Planet of the Ood
They are all just called ood apart from one which is called Ood Sigma. Ood Sigma Is the ood which sees the doctor in most Doctor who episodes which have the ood in them.
Ood Sigma.
The Elder Ood was indeed Brian Cox in part one of the finale however, in the first part, you saw Ood Sigma, played by Paul Kasey, greet the Doctor and take him to the meeting of the Oodkind (where the elders sat and allowed the Doctor to link in the circle). In part 2 of the finale the Ood character that spoke the Doctor as he stumbled toward the Tardis was Ood Sigma, again played by Paul Kasey. The Character of the Elder Ood was seen only as a flashback to the first part of the Finale when the Doctor was taken to the Elder gathering.
It is unknown whether the Ood have genders, the Doctor refers one of the Ood as a 'he', so either they're all male, or some are female as well.
No. They are a separate species - from another planet, the "Ood Planet" - who have been enslaved by humans.
