Waterman (Dr. Who Meets the Watermen)

The Watermen were reptilian-looking humanoids.

A group of Watermen from Q20 landed their ship after experiencing troubles with it. They came across the First Doctor, Ian Chesterton and Barbara Wright and introduced themselves to the group. The Doctor investigated their ship and determined that the fault of their ship was due to faulty wiring. After the Doctor repairs the issue, they embark on a 5 million light-year journey back to Q20.
