Purple was the second-in-command before the crash. Now with the lack of a Captain, the crew finds themselves unfortunately under the command of this smug, egotistical, and lazy excuse for a leader.
Before the crash, Red spent her time on the ship being the best she could be. She consistently proved her skill and competence above the rest of the crew. Red’s promotion to Captain seemed guaranteed, and then Purple happened.
After being declared, “unfit for action” Green worked on board before the crash as the crew’s Cook. Green lived a sheltered life before the crash, mostly confined to the kitchen on the ship. Cook duties on the ship mostly meant pressing a single button or two in order to start all the machinery and robots that prepared the crew’s space-food.
Prior to the crash-landing Blue worked on the ship as its weapons expert and senior engineer. This gave Blue opportunities to meet Green when the kitchen machinery would occasionally break down. Blue has a lot of energy to go around, especially now that all his favorite things are broken.
