Cobb (The Doctor's Daughter)
Cobb was a general encountered by the Doctor, Donna on the planet Messaline. He commanded Cline and the Doctor's daughter, Jenny.
Cobb asked the Doctor to join them in the war against the alien Hath. He sought "the Source" and it was his mission to get it. He had the Doctor and Donna arrested along with Jenny for not supporting him in the war. As he found out that the three of them had broke out he chased them down into secret passageways.
When Jenny hesitated before shooting him she instead his a gas pipe to hold them up on the advice of her father not to kill him. When the Doctor restores peace to Messaline upon finding the Source, Cobb blamed the Doctor for taking away his chance of victory, and tried to shoot him. Jenny stands between them but Cobb shoots her through one of her hearts and (temporarily) killed her. Devastated and desiring revenge for Jenny's death, the Doctor held a gun to Cobb's head, contemplating shooting him. The Doctor manages to stop himself, telling Cobb that "[He] never would" and that it is on that basis that the new society should he founded. Cobb was demoted, arrested and locked away.(DW: The Doctor's Daughter)
