Doc Cottle is the Battlestar Galactica's irrascible Chief Medical Officer (CMO). In keeping with Sci-FI medical officers, he is somewhat eccentric - a heavy smoker, despite knowing the risks, and one not overly impressed by positions of power.

He is the third person in the fleet to learn about President [[Laura Roslin]'s cancer condition (Act of Contrition), after Lee Adama (Bastille Day) and Billy Keikeya (Mini-Series). He has agreed to treat her condition, without revealing it to anyone else - and has further agreed to help her with more unorthodox treatments such as Kamala Extract.

He took a personal interest in Starbuck's recovery after she broker her leg (You Can't Go Home Again), and worked with Lee Adama to get her out of sickbay (Six Degress of Separation) - without success.

Grumpy of attitude, yet always professional, Cottle instantly inspires trust, despite his attitude.
