Years back in the Clone Wars, X5-91 was a Battle Droid that as plenty of personality to his "person" compared to most of his fellow droid brethren. His memory with the wars is somewhat "fuzzy" as he puts it. Near the end of the war he was buried in a old Separatist base and shut his programming down to preserve his life. Only to be reactivated by chance when a skirmish erupted above the buried base and managed to free his mildly damaged body. From the drop from his resting place jolted the reactivation protocol to which he woke with his left arm dysfunctional and he began dragging himself due to his legs also being out of order. After much time crawling through much of the remains of his base with random quakes breaking out from above. After making his way out a old ventilation shaft he made visual with the forces of the Rebel Alliance and Empire.

In the midst of the outbreak of fighting between the two factions a rebel trooper stumbles across the battered droid and oddly brought him back with him to the rebel front.

Justice: The character has a strong, unshakable sense of right and wrong, and he sees the injustices of Imperial rule throughout the galaxy. He is committed to seeing justice brought back to the galaxy, and he wishes those who have betrayed it to receive the punishment they deserve.

Personnel - After his pick up by the Alliance he is fixed up and is briefed about the past many years since the Clone Wars concluded. He processes the facts and sees he can help fight the now "newly" named Galactic Empire, decides to help fight and protect in the name of the Rebel Alliance as his saviors and new found friends.
