Donna Noble /ˈdɑːnəˈnəʊbəl/: The most important woman in all of creation. Travelled with The Doctor helping several civilisations. She gained Time Lord abilities and knowledge, which transformed her into The DoctorDonna. However, in order to keep her from dying, The Doctor had to erase all memories of her travells through time and space from her mind. It is unclear if she ever regained those memories. She later married Shaun Temple.
