Demon Magician
From Tardis Wiki, the free Doctor Who reference
The Demon Magician, or Magician of the Forest, was a malevolent entity who used his magic to interfere with Santa Claus's toy making. He tried to stop the First Doctor, John and Gillian from helping Santa, first by making a huge wall to block their way, then by animating a snowman to attack them. After escaping from both traps, they defeated the Demon Magician by shrinking him with the Doctor's magic box, then trapping him in a toy rocket which they launched. (COMIC: A Christmas Story)
