Yearning for adventure, Mickey joined the pirate ship Vagabond as the sole felinoid member of the crew and became its helmsmen. However she eventually became at odds with the methods used by Captain Arkady and his general lack of respect or compassion for the crew (particularly, that he considered their lives disposible). Eventually she turned on him and was instrumental in helping Lucy mutiny and take control of the ship. After this adventure, she defected and joined the CH-7 and was given a field commission. Mickey appears to be at least partially felinoid panthera pardus (most felinoids being felinoid sapien catus).
