Well I can't really compete with the fact that Bryan Talbot has been awarded an Honorary Doctorate of Arts from Sunderland University, but I'm not sure even he can claim to be a character in Doctor Who.
Or two, even. A brand new Doctor Who story appearing on the BBC website commemorating the moon landings features a pair of evil CIA agents called Spencer and Milledge (sic).
'We are Agents Spencer and Milledge, Secret Service. Under Code Seven of Revised Project Blue Book, we invoke the rights approved by the late President John F. Kennedy regarding first contact.'
The three part story Blue Moon by Oli Smith starts with a prologue and the agents make their appearance towards the end of episode one. The third and final chapter is published on Monday.
Top that, Doctor Talbot!
