Claudio was an Auton styled after a Roman soldier from a book of Amy Pond's. He was affected by River Song's hallucinogenic lipstick and so believed her to be Cleopatra, and the Eleventh Doctor to be Caesar. He later helped put the Doctor in the Pandorica when being controlled by the Nestene Consciousness. (TV: The Pandorica Opens) When the Doctor negated the cracks in time, the Alliance was never created and Claudio never existed. (TV: The Big Bang)
