HILDEGARN

Hirudegarn or Hildegarn (ヒルデガーン, Hirudegān) is the enormous monster and main villain in the Dragon Ball Z movie, Wrath of the Dragon. He is a simple beast that wrecks and kills everything in his way.
The ancient monster Hirudegarn existed thousands of years prior to the events of the series, on an Earth-like planet in the southern galaxy named Planet Konats.
He was apparently turned to stone with the use of an enchanted sword and a pair of enchanted ocarinas, and sealed away in a temple by Tapion's and Minotia's ancestors, until a group of star traveling black magicians (known as the Kashvar) arrived on Konats, and used a dark spell to bring the monster back to life. The monster immediately went on a rampage, killing everyone who tried to get in his way, and devastating the planet. Tapion and his brother Minotia managed to freeze the monster in his tracks by each playing a pair of enchanted ocarinas found in th wraiths temple, giving a good wizard the opportunity to cut the monster in half with an enchanted sword. Since Hirudegarn couldn't be killed at the time, his upper-half was sealed in Tapion and the other half in Minotia and in this way the brothers became legends.
However, fearing that the Kashvar would try to revive the monster again someday, the brothers were separated, each sealed in a music box oracle by the wizard, and were shot into opposite ends of the galaxy far away from each other by the Konats war council, with the oracle holding Tapion landing on Earth.
A thousand years later, in the present, the last of the Kashvar, named Hoy, had vowed to resurrect the monster to rule the universe. He released Hirudegarn's lower half on a distant planet and easily disposed of Minotia, who got crushed under the feet of the monster. And then, he successed to release other half from Tapion's body. Finally, the full Hirudegarn can be defeated by Son Goku with his special technique, Dragon Fist.
