Eve (The Last Dodo)
From Tardis Wiki, the free Doctor Who reference
Eve was the curator at the Museum of the Last Ones. She wanted to preserve the Tenth Doctor in the newly-opened Gallifrey section. She was eventually revealed to be an android.
Eve was obsessed with collecting the last of every species. After she found out that it would be impossible to finish her job, she self-destructed. (PROSE: The Last Dodo)
