Clyde (Revolution of the Daleks)

Clyde was the name given by the Thirteenth Doctor to a Sycorax, who shared a cell with an Ood, aptly named "Bonnie", in the prison together, adjacent to the Doctor's cell, during her sentence. They both roared and snarled at the Doctor, as she greeted them whilst walking past their cell. (TV: Revolution of the Daleks)
