Daughter of Sir Hugh and Amelia Creighton-Ward, Lady Penelope is a member of the British aristocracy.

In the eyes of the public, she is a beautiful socialite. Stylish, elegant and poised, Penelope is a true English Lady. Combined with her love of danger, action and intrigue, she is a cool-headed top secret agent. Lady Penelope operates the UK division of International Rescue.

Lady Penelope is portrayed by Sophia Myles in the live-action Thunderbirds movie. In the classic TV series, the character was voiced by Sylvia Anderson.

"The thing about Lady Penelope is she's such a fantastic role model for young children - bright, funny, strong and sexy without being provocative. It's nice to have a role model who isn't dancing around with her midriff showing." -- Sophia Myles
