The Cybermen were a collective of cyborgs that had once existed as flesh and blood creatures. The race originally came into being when the planet Mondas, Earth's twin planet, drifted out of the Sol System. Cut off from the Sun, its inhabitants, the Mondans were stuck on a dying planet and had to adapt to survive without natural processes. As their bodies aged and grew sick, they began to replace the damaged pieces with mechanical components. However, the transformation continued until it resulted in total loss of individuality and emotion, and bore an artificial species who operated on cold logic, thinking all others should become like them. Cybermen were purely concerned with self-preservation, upgrading others into their ranks through any means necessary, and killing the incompatible or those who opposed Cyber-conversion. The Cybermen even existed in a parallel universe, brought about as the brainchild of the late John Lumic. These Cybermen crossed the barrier between universes and united forces with the Mondan Cybermen, upgrading each other to greater echelons. These advances reached their height when the Cybermen adapted for war, resulting in their most sophisticated and deadly evolution to date.

The top-level category for species is category:species. We know what you're thinking: "Why did we make it too difficult to figure out?" Well, the admin staff of this wiki delight in making things as hard to figure out as possible. .
If you like alien species that are based on Earth animals, you're in luck. All you have to do is go to the page of an Earth mammal and check out the "looks like" box. For instance, if you wanna know what aliens look like elephants, just go that pachyderm's page and find yourself a breadcrumb at the top of the page.
One of the cooler species categories is species by biology. Take a gander! That category will help you find species by the special biology they have. Aquatic species, energy beings, species with binary vascular systems — they're all here waiting for you.
Maybe no publication has been so active in the creation of off-the-wall species than Doctor Who Adventures. Some of the funkiest names in DWU history come from that mag. Both Homozillians and Hussuloofian come from DWA – and we've not even looked outside the hs.
