Claudio
From Tardis Wiki, the free Doctor Who reference
Claudio was an Auton styled after a Roman soldier from a book of Amy Pond's. There were no real Romans in the episode, despite being the right time period. He was affected by River Song's Hallucinogenic lipstick and believed her to be Cleopatra, and the Doctor to be Caesar. He later helped place the Doctor in the Pandorica when the Nestene Consciousness took over him. When the Doctor negated the Cracks in time, the Alliance was never created and Claudio never existed.
