Ivy (Evacuation Earth)

Ivy was a the board computer of the SS Lady Gray.

Ivy could talk. She was a high security computer and noone ever managed to hack into her system until some worker did so to find a lost relative.

When Ivy lost the connection to the cooling mechanisms of the SS Lady Gray and the engines were overheated, the Eleventh Doctor and Amy Pond helped her to restore the connection.

Ivy then helped the Doctor and Amy to find the TARDIS which was put onto the SS Lady Gray. (GAME: Evacuation Earth)
