4. Abzorboloff
No John Prescott didnt make a guest appearance in Doctor Who, this is the Abzorboloff from Planet Klom. The joke planet of the Doctor Who universe, and one of the worst monsters in the series for many a reason. This entry goes onto the list with mixed emotions. On one hand this monster is inseparable from the memory of one of the worst episodes since the shows revival, so its hard not to look back on its memory with distain. On the other hand the original design came from a kid who sent it into a Blue Peter competition, so it feels a little mean to say its a bad design. But it is. Its Peter Kay dressed as a giant ball of dried snot...with a Mohawk. The worst part of the design are several faces of his absorbed victims dotted around his body. This isnt a bad feature in itself, but the faces, which are still able to speak when shown in close up shots are clearly static moulds of the actors when in mid and long shots. To superimpose the actors faces into every shot would have required Star Wars and Avatar level use of green screen and CGI, so its understandable that the BBC wouldnt stretch that far and you can forgive the slight cheap result. What you cant forgive is that the BBC let a kid design something which caused them to produce a cheap design.
