39. The Ice Warriors

Introducing the Ice Warriors! Big giant lizard warriors from Mars! Sssssssss!!! This is the first of four appearances throughout the 2nd and 3rd Doctor's tenure. This story will be released on DVD in a few months with its two missing episodes animated, so for the first time we will be able to see the story in its most complete version since its original broadcast. I'll provide a more proper review when the DVD comes out.

In the meanwhile, the Ice Warriors will be turning to television in an upcoming new episode of Doctor Who! Yeah!! Ssssssssss!
