The Daleks

"SURRENDER OR YOU WILL BE EXTERMINATED!!"

Of all the alien races The Doctor has encountered, the Daleks are by far the most dangerous and most evil of them all. Daleks are created for the sole purpose of exterminating all other life. Daleks are genetically engineered to be without mercy or remorse. They have no sense of compassion or mercy, and will kill without a second thought about it. In addition, they are not only capable of translating and speaking almost any known language, but are also highly intelligent and master tacticians. There is only one single entity in the universe that the Daleks fear: The Doctor. In the legends on the Daleks homeworld, Skaro, The Doctor is known as "The Oncoming Storm", and is commonly referred to by them as "The Predator".
