Marissa Flores was a young female Human in the 24th century. In 2368, she was one of three children given a tour of the USS Enterprise-D by Captain Jean-Luc Picard as a reward for the best science projects at that year's science fair. She was the oldest of the children, but was incredibly shy. As a further reward for the bravery the children showed Picard promised to resume their tour later, this time including the battle bridge.
