Walker (Tardisode 8)
From Tardis Wiki, the free Doctor Who reference
Walker was the captain of the Sanctuary Base 6 crew. He signed a deal with Macmillin to get back the energy-saving Krop Tor. He was killed by an Ood when he got The Beast's key. It can be presumed that he named the expedition after himself. (TS: Tardisode 8)
