He-Man and the Masters of the Universe

Disappearing Dragons (2x16)

:

He-Man is summoned to Darksmoke by Granamyr, who tells him that dragons have been mysteriously disappearing from Dragon Mountain, and he wants He-Man to investigate. He-Man calls upon his most trusted spies, Mekaneck and Buzz-Off, to investigate the mystery, and they spot Kobra Khan and Webstor using a strange machine to transport the dragons to another dimension. A spell by Orko accidentally transports all of them- both heroes and villains- to the alien world, and the heroes discover that the dragons are being used to fight for amusement by three gamers on this world. It is up to the heroes to put a stop to the games and free the dragons from cruelty.
