Minnie Hooper, who referred to herself as Minnie the Menace, was an outgoing old woman and a friend of Wilfred Mott. She was a member of the Silver Cloak. She was locked inside an old 1960s police box for "misbehaving" on a bank holiday in August 1962, a story which she told to her fellow pensioners when searching for the Doctor's TARDIS.
After tracking down the Tenth Doctor, she wanted to be in a photo with a "handsome man", as she described the Doctor. She became the Master along with the rest of the human race. She later attended Donna Noble and Shaun Temple's wedding in the spring of 2010 where she teased Wilf by telling him she was going to catch him as her man. (TV: The End of Time)
