Mickey Mouse, a mouse, was born on the planet of Hyperion during the twilight years of the Galactic Republic. He was Force-sensitive, and ended up joining the Jedi Order. With the Order, he was taught to wield the Force, and to fight with a lightsaber. Mouse rose in the ranks until becoming a Jedi Master. During his career, he often joined forces with other Jedi Knights including Yoda, the Grand Master of the Jedi Order himself. Mouse greatly benefited from his superior's erudition and understanding nature. Together, the diminutive masters proved that no warrior should be judged by their size, and that defeatism could be conquered. In 22 BBY, an alliance of seceding star systems known as the Confederacy of Independent Systems declared war against the Republic. During the resulting conflict, known as the Clone Wars, the Jedi were called on to lead the Republic's newly formed Grand Army. Mouse was granted his own Eta-2 Actis-class interceptor, in which he flew with his astromech droid partner, R2-MK.
