|“||Aeon the Terrible! He was determined that Rudolph would not find Happy and he intended to do everything in his power to stop the little red-nosed reindeer.||„|
|~ Father Time narrating about Aeon|
Aeon the Terrible is a giant talking buzzard and was the main antagonist in the 1978 Christmas special Rudolph's Shiny New Year. He could live for one eon and when it was up, he would turn into ice and snow. He lives on the Island of No-Name: a giant iceberg near the north pole, where the sun never shines. He spent ages terrorizing those who lived in the Sands of Time: a desert near Father Time's castle.
In the film, Happy, the baby new year ran away after being laughed at for his big ears. When Aeon learned of this, he knew that if the baby is not brought back to Father Time before midnight of the new year, then time would stop and Aeon would not die. He searched drastically for the baby. Father Time asked Rudolph, the Red-Nosed Reindeer, to search for Happy and Rudolph proudly accepted. Father Time told Rudolph that Happy would be hiding on a series of islands called the Archipalego of Last Years. Aeon found Rudolph sailing towards the islands and tried to stop him but was stopped by Big Ben, the clockwork whale. Both Aeon and Rudolph had no luck finding Happy for two days until they found him on the medieval, fairy-tale island. Aeon found him first and flew off. Rudolph and Big Ben chased Aeon and squirted water at him and the water made him drop Happy. Happy landed on the 1776 island and Aeon found him and captured him. He promised Happy that he would take care of him. Aeon brought him back to his island home to live with him on New Year's eve.
Rudolph and his friends found the island and attempted to rescue Happy but they had only 30 mins to do so. They tried to climb up the iceberg but with no avail. Aeon spotted them and let out a horrible shriek which caused an avalanche and encased the rescue team in snowballs. Rudolph managed to melt the snow with his nose and found Happy in Aeon's nest while the buzzard was sleeping. Rudolph convinced Happy that having big ears was a good thing and Happy's reaction woke Aeon up. Happy then showed his ears and Aeon began to laugh. He laughed so hard that he fell out of his nest and freed the rest of the rescue team from their snowballs. Aeon realized that by laughing uncontrollably, he could not turn into ice and snow. When Santa arrived to bring everyone back to Father Time, Aeon waved goodbye and continued laughing. What happened to him afterwards is unknown.
