"Saber of Red" and Servant in the Holy Grail War, Mordred is prideful and haughty.  She does not even think of failure, boasting overpowering words from a clear and unclouded voice that shows dignity befitting of a king.  Due to a wish from the Holy Grail, her Master has transformed her into a living pool toy, able to be inflated whether using an air tank, a pump, or simply via the Command Seal of his Master.  While she outwardly denies it, Mordred secretly enjoys being inflated.
