K9 (2009)

One of the more tenuously connected spinoffs of the 2005 Doctor Who reboot; whilst Torchwood, Sarah Jane Adventures and Class were official spinoffs, K9 was only made because creator Bob Baker owned the rights to the character of K9 and nothing else. As such, there's no real connections to the actual series, and was filmed in Australia. The makeup and special effects credits are paltry; a Sharon Robbins is just credited for 'makeup' and David Pawsey and David Napier are credited as 'puppeteers', but nothing else.

The series had a very low budget which meant most of the aliens were just realized as guys in static masks, such as the Anubians, but some prosthetic makeups and practical suit creatures were still made; one recurring evil alien was the Korven, primate-like aliens with wing-like crests on their head.

Another alien that was all too briefly seen was the Meron, a catfish-like alien with fins on the head; a prosthetic latex mask and hands were made, but this guy only appears for a couple of seconds tops.

One other prosthetic makeup alien was this 'Custodian', realized as an ogre-like creature with horns and lumpy green skin, as well as mantis arms.

The most impressive alien effects in this series were the Jixen, turtle-like creatures that come across as a bit inspired by the Skeksis from The Dark Crystal. The Jixen seem to be full body suits, which makes me wonder who realized them; did they have some veterans of Farscape working on this show or something? I'd love to know the behind the scenes info if anyone there has it!
