Bonnie (Revolution of the Daleks)

Bonnie was the name given by the Thirteenth Doctor to an Ood, who shared a cell with a Sycorax, aptly named "Clyde", 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)
