Perfecting the duck face years in advance to the invention of cell phones, the first Silurians were pretty upset with humans for waking them up from underground hibernation. As revenge, they thought that taking over the world (again) might be a good idea.

 

Silurians were first seen in Doctor Who and the Silurians, Warriors of the Deep, and have made a reprise in the newer series with The Hungry Earth, Cold Blood, and many other episodes.
