Urbankans
Biology
The Urbankans were green-skinned humanoids with lumpy features and clawed hands. They were bald and had two bumps over their eyes. They could excrete a deadly poison out of glands on their necks. One trillionth of a gramme of this poison could reduce a humanoid to the size of a grain of salt.
Technology
The Urbankans were very advance and their technology even rivalled that of the Time Lords. One of their most important developments was their androids which could be made in a variety of appearances. The androids were much tougher and stronger than organic light although they were light and could be stopped when their computer chips were removed.
