Bio: In Marvel comic continuity, Jackie was the daughter of Dr. Katherine Pulaski. She was a member of the Maquis, and created a biological weapon which backfired upon the peoples living in and around the Badlands. Her mother risked her career to find her and to create an antidote to the virus. When the threat of the plague passed, Jackie distanced herself from the Maquis, but had to stand trial in Federation court for her actions. The result of that trial remains a mystery, but Sisko indicated that he thought leniency would probably be granted, given Jackie's change of heart away from the Maquis.
Notes: Jackie's full name is never specified in dialogue but a computer display screen confirms that her last name is indeed 'Pulaski'.At right is a scene depicting the emotional crux of the Jackie/Katherine story line: Katherine cradles Jackie on her lap as the younger Pulaski falls victim to the very plague she helped create.
