Zak Adama is a fictional male Human Pilot in the Battlestar Galactica series. The character was portrayed on screen by Tobias Mehler. His allegiance / loyalty is to The Battlestar Galactica. Zak Adama in the re-imagined series is only seen through flash-backs such as in Act of Contrition. Zak was killed two years before the events of the Cylon invasion.
Zak was in a relationship with Lt. Kara Thrace ( Starbuck ) who was also his training instructor. Kara let her feelings for Zak get in the way and she passed him on a test when she shouldn't have done. We don't actually see the accident that resulted in Zak death. The death caused the relationship between Zak's brother Capt. Lee Adama ( Apollo ) and their father Commander William Adama. Kara reveals the truth to Lee as both pilots are leaving to go into battle. When asked why Kara was revealing it now, Kara replies that its the end of the world.
Kara would later confess to Commander Adama who rages but tells Kara that she needs to get back on the job and train new pilots. Over time, Kara heals the wounds by the revelation with both William and Lee.
In the first episodes, we get to see Zak Adama. Zak is a new Colonial Viper pilot who is eager to prove himself. When Capt. Apollo and Lt. Starbuck are about to go on a reconnaissance mission, Zak shows he's keen to go. Starbuck feigns an injury and therefore Zak takes Starbucks place on the mission.
The mission doesn't go to plan as the pilots come into contact with a group of Cylon Raiders. Zak's Viper is damaged and can't get back to the Galactica forcing Apollo to leave his brother behind. Apollo had to get back to the Battlestar Galactica to warn them of the incoming Cylons otherwise everything would have been lost.
