The Killing Jar
The Quintessons are ever expanding their research on living beings, and decide to conduct a study on a new group of subjects. Marissa, Cyclonus, Magnus, and Wreck-Gar are captured and put into cages for study. The Quints toy with them, gaging their interactions, and don't notice the ship is dangerously near a black hole; they are sucked into a negative world. The Quints end up studying how everyone works together as they all cooperate to find a way of pulling the ship out.
