Yes it's about time to look back at the latest series of Doctor Who and the new aliens that appear in the series - to be fair there are a lot of 'sort-of' species in this post, creatures that technically aren't really new aliens at all but are worth mentioning nonetheless
I didn't know quite what to make of these creatures, they added a good deal of menace to what weoul otherwise have been a load of random exploring...but then again I'd have been happy with just random exploring!!
These creatures, roaming the core of the TARDIS, a result of the Doctor and his companions being exposed directly to the eye of Harmony. Thankfully the Doctor was able to change the course of events so that these creatures ceased to exist.
A quirky little alien in a nice episode starting with the Companions helping Clara and the Doctor and then taking the fight back to the enemy. I have to say the little leech was a nice mix of cute and evil and a nice take on a species type - don't think we've had a small wormy thing for a while on Who!
An ancient race, known as a menace to the Silurtians when they populated the Earth. They produced a venom which could cause horrific changes and death in conact with most humans but could also have a symbiotic and beneficial relationship with a chosen host body. One surviving member of the race, conspired with a corrupt human, Mrs. Gillyflower to take over the human race.
Another new Cyber-thingy, but I thought these little creatures were effective and better than last series' rebooted Cybermat with it's snappy teeth, these creatures were actually a threat. It was nice to see the actual Cybermen being more powerful and threatening than they have been in the past.
A weapon of the Cybermen, Cybermites were part of their arsenal in their longstanding war agains humanity. Cybermites could latch onto an organic host and begin the process of converting them into a Cyberman. They weren't able to convert a host by themselves but could turn a being into an agent for them and certainly incapacitate foes if they got close enough. They were also able to turn the Doctor into 'Mr Clever' and alter ego with some of the Doctor's personality and knowledge and yet fully serving the Cybermen.
Another vague non-race designed to add some threat, these 'whisper men' were actually manifestations of the Great Intelligence and did not corporeally exist at all, though they could interact with the world, they were used by the Intelligence to threaten the Doctor's friends to make him open up his tomb on Trenzalore.
That's your lot - more after the Anniversary Special!!
