20 Doctor Who Characters Who MUST Return

20. Canton Everett Delaware III

When Canton Everett Delaware III was introduced in 2011, Doctor Who was breaking the American market, and Nicholas Courtney had sadly left us. Against that backdrop, it felt like Steven Moffat was introducing a Brigadier surrogate to honour Courtney's legacy, and appeal to American audiences.

Mark Sheppard was a well-known face to fans of American TV due to his roles in Battlestar Galactica and Supernatural, but alas, Canton never returned. Over a decade later, and with Doctor Who striving to be a global brand, perhaps the time is right for another America-based adventure with the former FBI agent.

How brilliant would it be to see Canton in charge of an American branch of UNIT in the 1970s or the 1980s, leading the organisation like a cross between Fox Mulder and the Brigadier? Yes please.
