Garris Cain
From Battlestar Wiki, the free, open content Battlestar Galactica encyclopedia and episode guide
Lt. Garris Cain was a Viper pilot stationed on the battlestar Galactica during the opening of the Cylon War, where he was a wingman of Adama. He was impulsive, impatient, hotheaded, and a risk-taker, irritating (and being irritated by) his felow wingmen, Paulus and Iphigenia. However, he was nonetheless an excellent pilot who completed his missions succesfully.
He is the Video Game's version of the show's Commander Cain.
