The Friends of the Ood are an organisation that are determined to liberate the Ood from slavery. (DW: The Impossible Planet)
Dr. Ryder was fighting for Friends of the Ood and it took him ten years, but he managed to free the Ood Brain for long enough for it to communicate with the Ood on the Ood-Sphere. (DW: Planet of the Ood)
Other pro-Ood supporters include the Tenth Doctor and Donna Noble who had saved the Ood from corporate slavery and were to be remembered by them in song. (DW: Planet of the Ood). Also Rose Tyler had shown sympathy and even questioned the Ood about their treatment, however she and the Doctor couldn't investigate this further as the Ood became possessed by the Beast. (DW: The Impossible Planet, The Satan Pit) The Doctor later regrets not doing something sooner, in conversation to Donna. (DW: Planet of the Ood)
