Jack Dark is Joanna's father.Ex-marine, former cop, now single parent of a young woman. Jack Dark has seen it all and lived to tell about it. Now a bounty hunter for hire, Jack runs his own outfit, Dark Bail Bonds, while passing on everything he's learned over the years to Joanna. Morally driven, Jack's major business challenge is avoiding the giant hypercorps as his ethical viewpoints don't often see eye-to-eye with the executives. In times of financial stress, Jack has no idea how his own life and the lives of those he cares for will be affected after accepting an anonymous rescue operation.
On the mission 1, he, Chandra, and his daughter Joanna Dark, go to a club whose Boss was Killian (a criminal who helps dataDyne to trash their radioactive substances at the sea). He has Zeigler's data and is very valuable for dataDyne and for the Carrington Institute, so, they have to recover it without fails.
On the mission 2, Joanna is sent to recover the data, while her father takes care of Zeigler because of his injuries.
On the mission 3, Zeigler dies, fortunately, Joanna and Jack escape, but with a new problem: dataDyne's troops on the roofs. They escape, but Jack is captured by dataDyne's agents.
On the mission 4, Joanna is sent by Chandra to rescue her father on the Huan-Shang mountains. She just find information, and faces Mai-Hem on a Deathmatch duel. Joanna wins.
On the mission 5, Joanna infiltrates into a hidden dataDyne's lab. There, she rescues Jack, pissing off Mai-Hem.
On the mission 6, Jack and Joanna try to escape with a vehicle, but they have to disrupt the signal of an antenna, so Mai-Hem wouldn't be able to search their run. When they reached a place where was a ship, they find Mai-Hem with some of her troops, and they started shooting. Mai-Hem told them that she just wanted the information Zeigler put on Jack's head, but then, Jack apologizes Joanna, grabed her gun, and started shooting to all troops, including Mai-Hem. She avoids the bullet, and quickly shoots Jack and he just fall. While this, Joanna ran to the ship and with no doubt, she just pilots it. Jack surrenders in front of Mai-Hem, and she just shot him on his head, killing Jack. Joanna gets pissed, and burns Mai-Hem with the ship. There, Jack's life ends.
