This is a list of characters from the TV series Martha Speaks.
The BookBots are robot superhero versions of Martha, Helen, T.D., Alice, and Truman, who were invented by the gang in The Martha Show, Part 2. They have wacky inventions and when given the choice of going on missions in disguise, they usually choose to be pirates. Most of the gang play themselves. They also have an oath that they live by: "I pledge allegiance to books and words because books and words express ideas, and without ideas, our brains wouldn't do anything (except keep the wind from whistling through our empty robot heads) with liberty and justice for all (rights reserved)."
