is one of the monsters that makes up Belyudra'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 Terrible-Monster 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. On the other hand, since Iceron is part of Belyudra as mentioned above, it is likely he may have been finally killed off-screen at some point.
