The Daleks were a race of mutant life forms that originated from the Kaled race of the planet Skaro. Originally named the "Mark III Time Travel Machine", they were transformed into weapons of conquest by their creator, a maniacal Kaled scientist named Davros. His creations eventually turned against him, purporting they were superior lifeforms, and began to proliferate the universe as a deadly scourge that sought to wipe out any living thing that was not pure Dalek. The Daleks grew to such malignancy that they became the ultimate nemesis of the entire Time Lord race, and triggered the Last Great Time War. The Daleks are also the oldest and most despised enemy of renegade Time Lord using the alias The Doctor, a hatred that magnified with the Time War and culminated in his double genocide of both Time Lord and Dalek alike. However, the Daleks persisted in small numbers and gradually restored themselves to power once again.

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.
