He-Man and the Masters of the Universe

Daimar the Demon (1x17)

Air date: Sep 27, 1983

While bored, Orko casts a spell to bring a small, cute creature called Daimar, from a book about the dimension of darkness, to Eternia. But Daimar doesn't stay cute for long- he soon turns into a giant demon and is threatening to overcome Grayskull with his power, which Skeletor is also determined to acquire for himself!
